Isle of Man TT

The Isle of Man TT or Tourist Trophy races are an annual motorcycle racing event run on the Isle of Man in May and June of most years since its inaugural race in 1907. The event begins on the UK Spring Bank Holiday at the end of May and runs for thirteen days. It is often called one of the most dangerous racing events in the world as many competitors have died.[1]

Overview

The Isle of Man TT is run in a time-trial format on public roads closed to the public by an Act of Tynwald. The event consists of one week of practice and qualifying sessions followed by one week of racing. It has been a tradition, perhaps started by racing competitors in the early 1920s, for spectators to tour the Snaefell Mountain Course on motorcycles during the Isle of Man TT on Mad Sunday,[2] an informal and unofficial sanctioned event held on the Sunday between Practice Week and Race Week.[3]

Mad Sunday has now been abolished: Race Week starts on the Saturday and continues for each of the next few days.

The first Isle of Man TT race was held on Tuesday 28 May 1907 and was named the International Auto-Cycle Tourist Trophy.[4] The event was organised by the Auto-Cycle Club over 10 laps of the Isle of Man St John's Short Course of 15 miles 1,470 yards for road-legal 'touring' motorcycles with exhaust silencers, saddles, pedals and mudguards.

From 1911, the Isle of Man TT transferred to the much longer Snaefell Mountain Course of 37.40 miles (60.19 km) (current length 37.73 miles (60.72 km)). Its elevation goes from near sea-level to 1,300 feet (400 m).[5] The race programme developed from a single race with two classes for the 1907 Isle of Man TT, expanding in 1911 to two individual races for the 350cc Junior TT motor-cycles and the Blue Riband event the 500cc Senior TT race. The race did not take place from 1915 to 1919 due to the First World War. It resumed in 1920. A 250cc Lightweight TT race was added to the Isle of Man TT programme in 1922, followed by a Sidecar TT race in 1923.

There was no racing on the Isle of Man between 1940 and 1945 due to the Second World War. It recommenced with the Manx Grand Prix in 1946 and the Isle of Man TT in 1947, with a greatly expanded format that included the new Clubman's TT races. The Isle of Man TT became part of the FIM Motor-cycle Grand Prix World Championship (now MotoGP) as the British round of the World Motor-Cycling Championship during the period 1949–1976. Following safety concerns with the Snaefell Mountain Course and problems over inadequate "start-money" for competitors, there was a boycott of the Isle of Man TT races from the early 1970s by many of the leading competitors, motorcycle manufacturers and national motorcycle sporting federations.[6]

It is regarded as the most dangerous motorsport event in the world; The New York Times said in 2017 that the number of deaths had risen "to 146 since it was first run in 1907; if one includes fatal accidents occurring during the Manx Grand Prix ... the figure rises above 250".[7][8] An account of the 2003 race by Sports Illustrated writer Franz Lidz called the TT "a test of nerves and speed that may be sports' most dangerous event."[9]

In 1976, the Isle of Man TT lost its world championship status; this was transferred to the United Kingdom by the FIM and run as the British Grand Prix for the 1977 season. The Isle of Man TT Races then became an integral part of the new style TT Formula 1, Formula 2 and Formula 3 World Championships between 1977 and 1990 to develop and maintain the international racing status of the Isle of Man TT races.[10]

The event was redeveloped by the Isle of Man Department of Tourism as the Isle of Man TT Festival from 1989 onwards. This included new racing events for the new Isle of Man TT Festival programme, including the Pre-TT Classic Races in 1989 followed by the Post-TT Races from 1991, both held on the Billown Circuit. In 2013, the Isle of Man Classic TT was developed by the Isle of Man Department of Economic Development and the Auto-Cycle Union for historic racing motorcycles, and along with the Manx Grand Prix, it formed part of the 'Isle of Man Festival of Motorcycling' held in late August of each year. The Classic TT brand ceased operation prior to the 2022 event, with classes for historic racing motorcycles integrated into the Manx Grand Prix. The TT is now promoted by the Isle of Man Government Department for Enterprise.

There has been criticism of the event. In 2007, an incident during the Senior Race resulted in the deaths of a rider and two spectators.[11] The resultant inquest made several recommendations and included several comments, such as: 'Senior Marshals may well have been elevated beyond the sphere of their competence'.[12] The coroner also noted that "I am more than aware of the fact that the witnesses from the Manx Motor Cycle Club and the marshals are all volunteers. They give their time freely and without paid reward. Having said that however, if it were suggested because they were volunteers there should be some allowance in the standards expected of them, then I regret I cannot agree."[13]

In 2018, a solo competitor was seriously injured during a head-on collision with an official Course Car being driven at high speed when conveying police officers to officiate at the scene of a fatality further along the course. He was one of seven riders who had been halted on the course and turned back by marshals, being instructed to proceed back to the paddock area in the reverse-direction after the red flag stoppage.

The 2020 and 2021 TT races were cancelled because of the COVID-19 pandemic.[14][15]

Early Isle of Man TT race history (1904–1910)

Gordon Bennett and Tourist Trophy car races

Motor racing began on the Isle of Man in 1904 with the Gordon Bennett Eliminating Trial, restricted to touring automobiles. As the Motor Car Act 1903 placed a speed restriction of 20 mph (32 km/h) on automobiles in the UK, Julian Orde, Secretary of the Automobile Car Club of Britain and Ireland approached the authorities in the Isle of Man for the permission to race automobiles on the island's public roads.[16] The Highways (Light Locomotive) Act 1904 gave permission in the Isle of Man for the 52.15-mile (83.93 km) Highroads Course for the 1904 Gordon Bennett Eliminating Trial which was won by Clifford Earl (Napier) in 7 hours 26.5 minutes for five laps (255.5 mi or 411.2 km) of the Highroads Course. The 1905 Gordon Bennett Trial was held on 30 May 1905 and was again won by Clifford Earl driving a Napier automobile in 6 hours and 6 minutes for six laps of the Highroads Course. This was followed in September 1905 with the first Isle of Man Tourist Trophy Race for racing automobiles, now known as the RAC Tourist Trophy and was won by John Napier (Arrol-Johnston) in 6 hours and 9 minutes at an average speed of 33.90 mph (54.56 km/h).[17]

International Motor-Cycle Cup Race (1905)

For the 1905 Gordon Bennett Eliminating Trial it was decided to run an eliminating trial for motorcycles the day afterwards for a team to represent Great Britain in the International Motor-Cycle Cup Races. An accident at Ramsey Hairpin forced out one of the pre-race favourites, and the inability of the competitors to climb the steep Mountain Section of the course forced the organisers to use a 25-mile (40 km) section of the Gordon Bennett Trial course. This ran from Douglas south to Castletown and then north to Ballacraine along the primary A3 road and returning to the start at the Quarterbridge in Douglas via Crosby and Glen Vine along the current Snaefell Mountain Course in the reverse direction. The 1905 International Motor-Cycle Cup Race for five laps (125 mi or 201 km) was won by J.S. Campbell (Ariel) despite a fire during a pit stop[18] in 4 hours, 9 minutes and 36 seconds at an average race speed of 30.04 mph (48.34 km/h).[19]

Format of the races
Competitors line up at the start of the 2010 Senior TT race

The TT Races since the first race in 1907 have been in the format of time-trial. The races held on the Clypse Course during the period 1954–1959 were the more traditional full grid starts along with the 1924 Lightweight TT Race and Clubmen TT Races from 1948, which were also "mass-start" races. The current format is a "clutch start" and race competitors will be "started singly at 10-second intervals".[20]

The first event on the new course was the Junior TT Race contested by 35 entrants, won by Percy J. Evans riding a Humber motor-cycle at an average race speed of 41.45 mph (66.71 km/h). The 1912 event was the first to limit the Junior TT to only 350 cc machines and this engine capacity prevailed until 1976, after which the category was dropped. The event was instead run for 250 cc machines until 1994 when replaced by the 600 cc Supersport class.

2022 saw the introduction of the supertwin race ran over 3 laps on Wednesday the 8th of June, increased to 4 laps the following year. The class is very similar to the lightweight class which last ran in 2019, although with some differences. The maximum capacity has been increased to 700cc allowing the Yamaha YZF-R7 and Aprilia RS660 to compete. In 2022 bikes with capacities of 651cc+ were required to run 10kg heavier than the 150kg limit for the 650cc machines, but 2023 saw this changed and all bikes in the class now have a minimum weight of 150kgs. [24]

Sidecar TT

The 1923 TT was the first time the Sidecar TT race was run, over three laps (113 mi or 182 km) of the Mountain Course and was won by Freddie Dixon and passenger Walter Denny with a Douglas and special banking-sidecar at an average race speed of 53.15 mph (85.54 km/h). For the 1926 event the Sidecar and Ultra-Lightweight TT classes were dropped due to lack of entries.

The Sidecar race was re-introduced from the 1954 event for Sidecars not exceeding 500 cc engine capacity, run on the Clypse Course. A non-championship 750 cc class for sidecars was introduced at the 1968 event. For the 1976 event the race was held over two-legs. From 1975, the previous 500 cc and 750 cc classes for Sidecars were replaced by a 1000 cc engine capacity class.

For the 1911 Isle of Man TT, the first TT event using the Snaefell Mountain Course or Mountain Course, two separate races were introduced. The first event was a four lap Junior TT race and a separate Senior TT race for 500 cc single-cylinder and 585 cc twin-cylinder motorcycles, over five laps of the new 37.5-mile (60.4 km) Snaefell Mountain Course. The new technical challenges of the Mountain Course forced changes on entrants and motorcycle manufacturers alike. The American Indian motorcycle factory fitted a two-speed gearbox and chain-drive. This proved to be the winning combination when Oliver Godfrey won the 1911 Senior TT race riding an Indian at an average speed of 47.63 mph (76.65 km/h). Fitted with a six-speed belt drive[25] Charlie Collier riding a Matchless motorcycle finished second in the 1911 Senior TT race and was later disqualified for illegal refuelling. During an early morning practice session for the 1911 Isle of Man TT races, Victor Surridge died after crashing his Rudge motorcycle at Glen Helen, the first death of a competitor on the Snaefell Mountain Course and the first death in the Isle of Man of a person in an automotive accident.[26]

  • 1911 For single cylinder motorcycles not exceeding 500 cc engine capacity and 585 cc twin cylinder motorcycles.
  • 1912–1939 For motorcycles not exceeding 500 cc engine capacity.
  • 1947–1948 For motorcycles not exceeding 500 cc engine capacity and a ban on engine supercharging.
  • 1949–1976 FIM World Championship event for motorcycles not exceeding 500 cc engine capacity.
  • 1977–1984 for motorcycles not exceeding 500 cc engine capacity.

The 2015 specifications for entries into the Senior TT race are:

  • TT Superbike: (Machines complying with the 2015 FIM Superbike Championship specifications)[27]
    • Over 750 cc up to 1000 cc 4 cylinders 4-stroke
    • Over 750 cc up to 1000 cc 3 cylinders 4-stroke
    • Over 850 cc up to 1200 cc 2 cylinders 4-stroke
  • Supersport Junior TT (without limitation of tyre choice)
    • TT Superstock (without limitation of tyre choice)
    • Other machines admitted at the discretion of the Organisers.

TT Zero
Main article: TT Zero

Starting from the 2010 races, the TT Zero event over one lap (37.73 mi or 60.72 km) of the Snaefell Mountain Course replaced the TTXGP. The TT Zero event as an officially sanctioned TT race is for racing motorcycles where "The technical concept is for motorcycles (two wheeled) to be powered without the use of carbon based fuels and have zero toxic/noxious emissions".[28] The Isle of Man Government offered a prize of £10,000 for the first entrant to exceed the prestigious 100 mph (160 km/h) (22 minutes and 38.388 seconds) average speed around the Mountain Course. This was achieved by Michael Rutter of team MotoCzysz in the 2012 race,[29] and has been exceeded every year since.

In 2019, a moratorium on further events in this class was announced, due to the slow take-up in electric motorcycles. Speaking about the future of the event, Enterprise Minister Alex Allinson has ruled out further competition in this class until at least 2024.[30]

Ultra-Lightweight TT
Main article: Ultra-Lightweight TT

1924 was the first time the Ultra-Lightweight TT race took place for motorcycles not exceeding 175 cc engine capacity. It was won by Jock Porter, riding a New Gerrard motorcycle at an average speed of 51.21 mph (82.41 km/h) over three laps of the Snaefell mountain course. The Ultra-Lightweight class was re-introduced in 1951 for motorcycles not exceeding 125 cc until discontinued in 1974, and then re-introduced for 1989, again for two-stroke 125 cc motorcycles, until dropped again due to lack of entries after 2004. The event was reintroduced 2008–2009 held on the four-mile Billown Circuit and then dropped from the race schedule on cost grounds for the 2010 races.

  • 1924–1925 For motorcycles not exceeding 175 cc engine capacity.
  • 1951–1953 FIM World Championship event for motorcycles not exceeding 125 cc engine capacity, held on the Snaefell mountain course.
  • 1954–1959 FIM World Championship event for motorcycles not exceeding 125 cc engine capacity, held on the Clypse Course.
  • 1960–1974 FIM World Championship event for motorcycles not exceeding 125 cc engine capacity, held on the Mountain Course.
  • 1989–2004 for motorcycles not exceeding 125 cc engine capacity, held on the Mountain Course.
  • 2008–2009 for motorcycles not exceeding 125 cc engine capacity, held on the Billown Circuit.
  • 50 cc race 1962–1968, an additional World Championship event for Ultra-Lightweight motorcycles not exceeding 50 cc engine capacity, held on the Mountain Course.

Clubman TT and Production TT

The Clubman races with Lightweight, Junior and Senior classes were held for production motorcycles from 1947 until 1956.[31] A Senior 1000 cc class provided an opportunity for Vincent motorcycles.[32] The riders were little-known, but as the stars were barred from entering the class, it provided a stepping-stone for future-stars but resulted in less spectator-interest. The series became dominated by one model – the BSA Gold Star,[33][34][35] and with little competition from other manufacturers, was discontinued. When previewing the impending re-introduction of a specification-controlled, roadster-based class in March 1967, David Dixon wrote: "lack of inter-make rivalry probably put the final nail in the coffin".[33]

Writing in UK monthly magazine Motor Cyclist Illustrated, racing journalist Ray Knight, who had achieved a lap speed of nearly 88 mph on a Triumph Tiger 100 roadster-based racing motorcycle in the Manx Grand Prix,[36][37][38] commented in early 1965 that the ACU had refused a request from manufacturers to run a production TT race, which he thought was a missed opportunity, particularly considering the dwindling support for the 500 cc race.[39]

A Production TT for roadster-based motorcycles having classes for maximum engine capacities of 250 cc, 500 cc and 750 cc was introduced from 1967 until 1976 when the class was discontinued.

The Production TT was reintroduced for the 1984 races in three classes, reduced to two classes on safety grounds for the 1990 races. For the 2005 races the Superstock class replaced the previous 1000 cc and 600 cc Production TT classes that had been part of the race schedule since 1989.

Lightweight TT

The 1922 event was the first time the Lightweight TT race took place, won by a motorcycle-journalist Geoff S. Davison, riding a Levis at an average speed of 49.89 mph (80.29 km/h) for seven laps of the Snaefell Mountain Course. In the changes following the loss of FIM World Championship status after the 1976 event, the Lightweight TT event was dropped with the 250 cc machines running for the Junior TT in place of the now defunct 350 cc formula. The Lightweight TT returned in 1995 before being split into two distinct events from 1999, dropping from the schedule again after 2003. As with the Ultra-Lightweight TT Race, it was reintroduced 2008–2009 when held on the Billown short road circuit and then dropped again from the race schedule on cost grounds.

  • 1924–1948 For motorcycles not exceeding 250 cc engine capacity.
  • 1949–1953 FIM World Championship event for motorcycles not exceeding 250 cc engine capacity, held on the Snaefell mountain course.
  • 1954–1959 FIM World Championship event for motorcycles not exceeding 250 cc engine capacity, held on the Clypse Course.
  • 1960–1976 FIM World Championship event for motorcycles not exceeding 250 cc engine capacity, held on the Mountain Course.

  • Machines must comply with general technical rules as per ACU Standing Regulations and 2019 Isle of Man TT race regulations.
    • Any four-stroke twin cylinder motorcycle originally sold for road use with a water-cooled engine of up to 650 cc engine capacity.
    • Eligible machines must be from models homologated for UK road use 2009 or later.

Minimum weight for the Lightweight TT class is 161 kilograms (355 lb).[41]

TT course official vehicles

After the completion of a practice or race period, an official course vehicle displaying the notice Roads Open proceeds around the Mountain Course, passing each point opening the roads including side-access junctions to public use. On the Snaefell mountain road section from Ramsey to Douglas, the official vehicle displays the notice Roads Open One Way.

Travelling marshals

Originally introduced in 1935, there are eight machines positioned around the course to provide a rapid response to any incidents. Selected riders have previous race experience and are first-aid trained, with machines carrying medical equipment that can assist in managing a casualty. They also have other duties such as course inspection, observation of machines on the course for visible faults, and review and report any course incidents.[42] As of 2023, all travelling marshals ride Honda CBR1000RR Fireblades.[43]

Crossing places during practice and races

The 1982 Road Racing Act (Isle of Man) and the supplementary TT Road Races Orders allow vehicles and pedestrians to cross the Snaefell Mountain Course at certain points between scheduled race periods under the supervision of a police officer. Several permanent pedestrian overbridges have been erected. These points include:

In Douglas

TT Course access road
Part of the access road passing under the A1 Peel Road

The TT Access Road runs parallel to a section of the A1 Peel Road, which is part of the Snaefell Mountain Course, and operates during practice and race periods to enable vehicles to pass from inside of the race course to the outside. It runs along a section of former railway line on the historic Douglas to Peel route, from the junction of the A5 New Castletown Road at the Quarter Bridge, passing under the course at Braddan Bridge, to an exit at Braddan School Road in Douglas outskirts, near the former Braddan Railway Halt and the A23/Ballafletcher Road junction. The access road is a narrow, single-track width with passing places and is restricted to cars and light vans below a weight limit of 3,500 kilograms (3.4 long tons; 3.9 short tons). When used for vehicular traffic, pedestrian access is prohibited, but at other times it is part of a system of nature trails.[44][45]

Incidents
Main article: Isle of Man TT Mountain Course § Safety
See also: List of Isle of Man TT Mountain Course fatalities

Between 1907 and 2023, there have been 155 fatalities during official practices or races on the Snaefell Mountain Course, and 266 total fatalities (this number includes the riders killed during the Manx Grand Prix, and Clubman TT race series of the late 1940s/1950s).[7][46][47] In 2016, 5 riders died on the course during official practices or races.[48][49][8][50] There were six fatalities among competitors in the 1970 Isle of Man TT, making it the deadliest year in the history of the event.[51][52]

2018 Course Car incident
Sidecars returning to Paddock past Sarah's Cottage in reverse direction to a normal race after a red flag caused by a competitor's crash in 2009

On 30 May 2018, an experienced TT rider, Steve Mercer,[53][54] was seriously injured during a head-on collision with an official Course Car at Ballacrye. The car, being driven at high speed,[55][56] was conveying police officers to officiate at the scene of a fatality involving Dan Kneen. Mercer was unconscious for five days and hospitalised for five months due to multiple injuries. He was one of seven riders who had been halted on the course and turned back by marshals, being instructed to proceed back to the TT Grandstand area in the reverse direction after the red flag stoppage.[57][58] Immediately after the accident the organisers changed their protocols, requiring that returning riders must be controlled by motorcycle-mounted travelling marshals to the front and rear.[59][60] An independent inquiry into the circumstances was arranged by ACU Events, the event organisers.[61]

The Auto-Cycle Union, the Isle of Man Department for Enterprise, and the inquiry report author, lawyer Rob Jones, a former chief executive of the Motor Sports Association, all refused to release the report as it was confidential and privately owned by the ACU.[56][58][62][63]

The ACU admitted liability for the accident, but instructed that any legal claim for compensation by Mercer must be filed in the Isle of Man. The ACU stated that Mercer was receiving financial assistance through its "extensive insurance arrangements".[54][64][65]

In 2019, it was reported that the driver of the car in the collision had quit after criticism that he exceeded a newly introduced speed limit recorded by a GPS tracking device when he drove to attend a fatality involving Chris Swallow at Ballaugh in August's Senior Classic TT. Gary Thompson, Clerk of the Course and an ACU employee, had been criticised in 2018 for also fulfilling the role of Safety Officer; consequently a new incumbent was in place for 2019.[56][66][67]

Cancellations

World Wars I and II

From 1915 to 1919, and 1940 to 1946, no TT events took place, due to the outbreak of World Wars I and II.[68] Events continued from 1920 to 1939 and 1947 to 2000.

Since TT 1947, the Isle of Man TT has only been cancelled three times: 2001, 2020 and 2021, all of which were due to viral outbreaks.

2001 cancellation

The 2001 Isle of Man TT races were cancelled because of the outbreak of foot-and-mouth disease in the UK in the spring and summer of 2001. Disinfecting 40,000 spectators and competitors (and their motorcycles) to ensure the disease was kept off the island proved difficult.

2020 and 2021 cancellations

In March 2020, the Isle of Man Government announced the cancellation of the 2020 TT due to the ongoing COVID-19 pandemic.[69] The Classic TT was subsequently cancelled in May,[70] and in December 2020, it was announced that 2021's TT races would also not go ahead, due to the continued worldwide spread of the virus.[71] In 2020, the Isle of Man Government lost an estimated £4.8 million of its annual projected revenue due to the cancellation of the TT races.[72]

The event returned in 2022 after a two-year absence.[73]

The Isle of Man TT was part of the FIM Motorcycle Grand Prix World Championship (now MotoGP) between 1949 and 1976. During this period the Isle of Man TT Races counted as the United Kingdom round including the Sidecar TT, 50 cc Ultra-Lightweight TT, 125 cc Lightweight TT, 250 cc Lightweight TT, 350 cc Junior TT and 500 cc Senior TT races counted towards the FIM Motor-Cycle Grand Prix World Championship.

After the 1972 races, multiple world champion, 10-time TT race winner and dominant motorcycle racer of his time Giacomo Agostini announced he would never race again at the Isle of Man, declaring it too dangerous for international competition and that it was outrageous that such a race should ever be part of a scenario professional riders were forced into; at this point the Isle of Man TT was not suited to the growing professionalism and business aspects of Grand Prix motorcycle racing. More and more riders joined his boycott, and after 1976 the race was struck from the championship and replaced by the British Grand Prix.

Video games

There have been numerous video games based on the Isle of Man TT; the first was the 1995 Sega arcade game Manx TT Super Bike, which was later ported to the Sega Saturn in 1997.[97] Several other games have followed since, including Suzuki TT Superbikes (2005), TT Superbikes: Real Road Racing Championship and TT Superbikes Legends (both 2008), all of which were released exclusively for the PlayStation 2, and developed by Jester Interactive.

Bigben Interactive has since revived the TT game license, releasing TT Isle Of Man: Ride on the Edge in 2018 and two sequels in 2020 and 2023.[98][99][100]

Connected events

The Ramsey Sprint has been run since 1978 and is one of the biggest events during the TT race festival. The Sprint is run along the 1 km long Mooragh Promenade. The music festival Sprintfest is also held in the same town, Ramsey, on the weekend between practice week and race week.
