Lambky Liner

The Lambky Liner is a motorcycle land-speed record streamliner designed by Navy veteran and Vincent motorcycle restorer Max Lambky from Kansas, United States.[3] It reached a top recorded speed of 250 mph (400 km/h) at the 2007 International Motorcycle Speed Trials,[1] and an estimated 275 mph (443 km/h) in second gear before a supercharger spindle broke and spoiled a run in 2008.[2]

Design and construction

World record holder Don Vesco consulted with Lambky on several features of streamliner design that Lambky utilized, including hub-center steering.[4]

The streamliner is powered by dual alcohol-burning supercharged Vincent Motorcycles pushrod V-twin engines, built in 1949 and 1952.[5][6][7] The total displacement is almost 2,000 cc running on alcohol, developing c. 400 horsepower (300 kW).[5][6]

Total weight with rider and fuel is 1,600 pounds (730 kg).[6] Frontal area is 4 square feet (0.37 m2).[8]

As of 2012, nine iterations of the streamliner had been built by Lambky, including a sidecar configuration.[3] Development costs were reported as $100,000 in 1997,[5] and over $150,000 by 2008.[6]

Riders

Riders included Don Angel, the first, who was recorded going 150 mph (240 km/h) through the timing lights backwards in 2006,[2] and Hartmut Weidelich, a German who also rebuilt the engines.[2][9][10]

Records

The streamliner won an award at the 2005 Speed Trials by BUB at Bonneville Speedway in the antique division at 212.86 miles per hour (342.56 km/h).[9][11]

In September, 2010, it set a new Southern California Timing Association (SCTA) record of 191.303 miles per hour (307.872 km/h) in the SCS-PBF class; SCS stands for special construction (hub steering, two engine) streamliner; PBF stands for piston, blown, (alcohol/nitro) fuel.[12]
