The RX-135 was released around the end of the 1990s. In selected Indian cities, a factory-shipped RX-135 could be bought until August 2009. There were two versions of the bike sold in India a 4-speed version and a 5-speed version. The 4-speed produced a power of 12 horsepower and the 5-speed version produced 14 horsepower.
In Indonesia the RX-135, initially named the RX-K, was produced from 1981 to 1982. The new 1983 model, which added a cubical tank design and a new more modern seat model, was released as the RX-King with a claimed power of 18.5 horsepower. It was produced until late 2009, when the requirements of the EURO3 regulation halted production. The late model RX-135 in Indonesia used a catalytic converter as part of the exhaust, which made it pass EURO2 regulations.
The RX-135 had also been initially introduced as RXG with similar engine capacity but with numerous changes in bottom-end gearing (primary ratio), sprockets and cylinder design, sticker design, ignition system and general looks.
In the Philippines the RX-135 is called RXT; it started production in 1992. It has notable differences from its Indian counterpart, such as rectangular shaped headlight instead of circle, taillight bracket placed differently, & fuel tank cap. The RX-135 ended production in 2007 with the introduction of EURO2 emission standards.
