The Yamaha RX-135 (also popularly known under the name RX-King, RX-K, RXT, or simply RX in Southeast Asia, especially India, Indonesia, & the Philippines) is a two-stroke engine motorcycle produced by Yamaha since the 1990s.
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 Euro 3 regulations halted production. The late model RX-135 in Indonesia used a catalytic converter as part of the exhaust, which allowed it to pass Euro 2 regulations.
In Indonesia Yamaha RX King produced between 1983 and January 2009, so it's become legendary bike, especially in 2 stroke categories. Indonesian standard version of RX King can make 18,5 PS/9500rpm stock, with fuel efficiency around 35-40 km/liter of 88-octan premium. Because good availability of spare parts, and easy to maintain, until now RX King is one of the most wanted bike for two stroke speed lover, beside Kawasaki Ninja 150R/RR. Suzuki RGR 150, Satria 120 R or F-150, Shogun, Smash, Honda Supra X, Yamaha F1ZR Vega R, Jupiter Z, and Jupiter MX.
Standard modification to increase horse power include subtitution by racing parts can be done by small garage, such as exhaust and intake modification, CDI resetting, subtitution of carburettor or rejetting, subtitution of exhaust tube, reed valve, etc. By this perfect work, 135cc two stroke engine has capabilities to pass bigger bike on road, for example Honda Tiger 200 or Yamaha Scorpio 225, even Kawasaki Ninja 250R
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 Philippines the RX-135 is called RXT; it started production in 1992. It has notable differences from its Indian counterpart, such as a rectangular-shaped headlight instead of circular, a differently placed taillight bracket, and fuel tank cap. The RX-135 ended production in 2007 with the introduction of Euro 2 emission standards.
