The Yamaha RX100 is a 98 cc two-stroke single-cylinder air-cooled motorcycle that was manufactured between 1985 and 1996 in Japan and India. The model was followed by the 11.8 bhp 132cc RXG, which had a faulty ignition system, which was replaced by the company at no cost. Next came the RX135, which was essentially a rebadged RXG. The RXZ was launched with a sportier headlamp fairing. Finally, in the year 2000-2001 were launched the 14 bhp RX135 and the RXZ ( Both 5-speed with a catalytic converter silencer) . These met with luke warm response. The final variant was a 4-speed RX135 with a catalytic converter silencer, sporting a fuel gauge and speedometer with white dials which was sold very briefly in 2003.
