The only major change that the bike underwent was that it was upgraded from a 6-volt electrical system to a 12-volt system. The bike's production run lasted from Nov 1985 - Mar 1996. Various mods like expansion chambers, Disc brakes and 5th gear. 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. The newest RX100s available in the market today are 12 years old. Yet, there are people who are still looking out for one. The old advertising campaign slogans "Born to Lead" and "Ahead of the 100s" are aptly justified by this mean machine.
