Transmission and Gearing
The RX 100 featured a 4-speed constant mesh gearbox. The gear ratios were carefully selected to provide:
- Quick acceleration from a standstill
- Adequate pulling power for Indian road conditions
- A top speed of around 100 km/h (hence the “100” in its name)
The gearshift pattern was the universal 1-down, 3-up configuration, making it easy for riders to adapt to.
Chassis and Suspension
The frame of the RX 100 was a single downtube, dual-cradle design that provided a good balance of rigidity and flexibility. This was paired with:
