The engine produces around 50 horsepower, enabling rapid acceleration and a thrilling top speed.
Liquid cooling ensures consistent engine temperatures during hard riding sessions, enhancing reliability and performance. The dual Mikuni carburetors provide precise fuel delivery for optimal throttle response and power output. The kick-start system, although manual, is lightweight and reliable, keeping the overall weight down.
▌Transmission and Drivetrain
– Transmission: 6-speed manual gearbox with wet multi-plate clutch
– Drive Type: Chain drive to the rear wheels
– Gear Shifting: Foot-operated sequential shifting
The 6-speed manual transmission allows riders to fully harness the engine’s power by selecting the ideal gear for various terrains and riding conditions. The closely spaced gear ratios make it easier to keep the engine in its power band, whether climbing steep hills or sprinting on flat trails. The chain drive is durable and straightforward, offering efficient power transfer and easy maintenance.
