Assist & Slipper Clutch

An A&S (assist and slipper) clutch is adopted to reduce the weight of the clutch pull and provide low-stress shifting during deceleration. The A&S helps to reduce fatigue for the rider. This also prevents excessive engine braking, thus reducing its effects on chassis behavior. The A&S clutch makes for smooth, enjoyable downshifts.

Variable Valves Actuation (VVA)

This is a one-of-a-kind high-performance VVA system that provides torque for ease of use even at low RPM. There are two intake valve cams: one for low- to mid-range rpm and another for high rpm. They switch between each other at the 7,400 rpm mark to ensure good power and torque is present throughout the entire rev range.

Traction Control System

The R15 V4 comes with Traction Control System. This is a dedicated electronic system that has the remarkable ability of reducing the chances of a wheelspin (slippage due to loss of traction)

Quick Shifter

The Quick Shifter* (up-shift) allows for clutch-less shifting of gears. It increases the comfort of riding the vehicle since it eliminates the need to use the clutch or throttle before and after a gearshift.
