​This is the first ever 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.

Now shift gears without worrying about economy. The new R15S with 6-speed transmission allows to cruise at low RPM even in higher gears, thus saving fuel without missing on the thrill.

This liquid cooled single overhead camshaft fuel injection engine churns out 18.6PS@10000rpm and 14.1Nm@8500rpm. Features an advanced die cast aluminum (DiASil) cylinder with outstanding cooling performance.

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.
