More torque at low revs means better drive out of corners, so our engineers changed the shape of the piston and connecting rod and optimized valve timing to help improve combustion consistency and thereby exhaust efficiency at lower revs. The bridged-box design of the piston uses a reinforcing structure between the skirt and the wrist-pin bosses that helps enable a high redline. Big torque down low, huge power up top. A winning formula.

The combination of 79 mm bore and short 50.9 mm stroke produces a high-revving engine with plenty of room for large titanium valves. The engine breathes and revs — the keys to making power. As well, the DOHC cylinder-head design let our engineers straighten out the intake and exhaust tracts to improve power and response. The intake is shorter and just about arrow straight, and the exhaust flows more efficiently too. You’ll experience more power and better throttle response.

HRC Launch Control: push the button to select the mode, hold the throttle open, release the clutch, and the bike will do the rest, launching you into the first turn with a big advantage.

This simple handlebar-mounted button lets you dial in engine power delivery character with a push of your thumb. Choose between Standard, Smooth, and Aggressive, depending on track conditions.
