A new lightweight forged two-ring piston uses a flat piston crown surface with additional strengthening ribs and a shorter, more durable piston pin with diamond like carbon (DLC) coating. The new piston is lighter, significantly stronger and together with revised EFI mapping, improves combustion performance for a faster, more thorough burn, resulting in excellent pulling power.
--New Oil Jets
Revised piston oil jets direct oil underneath the new piston, to help promote cooling and contribute to more stable engine performance. --Updated Shifter
Revisions to the clutch boss and shift stopper arm provide smooth clutch engagement feel and more precise shifting action when the gate drops.
Optimized crankshaft and counterbalancer designs feature a revised balance ratio, predictive power delivery and reduced vibration.
New ECU settings provide smoother transition as the rider reaches the rev limiter.
New 270mm front disc brake, up from 250mm, uses new brake pad material for exceptional stopping power and control for aggressive corner entries.
New suspension settings front and rear are designed to eliminate sudden jolts and better control front-end dive, for a smoother, more balanced damping feel through the corner.
