Highlights include:
--New Piston
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.
--New Crank
Optimized crankshaft and counterbalancer designs feature a revised
balance ratio, predictive power delivery and reduced vibration.
--New ECU
New ECU settings provide smoother transition as the rider reaches
the rev limiter.
--New Brakes
New 270mm front disc brake, up from 250mm, uses new brake pad
material for exceptional stopping power and control for aggressive
corner entries.
--Updated Suspension
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.
