Features
• Updated and lighter frame with streamlined rear shock mount, new engine mounts, revised wall thicknesses, and cutouts for improved chassis flex
• Upgraded tank shrouds using bi-compound plastics channel air towards the radiators more efficiently and have a new fuel tank roll for a tighter, more secure fitment
• Revised fork and shock settings
• Improved frame/shock geometry provides more ground clearance at the linkage
• New linkage seals refine rear shock response and advanced damping characteristics
• Smaller diameter linkage bolts save weight
• Upgraded rear brake pedal adds additional stiffness and braking feel
• New chain guide and chain guard
• Quickshifter function allows clutchless upshifts from 2nd to 5th gear
• Launch Control is easily engaged by pressing the traction control and Quickshifter buttons simultaneously and works by limiting the amount of power to the rear wheel, improving traction, and preventing loss of control under hard acceleration
• Map select switch changes engine character depending on track conditions and rider preference:
— Map 1 - linear, predictable power delivery
— Map 2 - crisp, explosive power output
— Traction Control is easily toggled to an on or off position from the same switch, ensuring maximum traction and a distinct advantage in wet or muddy conditions
