New R1-Derived KYB® Fork To ensure class-leading front-end feel and confidence, the 2017 YZF-R6 features the advanced KYB® 43mm fork found on the R1, tuned specifically for the R6. With excellent damping and awesome feedback from the front tire, the fork offers exceptional adjustability, with all adjustments at the top of the fork. The new fork also uses the R1’s large 25mm axle shaft, further boosting rigidity and wheel control. New KYB® Shock The lightweight swingarm pivots high in the frame, for increased anti-squat effect and mid-corner stability. A new piggyback shock design features four-way preload and damping adjustability for effective wheel control across a wide variety of conditions.
