With feedback and testing results derived from Star Racing Factory Yamaha, Ride Eng. came up with this link spec for 2009 and up YZFs. Our link improves handling mid-corner and balances out the bike.
Less effort is required to initiate turn-in and it keeps the bike tracking straight in whoops allowing the rider to be more aggressive. It also keeps the back end planted in breaking bumps.
This link lowers the back of the motorcycle 8-10mm. It comes complete with bearings, seals and the steel roller bushing.
Recommended sag with the Rideng Link is 102-106mm.
