20MM Offset Ride Engineering Triple Clamps 2008-2022 YZ450F & YZ250F. Used in good working order. Makes this Yamaha corner like a dream without noticeable loss in strait kine stability. Had these in my 2013 yz450. Come with Rubber mounted bar mount settup with poly cone spaces, 10mm offset Forward or rear bases, 10mm risers, and all hardware to put it together. Great overall system. Complete setup costs around 0 new.
