Ride Engineering YZ-BAB09-MB Axle Block, Blue for Yamaha YZ250F (2009-2011) and YZ450F 2009

Ride Engineering's YZ-BAB09-MB Billet Axle Block is made specifically for Yamaha YZ250F (2009-11) and YZ450F 2009.

Ride Eng. highly recommends using our new axle blocks on this bike. Not only are they precision machined for a better swingarm fit, but we placed the adjustment marks (15 per side) on the top surface for much more accurate chain alignment. Furthemore, our blocks are 6mm longer than stock, reducing "rocking" while keeping the chain adjustment bolts less extended. We also provide two M8 hex nuts to "double lock" the adjustment bolts and keep them from loosening.
