I have a complete rear Warp 9 rear wheel for a 2009 YZ450 and want to use it on my 2006 WR450. The bearings I.D. on the hub are too large for my WR axle so I am hoping that I can just swap out the bearings to a different size. The Warp 9 hub is supposed to accept OEM bearings. Does anyone know what side bearings I would need or know the O.D. and width of OEM 2009 YZ450 bearings and the I.D. of OEM 2006 WR450 bearings?
