Anyone know the OEM axle diameters for the F/R on a Ninja 300 ? (inch or mm). Mines a 2013 but I expect all 300's are the same. Dave
Sorry, front is 15 rear is 17. Look on ronayers.com, they have a parts blow up. Look under wheel(s) and the bearings. I just did a quick search so dont take it as gospel. Bearing ID is typically the first number.
