John F. Posted September 28, 2019 Anybody know the front and rear axle sizes of a 2017 450 FE? I’m starting to look around for a set of a SM wheels/tires Share this post Link to post Share on other sites
zibbit u2 Posted September 28, 2019 (edited) I believe (but, I'm not positive) your front is 22mm and rear is 20mm due to the hardware associated with the axle. Easiest way confirm, is to pull your axle and measure. Edited September 28, 2019 by zibbit u2 Share this post Link to post Share on other sites
