Pro Circuit’s Shift Shaft Brace for your 2013-2021 CRF110F is a part that sits behind the shift lever to offer protection to the shift shaft, preventing it from bending. Please note, the plastic countershaft sprocket will need to be cut to fit this item properly. Once cut, this item will do an excellent job giving the shift shaft support. It is always better to prepare for the unexpected, especially since the shift shaft sticks out and is known to bend.
