I just recently replaced the steering bearings on my '06 YZ450F do to a failed upper seal allowing water in. Now, after replacing the seal and bearings a few months ago it has happened again. The inner lip of the seal keeps getting torn. WTH?? The worst part is the area of the frame under the bearings is a huge open space and I have a puddle of water at the bottom. Is this just poor design or am I the only one??
