Specs At A Glance

Good To Know

Q: How do I know the fork seals need replacing? A: Oil streaks on the fork tubes, a dropping oil level, or a soft, inconsistent fork feel usually point to worn seals. Replacing them as a set restores proper damping.

Q: Should both fork legs be resealed at the same time? A: Yes, both legs see the same wear, so replacing seals on both sides keeps damping balanced. This set covers both fork legs.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
