Pair of black rubber fork oil seals sized 38 x 50 x 10.5 mm for front forks. Designed to prevent oil leakage and help retain correct damping and handling.
Prevent Oil Leakage – with a precision rubber sealing lip sized 38 x 50 x 10.5 mm
A close-fitting rubber lip surrounds the fork tube and blocks oil from escaping, using the specified 38 mm inner, 50 mm outer and 10.5 mm height dimensions to match the shaft and housing. Correct sealing keeps oil where it belongs during compression and rebound strokes.
Keeps fork oil contained to avoid messy leaks and preserve clean fork internals, so damping remains consistent ride after ride.
Restore Fork Damping – thanks to retained oil levels and clean internals
By preventing oil loss and reducing contamination, hydraulic damping characteristics remain stable, preserving the designed compression and rebound behaviour of the front suspension. Proper seal fit prevents air ingress that can degrade damping.
Delivers more predictable handling and a firmer front end by maintaining the fluid volume and condition required for correct fork performance.
Quick Maintenance Swap – with matched pair supply and direct-fit sizing
Supplied as a pair of identical black rubber units, the seals match the stated 38 x 50 x 10.5 mm dimensions for direct replacement on compatible forks. The front fork seal sits at the top of the slider and is replaced during a fork strip-and-service.
Allows a single maintenance session to reseal both forks, cutting workshop time and returning the bike to service quickly.
