SHOWA Fork Cartridge Rod Seal (Ø12.5 mm rod) for KAWASAKI KXF 250, HONDA CRF 250 and SUZUKI RMZ 250, RMZ 450 2010-2020

The SHOWA (tige Ø12.5 mm) SHO-3001003 fork cartridge rod seal is designed for SUZUKI RMZ 250, RMZ 450, HONDA CRF 250 and KAWASAKI KXF 250 from 2010 to 2020. In a cartridge fork, the damping happens inside a closed tube in which a piston rod slides. This seal keeps the oil in around the rod: once it wears, oil gets past and the damping loses effectiveness and consistency.

Fitting tips

1. Servicing a cartridge takes method and the right tools: follow the fork manual or leave it to a suspension specialist.
2. Strip the cartridge, clean all the parts and check the condition of the rod (scratches, pitting).
3. Fit the new part, oiled, without twisting it or damaging it on the threads.
4. Reassemble with fresh fork oil and carefully bleed the air out of the cartridge.

Why SHOWA?

Showa was founded in 1938 in Gyoda, Japan, as Showa Aircraft Precision Works. After the war, the company put its aeronautical know-how to work on motorcycle suspension, notably for Honda, and the brand now belongs to the Astemo group, formed by a merger completed in January 2021.
