Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

What should I check before fitting the YZ-S4F?

Confirm the YZ-870C mounting points and shock lengths match your existing hardware, and verify the 13mm OD and 10mm ID dimensions to ensure compatibility with your pistons and seals.

Can I anodise or change the finish?

Surface finishing can be done, but use compatible coatings and avoid altering critical sealing faces. Any finishing should be undertaken by a specialist to preserve tolerances.

Is this suitable for club racing?

Yes. The YZ-S4F provides consistent shock performance that helps maintain repeatable handling, which is useful when refining setups for competitive club racing.

How often should I inspect these shock bodies?

Inspect externally after heavy runs and service shocks regularly. Look for scoring, deformation or seal wear and replace components as needed to keep damping consistent.
