Why Choose This Complete Fork Rebuild Kit?
A basic fork service normally replaces the oil and seals, but worn guide and slide bushes can still cause excess play, increased friction and reduced suspension performance. This complete rebuild kit replaces the major wear components together, helping restore smooth fork operation, improve front-end feel and extend the service life of your KYB 48mm forks. With K-Tech seals, bushes and fork oil included, everything is supplied in one convenient package.
Frequently Asked Questions
Does this kit rebuild both fork legs?
Yes. The kit includes two K-Tech Fork Seal Kits, K-Tech guide bushes, K-Tech slide bushes and 1 litre of K-Tech 5W Fork Oil for servicing both fork legs.
Will this fit my motorcycle?
This kit is designed for the Yamaha, Kawasaki, Triumph and Suzuki models listed above that are fitted with compatible KYB 48mm front forks.
What is the difference between a fork service kit and a complete rebuild kit?
A standard fork service kit normally includes fork seals and oil. This complete rebuild kit also includes the guide and slide bushes, making it suitable for a full fork overhaul where the main wear components are being renewed.
When should fork bushes be replaced?
Fork bushes should be inspected during servicing and replaced if there is visible coating wear, excessive play or increased friction. Worn bushes can reduce fork sensitivity and accelerate wear to other suspension components.
