Smooth, precise fork action underpins every aspect of a confident ride, and the K-Tech GBS-018 slider bushing kit delivers exactly that for Aprilia RSV4 and Tuono V4 owners. Engineered to OEM dimensions, this kit replaces worn fork guide bushings with components built for long-term durability and low-friction performance — keeping your front-end feeling planted and responsive mile after mile.
Key Features
- Hardened steel shell with copper coating resists corrosion and handles the sustained loads of road and track riding without premature wear.
- PTFE contact surfaces reduce friction to a minimum, ensuring the fork glides smoothly through its full travel with no stiction or binding.
- Manufactured to exact OEM specifications for a precise, rattle-free fit that restores factory-standard fork geometry.
- Supplied as a pair so you can carry out a complete bushing refresh in one service — no partial replacements, no unbalanced feel.
- Wide fitment coverage spanning Aprilia RSV4 and Tuono V4 models from 2009 through 2026, including APRC, RF, RR, and 1100 Factory variants.
Construction & Performance
The GBS-018 bushings combine a hardened steel body with a copper intermediate layer that distributes load evenly and protects against fretting corrosion where steel-on-steel contact would otherwise accelerate wear. The inner bearing surface carries a PTFE liner that dramatically lowers the coefficient of friction, translating directly into a more supple fork action. Whether you are chasing lap times at the circuit or covering long distances on the road, the result is a front end that tracks accurately and absorbs bumps without the harshness that tired, worn bushings introduce.
