DescriptionThe whole story▼
Precision-engineered replacement fork slider bushes for the Yamaha YZF-R3 (2015–2018), the K-Tech SBS-009 kit restores factory fork action with a safety-critical upgrade that exceeds OEM standards. Hardened steel construction, copper undercoat and a PTFE-lined contact surface work together to deliver compliant, controlled front-end behaviour — exactly what you need when ride safety and long-term reliability are the priority.
Key Features
- Direct OEM replacement designed exclusively for the Yamaha YZF-R3 (2015–2018) — guaranteed fitment with no modification required
- Hardened steel core provides a rigid, reliable foundation that resists deformation under hard braking and repeated fork cycling
- Copper coating acts as a protective barrier against corrosion and galvanic wear between dissimilar metals inside the fork leg
- PTFE-lined contact surfaces drastically reduce friction, allowing the fork to respond accurately and consistently to road and track inputs
- Complete kit contains two bushes — everything needed to fully refresh both fork legs in one service
- Manufactured to K-Tech's exacting quality standards, the same brand trusted by professional race teams worldwide
Performance & Build Quality
Fork slider bushes are a safety-critical component. Worn or corroded bushes allow lateral play inside the fork leg, introducing vagueness into the steering and increasing the risk of fork stiction under braking. The K-Tech SBS-009 addresses this directly: the multi-layer construction — hardened steel substrate, copper bonding layer and outer PTFE surface — provides a bearing interface that is both harder-wearing and lower in friction than a standard OEM bush.
The PTFE coating is particularly important for real-world riding. It maintains a consistent coefficient of friction across a wide temperature range, meaning the fork behaves predictably whether you are commuting on cold mornings or pushing hard at the track. The result is sharper turn-in, more progressive braking feedback and a front end that inspires confidence rather than doubt.
Installation Note
These bushes are safety-relevant parts. K-Tech recommends installation by an authorised K-Tech service centre, as specialist tools and technical knowledge are required to ensure correct fitment and to guarantee the performance and safety of the finished assembly.
