Worn fork bushes are one of the most overlooked causes of vague, notchy steering — the K-Tech SBS-003 slide bush kit restores the precise, smooth action your Yamaha YZF-R3 deserves, without the cost of a full suspension rebuild. Engineered as a direct OEM replacement for the 2019–2026 YZF-R3, this kit gives everyday riders a straightforward path to better front-end feel and longer fork service life.
Key Features
- Direct OEM-replacement fit for the Yamaha YZF-R3 (2019–2026) — no modification required
- Hardened steel shell with copper coating for exceptional wear resistance under repeated fork cycles
- PTFE-coated contact surfaces dramatically reduce sliding friction, restoring smooth, responsive fork action
- Precise machined dimensions (35.70 mm ID / 37.70 mm OD / 20.00 mm height / 1.00 mm wall) ensure correct clearance and zero slop
- Kit includes both slide bushes — everything needed to complete the job in one purchase
Built to Last Longer Than Stock
K-Tech's choice of hardened steel over standard OEM materials is deliberate: the substrate resists deformation under load, while the copper interlayer bonds tightly to the steel and provides a sacrificial wear surface. The outer PTFE coating takes friction management a step further, allowing the fork tube to glide through the bush with minimal resistance even when the fork oil is cold and the bike has been sitting overnight. The practical result is consistent steering feel from the first corner of every ride — a benefit that commuters and weekend road riders notice immediately.
Precision Dimensions, Correct Clearance
At 35.70 mm inner diameter, 37.70 mm outer diameter, 20.00 mm height and 1.00 mm wall thickness, the SBS-003 reproduces the OEM geometry exactly. Correct clearance between the fork tube and outer tube is critical: too tight and the fork binds; too loose and the tube rocks, accelerating seal wear and degrading handling. These K-Tech bushes sit right in the middle of the specified tolerance window, giving the fork seals the stable, concentric environment they need to last.
Fitment & Compatibility
The K-Tech SBS-003 is designed exclusively for the following model:
- Yamaha YZF-R3 — model years 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026
This kit is not compatible with any other model year or variant. Always confirm your year before ordering.
Installation requires specialist tools and fork-service knowledge. K-Tech recommends fitting be carried out by an authorised K-Tech service centre to ensure correct seating and maximum safety.
