DescriptionThe whole story

Engineered specifically for the Yamaha YZF-R6 RJ27, the K-Tech SBS-018 slide bushing kit brings race-derived fork precision to one of the most celebrated supersport machines of the modern era. Drawing on K-Tech's long-standing reputation in professional road racing, this kit replaces the standard fork bushings with components built to measurably sharper tolerances — delivering a fork that responds with the immediacy the R6 platform demands.

Key Features

  • Exact-fit replacement designed exclusively for the Yamaha YZF-R6 RJ27 (2017–2026) — no adaptation or modification required
  • Hardened steel construction with a copper undercoat for robust corrosion resistance throughout the service life
  • PTFE-coated contact surfaces minimise sliding friction, sharpening fork response on both road and track
  • Matched inner and outer diameters ensure zero slop and consistent damping behaviour across the full stroke
  • Complete kit supplied as a pair, ready for a single fork rebuild service

Design, Finish and Heritage

K-Tech Suspension has built its name supplying components to World Superbike and British Superbike teams, and that heritage is visible in every detail of the SBS-018. The copper plating is not merely cosmetic — it acts as a sacrificial barrier between the hardened steel body and the aluminium fork tube, preventing galvanic wear that can degrade standard bushings over time. The PTFE coating on the running faces carries the same philosophy: a finish chosen for performance rather than appearance, ensuring the bushing slides cleanly under load from the first kilometre.

The result is a fork that feels noticeably more planted under hard braking into a corner, with a suppleness at low speeds that the OEM bushings struggle to maintain once worn. For R6 riders who use their machine regularly on track days as well as public roads, the difference in front-end communication is immediate and tangible.

Fitment and Compatibility

This kit is manufactured exclusively for the following fitment:

  • Yamaha YZF-R6 RJ27 — model years 2017 to 2026

Do not attempt to fit this kit to any other fork diameter or model variant. Installation must be carried out by an authorised K-Tech Service Centre, as specialist tooling and technical knowledge are required to guarantee optimum performance and safety.
