DescriptionThe whole story▼

Smooth, consistent fork action is the foundation of everyday confidence on the Yamaha YZF-R6 RJ27, whether you are navigating city traffic or pushing on a favourite B-road. The K-Tech GBS-015 slider bush kit is a direct OEM-replacement set machined from hardened steel with copper undercoating and PTFE-treated contact surfaces — a straightforward, cost-effective way to restore or upgrade fork performance without overhauling the entire front end.

Key Features

  • Direct replacement for the standard fork slider bushes on the Yamaha YZF-R6 RJ27 (2017–2026) — no modification required
  • Hardened steel construction with copper coating resists wear far longer than soft OEM bushes under daily use
  • PTFE-coated contact faces reduce sliding friction to a minimum, restoring responsive, stiction-free fork movement
  • Improved fork stability under braking and cornering, sharpening the steering feel you rely on in traffic and on tour
  • Complete set of 2 bushes supplied — everything needed for a full, balanced replacement on both fork legs
  • Precision dimensions (43.00 mm inner diameter × 48.00 mm outer diameter × 12.00 mm height) ensure a snug, rattle-free fit

Build Quality and Everyday Performance

Unlike standard OEM bushes, which are often made from softer materials that wear and introduce play over time, the K-Tech GBS-015 uses hardened steel as the base material. The copper undercoat acts as a sacrificial layer, absorbing micro-impacts and protecting the steel substrate, while the PTFE outer coating keeps friction at bay through the full range of fork travel. The result is fork action that feels noticeably smoother from the first ride — less stiction on initial movement, more consistent damping response, and a front end that tracks true under hard braking.

For R6 owners who cover regular road miles, worn slider bushes are one of the most overlooked causes of vague steering and fork harshness. Fitting this kit as a scheduled maintenance item is one of the highest-value suspension improvements available, restoring the precise handling the RJ27 was designed to deliver.

Fitment and Compatibility

This kit is engineered exclusively for the Yamaha YZF-R6 RJ27 produced between 2017 and 2026. It is not compatible with earlier R6 generations. Installation requires specialist fork tools and should be carried out by an authorised K-Tech service centre or a qualified suspension technician to ensure correct fitment and safe operation.
