DescriptionThe whole story

When lap times matter, fork precision is non-negotiable. The K-Tech GBS-008 slider bushing kit restores the Yamaha YZF-R6 RJ11 RJ15 fork to factory-spec tolerances — or better — delivering the consistent, friction-free damping response that serious track work demands.

Key Features

  • Hardened steel construction with a copper intermediate layer and PTFE-coated contact surfaces for minimal static and dynamic friction.
  • Precision dimensions — 41.00 mm inner diameter, 43.00 mm outer diameter, 15.00 mm height, 1.00 mm wall thickness — for a drop-in fit with zero play.
  • PTFE coating dramatically reduces stiction through fork stroke, sharpening initial turn-in response and improving mid-corner feedback on both road and circuit.
  • Copper and PTFE layers provide active protection against wear and corrosion, extending service intervals even under sustained high-load track use.
  • Complete kit: two K-Tech fork slider bushings supplied, covering both fork legs in a single purchase.
  • Direct OEM replacement for Yamaha YZF-R6 RJ11 and RJ15 (2005–2016) — no modification required.

Built for the Track, Ready for the Road

The YZF-R6 is a machine that rewards precision, and the front fork is its primary communication channel with the tarmac. Worn slider bushings introduce lateral play in the fork legs, clouding damping feedback and causing uneven pad-to-disc contact under hard braking. The K-Tech GBS-008 kit eliminates that slop, restoring the crisp, progressive fork action the R6 was designed around.

The hardened steel substrate resists deformation under the lateral loads generated during aggressive braking and fast direction changes. The copper layer bonds the PTFE surface evenly across the bushing, while the PTFE itself delivers a self-lubricating interface that keeps friction consistent whether the fork is cold on a morning warm-up lap or heat-soaked after a long race stint.

Professional Installation

Installation requires specialised fork tools and should be carried out by an authorised K-Tech Service Centre. Correct fitment ensures optimal functionality and safety. These bushings are designed exclusively for the Yamaha YZF-R6 RJ11 RJ15 (2005–2016) — do not fit to any other model or year range.
