DescriptionThe whole story

Engineered specifically for the Yamaha YZF-R3 (2015–2018), the K-Tech GBS-005 fork slider bush kit is built from hardened steel with copper and PTFE coatings — a combination that sets it apart from standard OEM replacements in both longevity and feel. If smooth, precise fork action matters to you, the quality of the bushings inside that fork leg is where it starts.

Key Features

  • Hardened steel construction with a copper coating for outstanding resistance to wear and corrosion
  • PTFE-coated contact surfaces dramatically reduce friction, delivering noticeably smoother fork travel and more precise front-end feel
  • Manufactured to exact OEM dimensions — 41.00 mm inner diameter, 45.00 mm outer diameter, 12.00 mm height, 2.00 mm wall thickness
  • Direct, precise fitment for the Yamaha YZF-R3 (2015–2018) with no modification required
  • Kit includes two bushings — everything needed to refresh both fork legs in a single purchase

Construction and Performance

The GBS-005 uses a hardened steel core that withstands the sustained side-loading a fork bushing endures through cornering, braking and road imperfections. The copper intermediate layer provides an additional barrier against corrosion and helps the PTFE outer surface bond durably through repeated fork cycles. That PTFE coating is the critical detail: by minimising metal-to-metal contact, it keeps stiction low across the full range of fork travel — the difference is most apparent in low-speed, small-amplitude movements like corner entry and trail-braking where a sticky fork hurts confidence most.

Fitment and Compatibility

These bushings are designed exclusively for the Yamaha YZF-R3 produced between 2015 and 2018. They are not a universal part. Installation requires fork disassembly and the appropriate workshop tooling; K-Tech recommends fitting by an authorised K-Tech Service Centre to ensure correct assembly and sustained fork performance.
