DescriptionThe whole story

Keep your Yamaha YZF-R6 RJ27's rear shock performing to the standard it left the factory with. The K-Tech shock absorber service kit 205-200-020 is engineered specifically for the RJ27 generation (2017–2026), supplying every critical sealing and guidance component needed for a professional-grade rebuild — with safety at the centre of every part included.

Key Features

  • Complete seal and hardware kit designed specifically for the Yamaha YZF-R6 RJ27 shock absorber — no guesswork, no mismatched parts.
  • Oil seal ensures a fully leak-free closure of the shock body, maintaining correct damping fluid pressure over thousands of kilometres.
  • Dust seal shields internal components from road grit, water and contamination that accelerate wear and compromise safety.
  • Piston rod bush provides precise, rattle-free guidance of the rod throughout the full stroke, preserving consistent damping response.
  • High-quality O-rings deliver reliable sealing across all internal joints for a rebuild that meets OEM-equivalent standards.
  • New locking nut included for reassembly, eliminating the risk of reusing a fatigued fastener and ensuring structural integrity under load.

Built for Professional Service Standards

K-Tech has developed this kit with the same precision that underpins their suspension components used in WorldSBK and BSB competition. Every seal, bush and O-ring is manufactured to exact tolerances so that, once installed, the shock returns to its intended damping characteristics rather than approximating them. Using manufacturer-specified replacement parts rather than generic equivalents means service intervals are upheld correctly and the component can be signed off with confidence.

The inclusion of a fresh locking nut is a detail worth noting: it reflects K-Tech's understanding that safety-critical fasteners should never be reused after full disassembly. It is a small addition that makes a meaningful difference to the integrity of the finished rebuild.

Installation & Safety Notice

Fitting this kit requires specialist workshop tools and a thorough understanding of suspension rebuild procedures. K-Tech strongly recommends that the service is carried out by an authorised K-Tech Service Centre. Correct installation is essential not only for optimal performance but for the safety of the rider — a shock absorber that is incorrectly assembled poses a serious hazard on both road and track. Please do not attempt this service without the appropriate equipment and technical knowledge.
