DescriptionThe whole story

Keeping your Yamaha YZF-R1 M's sophisticated suspension in peak condition demands precision-grade components — and this K-Tech shock absorber service kit delivers exactly that. Designed exclusively for the M-variants of the RN32, RN49 and RN65, it contains every seal, bush and fastener required to restore the original damper to factory specification, giving you back the all-day ride comfort and confident handling that made the R1 M a benchmark supersport machine.

Key Features

  • Complete service solution in a single kit — no hunting for individual seals or sourcing mismatched components
  • Oil seal prevents fluid loss and maintains consistent damping force across all riding conditions
  • Dust seal blocks dirt, grit and moisture from contaminating the damper internals
  • Piston rod bush ensures smooth, precise piston movement for accurate, fatigue-free damping response
  • High-quality O-rings provide reliable, long-lasting sealing throughout the service interval
  • New piston rod retaining nut included for added security after reassembly

Build Quality & Performance

K-Tech has built its reputation supplying suspension components to World Superbike and British Superbike teams, and that commitment to material quality flows directly into their service kit range. Each component is manufactured to tight tolerances — the 42.00 mm inner diameter and 14.00 mm outer diameter specifications are held precisely so that rebuilt dampers restore the original stroke feel rather than merely approximating it. The result is a shock absorber that moves with the same progressive, controlled character that Yamaha engineered into the R1 M's Öhlins-sourced electronics-controlled suspension system.

Road & Track Suitability

Whether the R1 M sees demanding back-road touring or regular track days, a correctly serviced rear shock is fundamental to both comfort over long distances and confidence under braking and mid-corner. Worn seals allow oil to bypass the piston, degrading both high- and low-speed damping and introducing unpredictable chassis behaviour. Replacing these components at the recommended interval restores the precise, adjustable platform that the R1 M platform is built around.

Installation Note

K-Tech recommends that this service kit is fitted exclusively by an authorised K-Tech Service Centre. Specialist tooling and technical expertise are required to ensure optimum damper performance and maximum safety after reassembly.
