K-Tech Shock Absorber Service Kit – Yamaha YZF-R1 RN32, RN49 & RN65 (2015–2026) 205-200-020

Keeping your Yamaha YZF-R1's rear suspension in peak working order doesn't have to mean expensive workshop bills or lengthy downtime. The K-Tech shock absorber service kit 205-200-020 puts every essential seal and hardware component in one box, so a full, professional-grade service of the rear damper becomes a straightforward job rather than a parts-hunt. Designed specifically for the RN32, RN49 and RN65 chassis covering model years 2015 to 2026, this kit delivers genuine long-term value for road riders and track-day regulars alike.

Key Features

• Complete service solution — one part number covers every consumable needed to rebuild the rear shock to factory specification.
• Precision oil seal prevents fluid migration and keeps damping force consistent across the full stroke.
• Dust seal shields the piston rod from road grit, moisture and track debris, extending service intervals.
• Piston rod bush ensures smooth, low-friction travel and accurate damping response mile after mile.
• High-quality O-rings maintain internal pressure integrity for lasting seal reliability.
• New piston rod lock nut included, restoring correct preload retention after every service.

What's in the Kit

K-Tech has specified this kit so that nothing needs to be sourced separately. The five components below represent the complete consumable set for a thorough shock rebuild:

• Oil seal — reliably prevents oil leakage from the damper body
• Dust seal — guards against dirt and debris ingress onto the piston rod
• Piston rod bush — supports smooth, precise damping action
• O-rings — premium seals rated for maximum durability under repeated compression cycles
• New piston rod lock nut — restores safe retention of the piston rod assembly post-service

Build Quality & Performance

K-Tech is a respected name in suspension engineering, supplying components to professional race teams and demanding road riders around the world. Every part in this kit is manufactured to the same tolerances as K-Tech's own damper assemblies, so you're not fitting generic aftermarket seals — you're restoring the shock to the standard it was built to. The inner diameter of 40.00 mm and outer diameter of 14.00 mm are matched precisely to the YZF-R1 damper bore and piston rod dimensions across all three chassis generations covered.

Installation Advice

Shock absorber servicing requires specialist tools and a working knowledge of suspension hydraulics. K-Tech strongly recommends that this kit is fitted by an authorised K-Tech Service Centre to ensure correct assembly, optimal performance and continued safety. Attempting installation without the appropriate tooling risks damaging the new seals or compromising damper integrity.
