K-Tech TRDS-R Shock Absorber Yamaha YZF-R1/M RN32, RN49, RN65 (2015-2026) 261-015-270-020

Engineered for riders who demand podium-level suspension without the complexity of an external reservoir, the K-Tech TRDS-R shock absorber delivers all-day comfort and precision on both the circuit and the road. Purpose-built for the Yamaha YZF-R1/M across the RN32, RN49 and RN65 generations (2015–2026), this unit combines K-Tech's Through-Rod technology with an intuitive adjustment philosophy that keeps you focused on riding, not on setting-up.

Key Features

• Through-Rod Damper System (TRDS) eliminates the need for an external reservoir, reducing bulk and improving heat dissipation for consistent, fade-free performance across long stints
• The 'R' stands for Regulation — a high-precision adjustment architecture designed to help riders at all sponsorship levels reduce lap times through repeatable, confidence-inspiring tuning
• 18-click compression and 18-click rebound circuits (suggested baseline) give technicians and self-supported riders a wide, clearly defined adjustment range
• Compact, self-contained design integrates cleanly with the YZF-R1/M's chassis without modification, retaining the factory aesthetic
• Race-proven at the highest levels of competition, including the British Superbike Championship and the Isle of Man TT
• RCU adjustment travel of 4.00 mm enables ultra-fine ride-height and geometry changes to suit circuit or road use

Through-Rod Technology — Why It Matters

Conventional twin-tube shock absorbers rely on an external reservoir to manage fluid displacement and heat. K-Tech's Through-Rod design handles both tasks internally: the through-rod displaces fluid mechanically, removing the need for a separate canister while simultaneously improving thermal regulation. The result is a shock that stays cooler for longer, maintaining consistent damping characteristics whether you are completing a timed flying lap or covering distance on a long ride.

Precision Adjustment for Every Rider

The TRDS-R was conceived with championship-level regulations in mind. Where cost-cap rules or restricted technical support might otherwise disadvantage a privateer, the straightforward click-adjustment system allows a single technician — or the rider themselves — to make meaningful, trackside changes with confidence. Suggested starting settings of 18 compression clicks, 18 rebound clicks and 12 mm of preload provide an accessible baseline from which to build, while the 4.00 mm RCU travel fine-tunes geometry precisely.

Fitment & Compatibility

This shock absorber is a direct fitment for the following Yamaha models:

• Yamaha YZF-R1 RN32 (2015–2016)
• Yamaha YZF-R1M RN32 (2015–2016)
• Yamaha YZF-R1 RN49 (2017–2020)
• Yamaha YZF-R1M RN49 (2017–2020)
• Yamaha YZF-R1 RN65 (2020–2026)
• Yamaha YZF-R1M RN65 (2020–2026)

Installation by an authorised K-Tech Service Centre is recommended to ensure correct spring pre-load setup and damping baseline calibration.
