K-Tech TRDS-R Shock Absorber Yamaha YZF-R6 RJ27 (2017–2026) 261-017-270-010

The K-Tech TRDS-R shock absorber brings championship-proven rear suspension technology to the Yamaha YZF-R6 RJ27, covering model years 2017 through 2026. Trusted at the highest levels of circuit racing — including British Superbike and the Isle of Man TT — this unit is built to exacting standards that demand consistent, repeatable performance under the most gruelling competition conditions.

Key Features

• Through-Rod Damper System (TRDS) technology delivers extraordinarily precise, adjustable damping — giving riders and technicians a transparent, accurate picture of chassis behaviour at every corner.
• The 'R' designation stands for Regulation, making this shock absorber fully compliant with championship cost-cap rules and relaxed racing regulations, so you can run it with complete confidence in scrutineering.
• Compact, reservoir-free design eliminates external plumbing and reduces unsprung weight without sacrificing thermal performance.
• Enhanced heat dissipation maintains consistent damping characteristics across extended race stints — no fade, no drift, no compromise late in the race.
• Compression and rebound adjustability (12 clicks each, as recommended) allows precise set-up to suit track surface, tyre compound and rider preference.
• Used at the very top of British and international racing, validating the engineering integrity of every unit that leaves the K-Tech facility.

Through-Rod Technology & Performance

Unlike conventional twin-tube or monotube designs, K-Tech's Through-Rod architecture passes the damper rod completely through the shock body. This produces an almost perfectly balanced hydraulic system, reducing the pressure differential that typically causes inconsistency under hard braking and aggressive acceleration. For a machine as sensitive as the YZF-R6, that consistency translates directly into corner-entry confidence and earlier, cleaner drive.

The absence of an external reservoir keeps the unit tidy within the R6's tail section, simplifying installation and reducing the risk of damage in competition. Heat generated during aggressive riding is managed through the unit's internal geometry rather than an add-on canister, keeping the centre of gravity low and the set-up clean.

Regulation-Compliant Racing Specification

The TRDS-R was conceived specifically for riders and teams operating under current championship price-restriction regulations or in classes that enforce relaxed technical rules. Rather than compromising on engineering, K-Tech engineered a unit that meets those financial boundaries while delivering damping performance that stands up to comparison with unrestricted hardware. Whether you are contesting a national superstock series or preparing for a road race, this shock absorber removes any regulatory concern from your technical preparation.

Fitment & Compatibility

This shock absorber is designed as a direct fitment for the following motorcycle:

• Yamaha YZF-R6 RJ27 — model years 2017 to 2026

Installation by an authorised K-Tech Service Centre is recommended to ensure correct spring preload, damping settings and top-mount torque are set before the unit enters service.
