K-Tech TRDS-R Closed Cartridge Kit – Aprilia RSV4 / RF / 1100 Factory (2017–2026) 160-017-010-020

The K-Tech TRDS-R Closed Cartridge Kit is a race-pedigreed suspension upgrade built on K-Tech's Through-Rod Damping System technology — a design refined at the British Superbike Championship and the Isle of Man TT. Engineered specifically for the Aprilia RSV4, RSV4 RF, and RSV4 1100 Factory (2017–2026), it replaces the standard open-cartridge internals with a closed-cartridge unit that delivers measurably superior damping consistency and thermal management across every session.

Key Features

• Through-Rod Damping System (TRDS-R) closed cartridge design for a more precise, linear damping response compared with conventional open cartridges
• 36 clicks of independent compression and rebound adjustment — each circuit fully decoupled for granular set-up control
• Enhanced heat dissipation keeps oil temperature stable under sustained track use, maintaining consistent damping force lap after lap
• 18 mm preload adjustment range lets you dial in ride height and spring rate balance without removing the forks
• Race-proven at British Superbike and Isle of Man TT level — trusted by professional and high-level amateur riders alike

Design, Finish and Heritage

K-Tech has spent decades building suspension components at the very top of road racing. The TRDS-R reflects that heritage in every detail: the closed-cartridge architecture draws directly from K-Tech's works-level hardware, sharing the same fundamental geometry and damping philosophy as units seen in the BSB paddock. The finish is precisely machined and the tolerances are held to the exacting standards you would expect from a manufacturer whose products have contested the most demanding circuits in the world. Part number 160-017-010-020 identifies this as the Aprilia-specific variant, dimensioned and valved from the factory for the RSV4 platform rather than being a generic fitment.

Performance on Road and Track

With a 713 mm overall length and 125 mm of travel, the TRDS-R replaces the factory cartridge unit with geometry that mirrors the original fitment — meaning no chassis geometry changes and a straightforward installation path for a qualified technician. The suggested baseline settings of 16 clicks compression and 16 clicks rebound give a neutral starting point from which the full 36-click range can be explored. Whether you are chasing lap times at a track day or tuning out mid-corner instability on a fast road route, the independent circuits mean you are never compromising one setting to correct another.

Important Installation Note

Installation must be carried out by an authorised K-Tech Service Centre. Specialist tools and techniques are required to ensure correct assembly, safe operation, and full performance of the cartridge system. Fitting by an unqualified workshop may void the warranty and compromise safety.
