K-Tech DDS Closed Cartridge Kit – Aprilia RSV4/RF/1100 Factory (2017–2026) 155-017-010-020

Engineered for riders who demand precision from their Öhlins-forked Aprilia, the K-Tech DDS Closed Cartridge Kit transforms the front-end behaviour of the RSV4 1000 RF (2017–2019) and RSV4 1100 Factory (2019–2026) into something markedly more responsive, composed and consistent. The distinctive K-Tech Direct Damping System heritage is expressed here in every machined detail — a design philosophy refined through years of world-class racing that now finds its way onto road and track alike.

Key Features

• Direct Damping System (DDS) architecture delivers immediate, linear damping response with none of the lag associated with conventional cartridge designs.
• 20 mm piston paired with a 31 mm control piston maximises oil flow and damping precision across the full range of fork travel.
• Patented anti-cavitation design maintains oil consistency under sustained hard braking and high-frequency track inputs, preventing instability caused by aerated fluid.
• Asymmetric system configuration optimises dynamic balance between compression and rebound, tailoring feel to the RSV4's aggressive geometry.
• Part number 155-017-010-020 is a direct fitment for Öhlins-forked variants — no modifications required.
• Factory-suggested baseline settings allow immediate, informed setup straight from the box, with extensive adjustment range to suit individual rider preference.

Design, Finish and Heritage

K-Tech Suspension has built its reputation on the race paddock floors of British Superbikes, the Isle of Man TT and World Superbike — and that racing provenance is embedded in the DDS Closed Cartridge Kit's design language. The close-tolerance machining, the considered asymmetric layout and the anti-cavitation chamber are not afterthoughts; they are the result of a development programme carried out under the harshest competitive conditions. This is a product that looks and feels like the precision instrument it is, worthy of the Aprilia RSV4's own championship-winning bloodline.

Performance on Road and Track

Fitting the DDS Closed Cartridge Kit to an RSV4 running the standard Öhlins fork immediately unlocks a level of front-end feedback the original internals cannot match. The 20 mm piston and enlarged 31 mm control piston together allow a greater volume of oil to move freely through the system, translating into a fork that tracks surface irregularities accurately rather than skipping over them. On track, the anti-cavitation patent pays dividends under repeated, late-braking events — oil remains homogeneous and damping curves stay predictable lap after lap. The suggested baseline of 16 compression clicks, 18 rebound clicks and 10 mm preload provides a neutral starting point from which riders and technicians can dial the setup toward their preferred balance of comfort and control.

Fitment and Compatibility

This kit is designed specifically for Aprilia models equipped with Öhlins forks:

• Aprilia RSV4 1000 RF — model years 2017, 2018, 2019
• Aprilia RSV4 1100 Factory — model years 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026

Always verify the fork manufacturer on your specific machine before ordering. This kit is not suitable for non-Öhlins fork variants of the RSV4 range.
