The DDS platform has been battle-tested at the highest levels of professional motorcycle racing, making it one of the most trusted aftermarket shock absorbers available for Superbike-class machines. Unlike mass-produced OEM replacements, each unit is built to tolerances that translate directly into more predictable handling, reduced rider fatigue and improved lap times.\u003c\/p\u003e\u003ch2\u003eThe ByPass Valve Advantage\u003c\/h2\u003e\u003cp\u003eThe BPV system is the defining feature that separates the DDS Pro from conventional shock absorbers. By independently controlling the damping force at low shaft speeds — precisely where small surface irregularities are absorbed and tyre contact patch pressure is determined — the BPV dramatically improves feedback through the seat and footpegs. The result is a shock that feels compliant and communicative on fractured road surfaces while remaining firmly controlled under hard cornering loads.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis unit (part number 255-017-010-020) is a direct fitment for the following Aprilia RSV4 variants:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eRSV4 1000 RF (2017–2019)\u003c\/li\u003e\n\u003cli\u003eRSV4 1000 RR (2017–2020)\u003c\/li\u003e\n\u003cli\u003eRSV4 1100 (2021–2024)\u003c\/li\u003e\n\u003cli\u003eRSV4 1100 Factory (2019–2024)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInstallation note: K-Tech recommends fitment by an authorised K-Tech Service Centre.
