K-Tech DDS Closed SBK Cartridge Kit for BMW M1000RR K66 (2021–2026) – Ultimate racing performance for road and track
Experience maximum riding precision with the K-Tech DDS (Direct Damping System) Closed SBK Cartridge Kit, developed for the original fork of the BMW M1000RR K66 (21–26). This high-performance damping system uses a 20 mm piston and 31 mm control valves for increased oil flow, enabling precise and sensitive damping adjustment.
The patented DDS design prevents cavitation and ensures consistent stability even under extreme conditions. The independently operating damping circuits (asymmetric system) improve dynamics and shorten response times. A pressurized spring force ensures that the system operates reliably in all riding situations.
⚠️ Important note: This kit is not approved for Superstock 1000 classes (due to the modified travel with 125 mm stroke and +8 mm length).
