K-Tech DDS Closed Cartridge Kit for Yamaha YZF-R7 (2021–2025) - Maximum control and performance for the street and race track
The K-Tech DDS (Direct Damping System) Closed Cartridge Kit was specifically for the original fork of the Yamaha YZF-R7 (21–25) developed. This state -of -the -art damping system uses a 20 mm piston that ensures an improved oil flow through the 31 mm control valves and thus enables precise and sensitive damping control.
The patented DDS design prevents cavitation and guarantees constant performance even under extreme conditions. The independently working damping circles (asymmetrical system) increase the dynamics and improve the response time. The system keeps a spring force stable and reliably at all times.
Product highlights:
- 30-fold-adjustable compression and rebound in damping For optimal adaptation
- 18 mm preloading For individual fine -tuning
- DDS technology For constant damping in all driving situations
- 8 mm piston rod To reduce the system offset
- 20 mm piston For improved oil flow and higher damping control
- 31 mm control piston For a better driving experience and faster response behavior
- Patented design To remove cavitation
- Increased hub Compared to the original cartridge
- Racing sports: Used in the British Superbike and the Isle of Man TT
Scope of delivery:
- 3 pairs of feathers for individual coordination
- Special tools for easy change
