K-Tech DDS Closed Cartridge Kit for Yamaha YZF-R1 RN32, RN49, RN65 (2015–2025) -Maximum damping performance for the racetrack
The K-Tech DDS (Direct Damping System) Closed Cartridge Kit was specifically for the original fork of the Yamaha YZF-R1 (RN32, RN49, RN65) developed. This high-performance damping system uses a 20 mm piston that ensures an increased oil flow through the 31 mm control valves and thus enables precise and constant damping control.
The patented DDS design eliminates cavitation and ensures maximum stability even under the most extreme conditions. The independently working damping circles (asymmetrical system) improve the dynamics and ensure a faster response time. The spring force keeps the system stable and reliable at all times.
Product highlights:
- 30-fold-adjustable compression and rebound in damping For maximum adaptability
