Increase the performance of your Yamaha YZF-R1 (2015-2026) with the K-Tech DDS Closed Cartridge Kit (+10mm). This Direct Damping System (DDS) was specifically developed for the stock fork and delivers precise damping control under extreme conditions. The kit uses a pressurized system with a 20mm piston that enables high oil flow through the 31mm control piston, significantly improving response and rider feedback.
With the +10mm extended top caps and 30 clicks of compression adjustment, the DDS ensures exceptionally stable performance.
