Öhlins TTX 25 Cartridge Kit FKR 132 
Yamaha YZF-R9 (2025)

The racing inspired FKR cartridge kit has technology derived straight from the Moto3, Moto 2 and World Superbike championships developed by our engineers in Sweden and is designed for high end racing.

The FKR Cartridge kit features a spring pressurized system, compared to the old gas pressurized system, the spring pressure offers a more simplistic and user friendly design that also accounts for easier maintenance. But there are more advantages of a spring pressurized system. There is no risk of gas leakage, it also gives a more consistent performance curve and allows for a more compact design. With the Öhlins TTX technology, a new designed piston and an 8mm piston shaft we reduce the pressure build-up and create a faster damping response. That gives a “linear” style of damping characteristics which create more tuning options and also increases grip and bump absorption properties while improving chassis stability.
