The 250 XCF-W has a DDS (damped diaphragm steel) design with a wear-resistant clutch basket, which has been revised for MY 2015 for weight saving, and operates with a diaphragm spring. The basket is machined from high-tensile steel in one piece together with the primary drive gear. This process provides unbeatable reliability and contributes to the narrow engine width thanks to its compact rivet-less design, as well as thin steel linings that assist with the compact clutch dimensions. The diaphragm spring makes it possible to implement an additional rubber damping system inside the clutch hub that offers reliability for the transmission and good traction. This, combined with the hydraulic clutch mechanism by Brembo, provides a very light operation and good controllable modulation of the clutch.
