Original equipment HONDA 2019 11mm Bore Master Cylinder Upgrade for use on 2007 and newer Yamaha YZ & YZF models when running MOTO STUFF Works Edition Caliper. Works with the stock Yamaa line. 

HONDA uses a unique ball and socket internal linkage design that provides a silky smooth feel compared to the inconsistent ratchety feel that other designs provide after a few hours of use.

Also fits all 1996 and Newer HONDA CR & CRF 125/250/450R models.

Honda does not offer this as a complete assembly, so we buy the necessary components and assemble them so they are ready to install.

This is also a nice upgrade on 2006 and newer SUZUKI, KAWASAKI and YAMAHA models with the stock caliper if you want to improve the feel and power of the front brake. Works with the stock lines on all Japanese models.
