Galespeed Billet Rear Brake Master Cylinder Kit for Yamaha R1 R1M

Based in Japan, Galespeed was founded in 2002, and has been focused since 2009 on creating aftermarket high performance brake systems.

With its 12mm piston, this billet rear master cylinder is designed to match the general racing footpeg to lever ratio. This allows a more sensitive and controllable rear brake feel. Made from 6061 Forged aluminum and heat treated for strength and corrosion resistance.

Includes a 90 degree integrated rear brake reservoir.

This kit includes two extra Y plunger pin brackets to make it compatible with a variety of aftermarket Yamaha R1 / R1M rear sets including the stock rear set.

Made in Japan.
