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.

Adjustable rear master cylinder spacing to allow wide range of compatibility.

Please note that this part may not be a direct replacement of your stock rear master cylinder and may need some custom adjustments to make it fit.

Made in Japan.
