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

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.
