Billet Reservoir Caps for Vmax using XJR Master Cylinders

This a pair of CNC machined billet aluminium Reservoir Caps for the Yamaha Vmax that has had the brakes upgraded to include XJR master cylinders. They are precision engineered, and not to be confused with the many caps on the market which are just cast ones that have been polished up and have a design printed on the top. The 'Vmax' is engraved into the top, and the finish is as it comes off the machine, enabling you to then have it polished or anodised to taste. Also comes complete with four stainless screws (not shown) to replace the original. Please email any questions to
