This is a 80's style brake master cylinder with matching clutch lever and mirror mount perch set. You can use it on any single or dual disc brake bike you want. Perfect for 80's bikes where you want to replace the bars and need a new master cylinder that doesn't have an angled reservoir.

This master cylinder has a brake light switch with two small spade connectors just like many of the 80's Honda's, it is attached to the bottom of the master cylinder.

For those of you who have rebuilt a master cylinder that's seized up after sitting for 30 years, we don't have to tell you how much time you'll save buying a new master cylinder!

This does not come with instructions, so please be informed about how to install a new master cylinder, or have a professional do it.

For use with M10 x 1.25 banjo bolt. Standard size for most all Honda, Yamaha, Kawasaki and Suzuki's.

The mirror mount threading fits standard 10MM mirrors.

15.8mm (5/8") piston bore size.
