22-025   4-piston caliper
<< Back 

The 22-025 4-piston caliper comes with many different bolt patterns. You can use it as either a single or double configuration up front, or also as a rear brake on for example custom bikes or choppers.

When used as a single caliper we recommend a 14 mm diameter master cylinder, with 2 calipers you should go with our 17.5 mm master cylinder.

The 22-025 series is probably one of the most cost effective performance choices available on the street bike market.
