Having issues with brake fading? Our rear brake reservoir cooling extension screws into your rear brake master cylinder to allow for more volume for brake fluid, which results in a temperature drop that gives you much better response from your rear brake in hotter conditions. We offer rear brake reservoir cooling extensions that fit a number of different motocross, enduro and supermoto models such as KTM, Husqvarna, Husaberg and Sherco.
