Fumoto® BSX Series for Motorcycles

Fumoto® BSX-Series Engine Oil Drain Valves

The new BSX series of valves takes the best of our SX series and puts it in a smaller envelope for motorcycles and other small engines. The BSX-Series is the latest in engine oil drain valve innovation from Fumoto, designed with motorcycle owners in mind. It combines the compact design of the SX-Series with a sleek new look that is perfect for space-limited oil drain locations, such as those found on motorcycles.

BSX has the Features You Want

Available for Almost any Ride

The BSX-Series is available for most Kawasaki, Honda, Yamaha, and Suzuki motorcycle engines. To find the specific valve for your application select your make year and model with our product search.

Simple to Install, Effortless to Use

The BSX-Series uses the same trademarked technology that allows all Fumoto valves to go on quick, and last throughout a lifetime of use.

With the 360° rotation feature, a design that originated at Fumoto with the SX-Series, obstructions do not prevent installation and the valve can be oriented in any direction.
