Full Range of Motion

The SX can rotate 360° which allows orientation to achieve a smaller profile and maximum protection. The unique through bolt design can be tightened independent of the valve body, allowing for a simple installation that easily avoids obstructions.

Innovative Lever Design

The new ergonomic control lever makes the valve easier to operate, even in tight spaces. It features the same tried and true secure locking mechanism as our original valves, but now remains parallel to the body in the closed position for a reduced profile. A lever clip comes standard with the SX for an additional level of security.

No Adapters

The versatility of the SX-series valve allows installation without an adapter on some cars and trucks that may have previously required one.

Made in Japan

The SX is proudly made by the same ISO-9001 certified factory that has been manufacturing Fumoto Oil Drain Valves for more than 35 years.


The BSX is available for most Harley Davidson, 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.
