American Made

The EFM Auto Clutch is proudly made in American and we offer a LIFETIME WARRANTY on the parts that we manufacture. We do not guarantee the clutch plates, only the parts we make. Please call for further details.

Lifetime Warranty

The EFM No-Stall Auto Clutch comes with a life time warranty material and workmanship.


Our clutches are based on engine RPM so they react to throttle input, not bike movement. This allows for instant lockup on any bike and unsurpassed holding power. Bottom line: Faster application and MORE POWER!

Better Ride

The EFM Auto Clutch allows the rider to take off and stop simply by using the throttle and with out touching the clutch lever. Smooth acceleration and stopping with out the worry of stalling the motorcycle.
