What is a suicide clutch?
A suicide clutch is a clutch on some old school choppers and motorcycles, where to disengage the clutch instead of using a hand control on the handle bars, you would pull a handle on the side of the motor to engage and disengage the clutch. So at any real good speed if you weren't paying attention you could commit suicide changing gears ( loose your balance and fall off, ouch owee "road rash")
