when you give your bike the gas your clutch is going to slip excessivly, new or used, the lockout will eliminate this slipping and in the process transfer more of the engines horsepower to the rear wheels instead of it being lost through a slipping clutch. The lockout can also extend the life of your clutch 2 to 3 times and remove the need to use stiff springs.The lockout has six weighted fingers surrounding its perimiter that apply progressivly more force to the pressure plate as the RPM's of the engine increase,it is this force on the pressure plate that will eliminate your clutch from slipping.
