Mechanical Function
Type 1 (cruiser)
This product is used to lock the throttle on a motorcycle. The usual way of riding a motorcycle requires the rider to hold the throttle on at all times to accelerate. This can lead to fatigue on long trips. This product uses a metal clamp with a plastic washer to hold the throttle in the on position while letting the rider relax his hand. There is a small spring and plastic switch for functionality and when the switch is turned off, it quickly allows the throttle to go to zero.
Type 2 (sport bike)
This product serves the same purpose as the cruiser type throttle lock. This products different in how it accomplishes the task. The sport bike throttle lock is located on the outside of the throttle (directly to the right of one's right hand). It takes the place of the right hand end weight that sport bikes have. In order to "lock" the throttle the rider must turn the large nut on the throttle lock in the same direction as the accelerator. This will cause the nut to press against a washer which then presses against the motorcycle's throttle. The added friction from the washer being tightened by the left hand nut causes the throttle to be held in place. Unlike the cruiser style lock, this product does not have a "quick" release feature like some of its competing products. The user must manually tighten and loosen the throttle lock. It is possible to move the throttle while the throttle lock is engaged so long as it has not been over tighten. Although there is no quick release, this product is a very simple and effective cruise control for sport motorcycles.
