Lever Jammer. Lever Jammer is an additional securing device for use when transporting motorcycles, locking the front brake of the bike to prevent potential
movement of the front wheel when on a truck or van. The Lever Jammer, a strong neoprene strap with D-clip, wraps around the throttle grip and closed brake lever and secures fast to keep the lever depressed and front brake locked on. Lever Jammers should be used in conjunction with other securing products such as tie-down straps and shrouds.
