Helmet Guardian Premium Helmet Security Lock
The Helmet Guardian consists of a pair of high quality helmet locks attached to a steel plate, pre-drilled with slots to line up with most license plates in the US and Canada. The locks and steel plate are powder coated to a nice black finish. The overall width of this great accessory is 11 inches, and the locks are 2 1/2 inches tall. It can be installed in either the upper or lower two license plate bolts, where the license attaches to the bike. Also included is a package of theft deterrent fasteners, to detract would be thieves.
A really nice feature of this product is that both locks are keyed alike, and they are spring loaded, so you do not need to fumble with a key when trying to lock up your helmet by the D ring. The fit is universal, and it fits quite nicely between the panniers or saddle bags most adventure bikes, cruisers, touring, and sport bikes.
