The one and only SPORT CHOCK is a unique, patented wheel chock designed with the sport bike enthusiast in mind. It's designed to fit a 120/70 - 17' front tire but will work with 110mm or 16' tires found on some sport bikes, and also on larger bikes like the Triumph Rocket III. This is a simple, lightweight chock that will securely hold your sport bike upright by simply riding or pushing the bike into the chock. While great for transporting your bike, the Sport Chock is also great for performing maintenance or for storing your bike securely when not in use. With its sturdy, lightweight (21 lb.) steel construction and beautiful and durable powder coat finish, the Sport Chock will provide years of dependable and good looking service. It has a small footprint and will fit conveniently anywhere and can be transported easily. For Racers this is the perfect stand to leave in the pits so you can ride in and get off your race bike. No more fumbling around for your rear stand or having someone get one for you. Once you've used it and experienced the convenience and security, you'll wonder how you got along without it.
