These sponsons are a first of its kind. JCRACING incorporated the rear sponson that includes a backing plate base sponson for added stability at high speeds with a mid sponson for unbeatable grip throughout the corner. This sponson is the best of both worlds; stable, yet will turn on a dime when needed. Best of all, these sponsons can be configured to be race legal per the IJSBA and UIM rulebook. These sponsons will provide both the average recreational rider and the world class professional the confidence they are seeking to push this new 1500 to its limits while creating the desired comfortable and predictable ride.
