The Watercross of Texas Rear Sponsons directly bolt-on in place of the OEM sponson. The backing plate is constructed of 6061-T6 aluminum and the blade itself is made from 535 AL-MAG which is then clear lacquered to prevent corrosion. The WCOT sponson makes a huge improvement in the way the SXR cuts through a turn as well as how it handles in the rough. It is designed for both the recreational rider or closed course racer. This race-proven sponson design significantly improves low and high-speed cornering and adds unmatched straight-line stability.
