R&D 250X / 260X RIDE PLATE



The R&D Kawasaki Ultra 250X Ride Plate has been fashioned after our dominant and championship winning GP-1200R and Kawasaki 15-F ride plate designs with a few new tricks added. The Ultra 250 ride plate is extended 30mm and re-angled over stock to reduce porpoising while the new R&D stepper concept will add top speed. R&D’s Ride Plate concepts are the only aftermarket designs to dominate in Offshore, National, and World Championships, and to be used and endorsed by Factory Yamaha and Kawasaki racing teams for nearly a decade! The new Ultra 250X ride plate from R&D is “The Perfect Ride plate” with a great balance of speed and handling with no compromises!
