R&D Ultra 250 | 260 Performer Kit
R&D Ultra 250 | 260 Performer Kit
The R&D 2007-2008 Kawasaki Ultra 250X Performer Kit was developed to improve overall handling, reduce pump cavitation, and increase top speed performance with strictly bolt on performance parts without engine modifications! The entire Performer Kit installs quickly and very easily with basic instructions and hand tools. Each component part in the Performer Kit can be used as a stand alone product delivering the performance gains individually charted above. The new 2007-2008 Kawasaki Ultra 250X engine platform is significantly different over previous Kawasaki models with its new roots type supercharger. The new supercharged Kawasaki engine is a fantastic power plant; however the 950-1000 pound weigh-in without a fuel load has left the engineers at R&D a big challenge to work with. The R&D Performer Kit will add a noticeable 4-5 mph increase in top speed performance with superb handling benefits. The R&D Performer Kit will transform a great boat into “The Perfect Boat”. The R&D Performer Kit parts have been offshore endurance and closed course race tested and have chocked up some impressive wins in the 2007 season as well as world championships in the stock 4-stroke runabout class at the world finals.

R&D ULTRA 250 PRO SERIES SPONSON KIT
R&D ULTRA 250 PRO SERIES SPONSON KIT
The new R&D Kawasaki Ultra 250 Pro Series Sponson Kit was designed and developed with all new generation performance concepts in mind to deliver a whole new level of handling and speed performance with offshore and closed course race proven adjustability options. The R&D Pro Series Sponson Kits have been extensively offshore, race track, and 1 and 2 up recreational tested to guarantee a comfortable setting for any riding style or condition! The R&D Ultra 250 Sponson Kit will deliver higher top speed performance and a much smoother and more predictable ride over O.E.M. sponsons. Low speed and high-speed turns are a breeze with new found control. The secret to R&D’s new generation concept is in the backing plate design with an aftermarket first, low pressure, low friction concept that breaks up and relieves speed robbing drag within the sponson’s backing plate channel. The new R&D design staggers the sponson blades fins water trapping area to pick up less water in the front and more in the back. The stagger/step-up concept greatly reduces chine walk in high speed corners, while allowing more rear end grip. There is also a higher end recreational/race setting with enough grip for the best of pro’s! Finally there is an aftermarket sponson kit that really does it all! More top speed due to less drag, less chine walking, racer preferred rear end grip, and unmatched straight line stability.
