The new R&D Kawasaki Ultra 250 Aquavein Intake Grate Kit has been designed and developed with all new performance concepts in mind to deliver the ultimate handling and speed performance in recreational, offshore, and closed course race conditions. The new R&D Ultra 250 Aquavein has been extensively offshore, race track, and 1 and 2 up recreational tested to guarantee reduced cavitation and maximum pump hook up in any condition. The R&D Ultra 250 Aquavein will deliver quicker acceleration, higher top speed performance and a much smoother and more predictable ride over the O.E.M. intake grate in rough water conditions. Low speed and high-speed turns are a breeze with new found control. The secret to the R&D Aquavein’s performance is in its patented, award winning, and championship winning wing and twin bar, deep channel design. The well proven R&D top loader Aquavein wing concept has been used exclusively by Factory Kawasaki and Yamaha racing teams to win every Pro 1200 and Open World Championship for a full decade!
