The new R&D Kawasaki Ultra 300X Aquavein Intake Grate Kit has been designed and developed to deliver the ultimate handling and speed performance in recreational, offshore, and closed course race conditions. The R&D Ultra 300X Aquavein will deliver quicker acceleration, higher top speed performance and a much smoother and more predictable ride over the O.E.M. intake grate. Low speed and high-speed turns are a breeze with new found control. The R&D design offers a smoother “recreational friendly” off throttle deceleration allowing a more comfortable and smoother ride. The secret to the R&D Aquavein’s hook up performance is in its patented, award winning, and championship winning wing and twin bar, super 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!
