Parts/Kit Overview

The Kawasaki 1200 STXR is a great boat right from the factory! The STX hull has been the basis for Kawasakiís great success in national and world competition! The Ultra 150 1200 cc engine placement in the STX hull has produced an almost unbeatable combination in all-out competition! The Kawasaki 1200 STXR has great handling, great stability and turns very good. However, in the hard-core recreational world it lacks in top speed performance! The R & D stage 1 kit is the answer for significantly improved acceleration and top speed performance! If you are looking for more top speed performance, check out the R & D stage 2 and stage 3 performance packages.

  • The new R&D STXR Aquavein Intake Grate will reduce cavitation while increasing overall handling, straight line stability and top speed performance. The R&D Aquavein Grate will keep the STXR's pump loaded and hooked up, increasing rough water top speed averages 2-3 mph!

  • The R&D STXR 1200 Ride Plate Kit will increase handling and turning capabilities substantially! Itís performance capabilities are backed by back-to-back national and world championships.

  • The R&D STXR 1200 Sponson Kit will increase straight line stability and improve high speed turning capabilities.

  • The R&D STXR 1200 Power Plenum Filter Kit will add increased overall engine performance. Improved acceleration and increased RPMís of 100 plus will add top speed performance. R&D Performance is the only aftermarket company that offers a filter kit for the STXR 1200ís O.E.M. carburetor assembly, contrary to a recent magazine article in Watercraft World.

  • The R&D STXR 1200 Solas 15/21 Concord Impeller will add a top speed performance increase of .5-1 mph. However, the stock STXR 1200 impeller is very good and hard to beat!

NOTE: The stage 1 kit runs on 91 octane fuel! Slight carburetor re-jetting will be necessary!
