Parts/Kit Overview

The R&D Kawasaki 1200 STXR stage 2 kit is the answer for significantly improved acceleration and top speed performance over the R&D stage 1 kit! The addition of the M-16 reed valve kit and 46mm Mikuni carburetors add more low and midrange horsepower! If you are looking for more top speed performance, check out the R & D stage 3 and stage 4 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 High Performance 42 cc o-ringed cylinder head kit will add significant low and mid range acceleration, and a much needed increased top speed performance.

  • The R&D STXR 1200 Plenum Filter Kit was developed exclusively with factory Kawasaki to have maximum airflow performance and install easily with Factory triple pipes! Factory pipes require the special and unique design and shape the R&D filter offers to produce 250 plus horsepower!

  • The R&D STXR 1200 M-16 Reed Valve and intake manifold kit and R&D triple 46mm Mikuni carburetor kit will add a substantial increase in acceleration and overall horsepower! Top speed will increase with the 150-200 RPM gain! Stage 2 kit with 46mm carbs is 91 octane safe!

  • 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 2 kit runs on 91 octane fuel! Slight carburetor tuning will be necessary!
