Parts/Kit Overview

The R&D Kawasaki 1200 STXR Stage 4 Pro Limited Kit is the answer for a limited class winning package! R&D equipped STXRs are the only performance kits available noted to beat or compete with GP 1200 limited's. Significantly improved acceleration and top speed performance over the R&D stage 3 kit. R&D equipped limited's have performed well in pro superstock divisions.

  • The R&D STXR 1200 Ride Plate Kit will increase handling and turning capabilities substantially. Its 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 36 or 38cc O-ringed Cylinder Head Kit will add significant low and mid range acceleration, and a much needed increased top speed performance. Racing fuel will be necessary with higher compression ratios!

  • The R&D STXR 1200 Power Plenum Filter kit was developed exclusively with factory Kawasaki to have maximum airflow performance and install easily with Factory triple pipes!

  • The R&D STXR 1200 Aquavein Pro 2 Intake Grate Kit is necessary for rough water or closed course racing! To win races, the R&D grate is a must have part!

NOTE: The stage 4 kit runs on 105 octane racing fuel! Slight carburetor tuning will be necessary!
