Parts/Kit Overview

The R&D Kawasaki SXR 800 Performer Kit was developed to improve overall handling significantly, and increase the entire power range with safe and reliable bolt on parts. All of the accessories listed in the Performer kit install easily and will perform well on their own individually. The R&D Performer Kit has been rigorously tested and has proven to be a true weekend warrior kit! The R&D Performer Kit will run reliably and detonation free on 92-Octane rump gasoline.

  • The R&D Kawasaki SXR 800 Ride Plate was developed in conjunction with the Factory Kawasaki race team to produce a product that could go to the winner’s circle in both limited and pro super-stock classes! The ride plate has also proven itself to be a favorite! The R&D Plate is extended over stock to reduce porpoising, increase high speed stability, and has the factory rectangle slot for maximum traction.

  • The R&D Kawasaki SXR 800 Aquavein gets a grip on the water with two patented scoop veins to load plenty of water into the Kawasaki pump! R&D’s exclusive patented technology has been used by Factory Kawasaki for many years to dominate in Pro stand up classes! No other intake grate performs better than the Aquavein on an SXR 800!

  • The R&D Pump Shoe Sealer Kit will completely fill the large molding voids in the O.E.M. intake shoe and match up to fill the large gap between the O.E.M. pump shoe and the pump housing. The R&D precision molded Pump Shoe Seal Kit is manufactured from high grade PVC rubber, installs easily, and will help reduce pump cavitation.

  • The R&D Timing Advancer Kit was developed to relocate the O.E.M. pulsar coil located inside the flywheel cover. The R&D Advancer Plate Kit advances the entire ignition map 6 degrees, which will produce more horsepower throughout the entire RPM range! The R&D Timing Advancer Kit is backed by 2 National and 2 World Championships in the pro limited class. The R&D Timing Advancer Kit posts identical peak horsepower dyno numbers compared to expensive aftermarket igniters.

  • The R&D Pro Series Head Kit was developed to raise the engine’s compression ratio to safe levels more reliably and economically. Cylinder heads machined out of precision cast aluminum have proven on the dyno to have much less heat and detonation over expensive billet heads! When comparing price, performance, and reliability, cast heads win every time! The R&D Heads incorporate “O” ringed design, and are girdle kit optional. Part # 411-75000

  • The R&D Power Plenum Filter Kit was developed to replace the restrictive O.E.M. filter box with a high performance design that will have zero air flow restriction! The R&D Power Plenum Kit is complete with C.N.C. machined billet velocity stack adaptors, which incorporate the pro-lock design! The R&D Power Plenum Kit adds to low-end acceleration, and installs easily.

  • R&D/Solas 13/22 Dynafly Impeller will reduce cavitation, and add to top speed performance.

  • The R&D SXR 800 Handle Pole Spring Kit incorporates an industry first design, which allows the handle pole spring tension to be adjusted to suit any type of riding style. For example, multi-time National and World Champion Jeff Jacobs prefers less spring tension in rough water conditions, and more spring tension in flat water conditions. The R&D adjustable Handle Pole Spring Kit will work with any aftermarket handle pole utilizing the O.E.M. spring. Billet aluminum construction, anodized for corrosion resistance, and installs easily in minutes.

  • The R&D SXR 800 Rapid Ratio Steering Plate was designed to increase steering nozzle turning ratio with three adjustable steering cable ball pivot positions (Stock, plus 8 mm, and plus 16 mm). The R&D Steering Plate also has a redesigned stop system, which will allow the steering plate to be relocated 1” forward. NOTE: Must use the R&D twin position sub-plate position for 1” relocation capabilities. Part # 521-80020

NOTE: Internal carburetor rejetting is not necessary with the Kawasaki SXR 800 Performer Kit, unless a Factory Pipe Exhaust System is installed, the Factory Pipe carburetor jetting specs will work great!

NOTE: To achieve the peak RPM and peak speed posted in the information categories, it will be necessary to bore the O.E.M. reduction nozzle plus 1 to 2 mm. Most recreational riders and pro limited racers bore the reduction nozzle more than 2 mm to gain more low-end acceleration.
