The “All New” R&D Kawasaki SX-R Aquavein Intake Grate Kit has been specifically designed and developed to deliver the ultimate handling and speed performance in recreational, offshore, and closed course race conditions. The R&D SX-R Aquavein will deliver super quick acceleration, higher top speed performance and a much smoother and more stable ride over the O.E.M. intake grate. Low speed and high-speed turns are a breeze with great 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 to win countless National and World Championships for over 25 years! Bolt on a R&D Aquavein top loader intake grate and experience why R&D is the top selling intake system worldwide.
R&D’s professionally tuned ECU programs offer raised RPM limit settings, advanced ignition timing, and re-calibrated fuel maps all custom tailored to give the Kawasaki SX-R a “wake-up call” with snappier throttle response, much quicker acceleration, stronger mid range pull, and also increases top end speed performance. The Ignition timing in each R&D reprogram is developed to safely maximize horsepower performance with specific fuel octane ratings. R&D strongly suggests that AFR tuning be periodically verified using AEM or Innovate Products also available from R&D. Send your ECU to R&D today and give your SX-R the ultimate BOOST in performance with R&D’s ECU reprogramming. *Part # 801-01501 R&D SX-R R1 ECU; Reprogrammed SX-R ECU to allow up to 8650 RPM’s.

The R&D Offshore Program was used in the 2017 Mark Hahn 300 by Team Go Fast Us / Pastorello, won 1st and 2nd in class. Team Go Fast Us / Pastorello completed 22 laps “WIDE OPEN” for 6 hours equaling 220 miles during the event! Reliable for sure!
R&D Ultra Forged Racing Piston Kits have been developed for the race enthusiasts or precision engine builders who look to gain maximum horsepower from their racing engines using higher compression ratios. R&D offers high quality forged aluminum, heat treated, and CNC machined racing pistons in 10.6-1 (OEM), 12.5-1, 14-1 and super aggressive 15-1 compression ratios. Forged and CNC Machined pistons in High Performance marine applications are a must. Trust the pros at R&D with all your compression ratio, boost, and engine management needs or questions.
Note: R&D/CP pistons will work in all Kawasaki 15F/SXR1500 Engines
• Direct replacement piston kits for High H.P. applications • High quality forged materials replace low performance cast • Improved ring seal with Premium ring sets • Increased RPM’s and horsepower by reducing weight • Compression Ratio Adjustable using R&D Racing Head Gaskets
R&D/CP (for OEM bore) Pt. # 431-35106 for 10.6-1 compression, OEM Replacement (4 Piston Kit) Pt. # 431-35125 for 12.5-1 compression (4 Piston Kit) Pt. # 431-35140 for 14-1 compression (4 Piston Kit) Pt. # 431-35150 for 15-1 compression (4 Piston Kit)
The R&D Power Collector was developed to directly replace the low performance O.E.M. Kawasaki 4 into 2 into 1 Exhaust header collector with a modern “Racing Design” The R&D 4-1 Collector has a much larger area change and volume in the collector over the stock restrictive design. The headers primary tube lengths are changed to allow the header to work harder to better scavenge the cylinders exhaust pressures and gases. The R&D Power Collector design allows Higher Compression Ratio’s and Camshaft Kits to work to their Full Potential by getting rid of restrictions (allowing the engine to breathe), and having a Power Tuned design that will work hard to scavenge the cylinder as well as have a stronger and better tuned exhaust pressure wave timing. significantly increasing and broadened the torque curve with greater RPM carry over, or over run. The R&D Collector will allow aggressive camshaft LSA packages to work like never before on the Kawasaki 1500 engine! If you plan on building an OPEN CLASS race engine with higher compression ratios, The Power Collector is 100% water jacketed and handcrafted using only the best stainless materials! Dyno Testing was performed by Factory Kawasaki on their Super Flow Dyno. Install the Power Collector on a ported head, with R&D camshafts, and a ported exhaust, and get 190-200 H.P. (50 HP over stock) R&D Also offers the Power Collector with V-Band Collared connectors for Turbo Charged Applications!

The new R&D Kawasaki SX-R Pro Series “Race” Billet Sponson Kit was tested and developed specifically for the hard core “Closed Course” Racer who demands the ultimate level of handling and speed performance for the SX-R in aggressive racing conditions. The R&D Pro Series Sponson will carve tighter turns and work extremely well in High Speed two buoy sweeper situations, and also deliver aggressive slalom type characteristics needed for setting up and attempting that sneaky “Inside Pass” on a competitor. The Pro Series RACE Sponson Kit has been extensively race track tested with the Worlds Fastest Pros, to arrive at a setting that is “Race Ready” and eagerly waiting to Win a World Title! Team Pastorello’s Jean Baptiste Botti and Raphael Mauren used the R&D Recreational/Offshore sponson design to win the recent Mark Hahn 300 offshore race! Now they will use the “RACE” Sponson for Aggressive Closed Course racing. Build your confidence like the Pro’s with the Pro Series RACE Sponson kit.
The R&D SXR 2.250” High Flow Rear Exhaust Kit is a “Must Have” kit for better Holeshot and Top End Performance! The high flow kit is designed to be used with High Performance power adders like camshaft kits, and 14-1 Piston kits. the kit also comes complete with a guide fixture needed to cut and gut out the stock restrictive water box. R&D has chosen to modify the stock water box, and maintain the oem exhaust routing to keep water out of the engine in case there is that occasional tip over or rollover, your engine will not get “Swamped” with water that can be catastrophic! The R&D High Flow Exhaust Kit will add a great look and performance muscle sound to the SXR while maintaining a safe sound level under IJSBA and Coast Guard approved 86db. The kits exhaust outlet flange is available in four anodized colors, red, black, green, and clear. Specify color when ordering. NOTE: The R&D Kit is available in two performance options, One for Modified waterboxes, and one designed specifically for the stock waterbox where rules restrictions require stock water boxes (Like Limited or Superstock Classes).
