Kawasaki Jet Ski Performance Parts & ECU Tuning
Every Kawasaki part we carry, in one place: the SX-R 1500 stand-up, the supercharged Ultra 310, the STX 160 and STX-15F, and the two-stroke classics. Most modern Kawasakis share the 1,498cc four-cylinder, naturally aspirated in the SX-R, STX and Ultra LX and supercharged in the Ultra 310, so engine internals, injectors, starters and cooling parts cross-fit across the lineup. Hull parts do not. Pick your series to see what fits:
- Kawasaki SX-R Series: SX-R 1500 (2017+) and SX-R 800 stand-up parts, handlepoles, hull and race components
- Kawasaki Ultra Series: Ultra 310, 300 and 250 supercharger, intake and engine parts
- Kawasaki STX Series: STX 160, STX-15F and STX-12F service and performance parts
- Kawasaki Vintage Legends: two-stroke JS, X2, 750 and 1100 parts
- Fast PowerSports Hulls: GP1R and F16 race hulls built around the Kawasaki 1500
Kawasaki ECU tuning
Kawasaki tuning is mail-in only. We flash the SX-R 1500, GP1R, F16 and STX-15F for stock and modified engines on 93 octane or race fuel, and the Ultra 310 on 93 octane. Ship us the ECU and it comes back flashed, fast, from Florida.
Built on the race course
We race the Kawasaki SX-R 1500 in pro stand-up competition. The parts in these collections are the ones that survive a race season on our own skis, from Worx, WCOT, RIVA, AMF Billet, RRP, APE, Carrillo and OEM. Not sure a part fits your year? Ask before you order and we'll check.
