Kawasaki Ultra 310, 300 & 250 Performance Parts
Parts for the Kawasaki Ultra 310R, 310X, 310LX (2014–2026), Ultra 300X/LX (2011–2013), Ultra 250X/260X (2007–2010) and the naturally aspirated Ultra LX. Every supercharged Ultra runs the 1,498cc four-cylinder with a factory supercharger; the Ultra LX runs the same engine without it.
That engine is shared with the SX-R 1500 and STX-15F, so pistons, rods, cams, valves, injectors, starters and cooling parts cross-fit all three. Supercharger, intercooler and hull parts are Ultra-specific.
What's in this collection
- Supercharger & intake: supercharger impellers, drive components, intercooler and intake parts for the 310/300/250
- Engine internals: APE, Carrillo and OEM pistons, rods, valves, guides, springs and gaskets for the 1500
- Pump & driveline: Solas impellers, pump components, wear rings and cooling
- Electrical & sensors: OEM and FuelTech harnesses, sensors, batteries and starters
- ECU tuning: mail-in ECU reflash for the Ultra 310 (RTD remote tuning is not available for Kawasaki)
Built on the 1500
We race the Kawasaki 1500 in stand-up competition and build the same engine in supercharged form for the Ultra. For a stock 310, start with the Ultra 310 ECU tune, then intake and supercharger upgrades. Tell us your year and mods before you order and we'll confirm fitment.
