SJBMW Alpha Racing | RC-STK-S (Carbon)

The advanced STK model offers everything the ambitious track rider needs plus alpha Racing’s Carbon Bodywork Package*. A fully equipped race bike that has everything it needs to roll straight to the starting grid. Due to the selected parts, it is possible to race this bike in nearly every STK series and championship.

* The Carbon Package wraps the bike in high-quality carbon. All bodywork components are replaced by aerodynamically optimized prepreg carbon parts. The perfect weight-to-strength ratio ensures increased protection for parts that are sensitive to falls, as well as increased performance thanks to the weight savings.

All SJBMW alpha Racing Bikes includes the SJBMW alpha Racing Setup Package. This setup package includes an individually tailored race bike and an introduction to the software management of the M Race Calibration Kit. Personal training to the extensive motorsport kit electronics (M RCK) as well as a mapping individually tailored to the rider. In addition, the suspension elements and the ride height are adjusted in-house at SJBMW by our Performance Suspension Tuning Professionals to the rider’s needs.

Run-in Service

Before delivery every race bike is given an extensive run-in process for the new engine and subsequent performance measurement on the dynamometer. In addition, after the running-in process, the running-in engine oil is exchanged for a fully synthetic engine oil recommended by BMW Motorrad and the oil filter is renewed. A check of the gearbox ensures that the gear shift function is working properly.

  • Engine run-in process
  • Dynamometer performance measurement
  • Oil and oil filter change
  • Gearbox check


Please Note

  • Racetrack bike, not for road use
  • Race bike by alpha Racing, not a BMW Motorrad vehicle
