BMW S1000RR
The BMW S1000RR Motorcycle was originally released in 2009. It is a 999cc four cylinder engine making 180-200hp depending on the model year. There have been a few changes over the years, but the general architecture remains the same.
Model years vary in their engine configuration somewhat:
- 2009-2014 models used virtually the same engine, sensors, etc.
- 2015-2018 had some minor engine updates, put out a little more power.
- 2019 had entirely new engine that is more compact and has dual camshaft profiles that can be switched (similar to Honda VTEC).
2009-2018 Engine Configuration
- 999cc four cylinder engine with 4 valves per cylinder
- 4x individual smart coil on plug ignition
- 8x injectors with one set at the ports, one set in the airbox firing into the trumpets
- Dual position variable length runner intake manifold with an actuator that changes between two different trumpet lengths
- Electronic throttle (different between 2009-2014 and 2015-2019, -2014 has cables going to TPS mounted on throttles, 2015-2018 has no cables and has encoder on throttle control)
- Two VR sensors are used for engine sensing, one on crank one on exhaust camshaft
- Crank uses a 60-2 trigger wheel
- Camshaft has a single tooth wheel
- Quickshift strain gauge sensor in the linkage allowing the ECU to sense shift forces
- 2x Variable Exhaust Actuators (not documented here)
