Engine 21 Off-Road 5 Ports NVB 521 Racing

The crankshaft used in the nVision® engines is an all-new development based on the patented CRF technology:

  • Acceleration of the gases due to four angled holes pushing the gas‐mixture directly into the combustion chamber with the effect of g‐forces
  • Conical inserts control the flow of the gases and can be exchanged to change the engine’s feeling and drivability characteristics

The result is: incredible acceleration and top speed and maximum control over the power output characteristics of the engine.
