This is a Team Orion CRF .21 US Spec buggy engine. The CRF US Spec is the result of intensive testing with the
collaboration of talented team drivers Ryan Cavalieri, Jorn
Neunmann and Philipp Guschl. With the introduction of new types of cars
with lighter concepts, it appeared that our existing CRF engine was too
powerful! So we have created a new Spec engine that keeps the
incredible torque of the engine but now the power is delivered in a
smoother way as requested by the team. At the same time it has a better
mileage efficiency.
Key Features:
- New crankcase for more power
- New back plate for smoother gas response
- Lightened head
- New generation crankshaft with closer timing, better gas response, smoother power delivery
- New crankshaft coating for longer lifespan
