After David Ronnefalk’s victory at the World Championships in Las Vegas, we are pleased to present the brand new WC edition CRF .21 3 Ports Factory RS V3 engine!
As all the other CRF engines also the WC edition features the patented CRF crankshaft (PAT EP 1 787 018) with a compressor-like technology. However this is the first Team Orion CRF engine which comes with a DLC treated, black crankshaft (Diamond-like carbon) for approved durability! Compared to the standard RS engine this model comes with a modified crankcase and tuned sleeve. All this gives you a different feeling with smoother response and higher mid-range and top speed. Also the mileage could be improved.
The WC edition engine comes with a Ceramic high quality bearing and is available world-wide by now!
Front Bearing: 7x19x6mm Swiss
Rear Bearing: 14.2×25.3×6.3mm Ceramic
Crankshaft: Balanced SG shaft
Carburetor: Aluminum 2 needles
