Team Orion CRF 21 & Alpha Discovery engine
Having shown the first image of the new competition CRF 5-port engine only yesterday, Team Orion have released the full features and spec list of this latest addition to their line of CRF competition engines. The motor features a CRF crankshaft with angled gas channel and external slots as well as a high-performance ABC liner and two needle carburetor with aluminium body for improved throttle response characteristics and increased fuel economy. Team Orion have also released details of another new engine, the Alpha Discovery 3.5cc 5-port Low Budget competition engine. With all the great features of a competition engine combined with a low budget price, this turbo plugged motor offers good power and mileage and features a CNC machined lightweight piston and bi-steel competition ball bearings.
