This is the Team Orion CRF 5-Port Factory Tuned .21 Buggy Engine. Orion has taken the CRF World Champion Engine technology to the next level. Using patented ABI technology, these are the most efficient and most powerful engines ever produced by Orion. It has never been easier to choose the right Orion engine for your needs.
Thanks to small reinforcements and structural changes in several areas, the engine's crankcase is stiffer in extreme high temperature situations. This provides consistent driving characteristics throughout the whole race and allows the engine to deliver maximum power even in the hottest conditions.
To further improve the top speed of the engine Orion has improved the crankshaft design. The SG type crankshaft with advanced, patented CRF technology is now even lighter allowing the engine to rev up even more!
Thanks to the material used for the piston Orion has been able to tease even more power out of the engines. This material is stronger as well, ensuring incredible reliability in the toughest racing conditions.
The heat sink has a unique hole configuration. Groups of smaller holes combined with milled areas provide improved heat dissipation while remaining light weight.
The engine construction results in better mileage providing an advantage over the competition. You need fewer pit stops, allowing a more flexible pit strategy.
