2006 Cobra ECX50 User Ratings

So how does the CFD work on the EXC50? It’s very simple, actually. The primary gear, instead of being one solid part, has been replaced by a clutch that is set to disengage at a pre-determined torque level. This break-away torque is several times the maximum engine torque (so it never slips when the engine is driving it), however, when it receives a high load in the other direction it spins providing a cushioning effect on many expensive engine and driveline components.
