Cobra ECX 50 ATV Key Features

Cobra Friction Drive (CFD)
Did you ever wonder why a 50cc motocrosser has beefier transmission gears than a typical 450F? Why does a typical seven year-old break more chains in a year than a seasoned pro? Do you feel that you spend more time and money on items such as clutch baskets and primary gears than you think you should? Well, at Cobra we have asked the same questions, and with our patent pending Cobra Friction Drive (CFD), we’ve done something about it!

The Cobra Friction Drive is one of the most innovative pieces of technology to come around in 50cc racing since Cobra first introduced the modern 3-shoe clutch a decade ago. Its operating principal is simple: The CFD adds some ‘give’ to the driveline system. Unlike any other type of motorcycle transmission, when a centrifugal clutch (used on all 50cc motocrossers) is locked up, the entire powertrain…everything from the rear wheel to the crankshaft…is also locked. Now imagine landing off a big jump with the throttle pinned. The engine is spinning at close to 15,000rpm, and then SLAM, the rear wheel comes to almost a dead stop as it hits the ground. With very little give in the system, this results in brutal wear and tear on many components such as the crankshaft, clutch basket, clutch shoes, transmission gears, transmission bearings, chain, sprockets, and rear wheel. It’s no coincidence that many of the items that you replace and repair often are on the aforementioned list.

So how does the CFD work? 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 The primary gear, instead of being one solid part, has been replaced by a clutch that is set to disengage at a pre-determined torque level.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.

So what does this mean on and off the racetrack?
  • More time riding and less time doing maintenance!
  • Durability improvements in all driveline components.
  • Longer clutch shoe life.
  • Reduced weight and friction in the engine’s final drive and more power to the ground.
  • The freedom to aggressively throttle away from heavy landings without having to worry about things breaking.
  • Overall reduced cost of ownership!
