June 29, 2008 Yamaha is developing a CVT (Constantly Variable Transmission) version of its enduro machinery according to recent patent applications with the United States Patent and Trademark Office. Conceived by Leonardo da Vinci 500 years ago, the CVT provides an automatic gearbox with an infinite number of gears, smoother and more effective power delivery, greater reliability, and less fuel consumption and its power delivery characteristics could well be a boon in slippery off-road conditions, particularly with some help from a computer. The CVT's biggest advantage is ensuring the motor is always running “in the power band” and as the infinitely variable gear ratios change, it should deliver one smooth rush of power from standstill to top speed.

No details are available on the size of the powerplants, but alongside Yamaha’s 2WD developments, there’s no doubt the traditional dirt bike is set for some evolution in the next few years.
