The Basics of AWD
Christini’s patented mechanical All Wheel Drive system delivers power from the motorcycle transmission to the front wheel through a series of chains and shafts. There is no energy-robbing hydraulics involved.
The lightweight all-mechanical system works similar to that of AWD systems found on four wheeled vehicles. The AWD system (powering the front wheel) is driven at a slightly lower rate than the rear wheel (approximately 80%). Under optimum traction conditions, the rear wheel is actually driving faster than the front AWD system. One-way clutches within the front hub allow the front wheel to freewheel under these conditions. At this point, the AWD system is effectively passive. Though the front AWD system is turning, it is not actually transferring power to the front wheel. When the rear wheel loses traction, the drive ratio, relative to your forward speed, changes. The AWD system engages, transferring power to the front wheel until traction is reestablished at the rear wheel.
The way the front system works is like pedaling a bicycle down hill. You are pedaling, but because of gravity (acting like the rear drive) the bike is traveling faster than you are delivering power. When you get to the bottom of the hill and slow down (similar to what happens when the rear wheel spins), you will begin to power the bike again.
An added benefit of AWD is that the front wheel does not want to wash out. When a front end tucks, the wheel stalls, stops turning, and begins to push. With the AWD system, as soon as the wheel begins to stall, power is delivered to the front wheel, forcing it to turn. With the front wheel under power, it is nearly impossible to wash out the front end.
