AWD provides greater control over wet roots and slippery rocks. The rear wheel simply will not slip without transferring some of the power to front wheel. The AWD system is so efficient, it is hard to tell whether it is working… until you need it.
You will be able to descend with confidence and corner more aggressively due to increased front wheel grip. Pedaling, shifting and braking are just like on a traditional bike. When the clutch is engaged, the rear spiral gear interlocks with the rear hub and power is transferred via internal shafts to the forward spiral gear set, which drives the CHRISTINI freehub.
Due to a slight gearing differential, the front wheel is not actively powered on smooth level ground. However, the moment the rear wheel slips, power is instantaneously transferred to the front wheel. We realized that every other motorcycle we've ridden hard constantly exceeds available traction, tearing up trails and shredding rear tires. Christini claims that rear tires last more than twice as long on an AWD bike. The AWD system comes with some disadvantages, starting with 13 extra pounds.
It takes more effort to loft the front wheel because the extra weight of the AWD system sits ahead of the countershaft sprocket. And the system adds complexity to the bike: There are three more chains and several more gears, though Christini includes a grease gun with purchase and Zerk grease fittings make it easy to keep everything running smoothly. During our factory tour last year, we saw that the quality of the AWD parts is top-notch and the additional complexity is more than offset by the bike's on-trail competence.
Whether you're roosting your friends on a rocky uphill climb or riding happily through deep sand, AWD makes it easier to go fast or slowly off-road. Type keyword s to search. Today's Top Stories.

As the power is transferred to the front wheel, it becomes easier for the rear wheel to find traction which in turn allows the rear to grab traction and move the bike forward again. The front then releases and you are instantly rear wheel drive again. When you ride the Christini you will be amazed at how easy it is to find traction, and how much energy you conserve compared to a conventional motorcycle.
There is no energy-robbing hydraulics involved. The light weight all-mechanical system works similar to that of AWD systems found on four wheeled vehicles. The use of one-way clutches in the front hub allows the front wheel to be driven at a slightly slower rate than the rear wheel.
Power is transferred to the front wheel only when the rear wheel loses traction or the front wheel skids. The front-to-rear power ratio is adjustable with a simple sprocket adjustment. This allows for nearly unlimited fine tuning of the AWD system to suit riding conditions and personal riding preference.
See how this works in our AWD Tech section. The whole system is easily maintained using standard tools that you already have in your tool box.
