The system is a development of a similar kit it has been making for mountain bikes.
Power is taken from the existing motorcycle sprocket shaft, and transferred by chain and shaft to a pair of contra-rotating drive shafts aligned with the fork legs. These transfer power to the front wheel and the company claims the contra-rotation removes torque-steer.
Christini claims the system is rapidly adapted to new models and will inevitably see use on road bikes. It has recently raced a Honda CRF250 in a local enduro, and placed second.
Two-wheel-drive has been tried in a variety of forms over the years. Yamaha is the only mainstream motorcycle company to put it into production, adapting an hydraulic version to one of its dirt bikes. The company is known to have tried 2WD road prototypes, though one has yet to make it into production.
Advocates say it has huge advantages in slippery conditions, proving more grip and confidence. See www.christini.com.
