Yes, because the technology is still in it's infancy, but the major motorcycle company, Yamaha, had been working on prototypes for a couple of years now and the results have supposedly been good so far I think there is also a small company out there that's already selling a conversion kit for a certain dirtbike already. Two wheel drive isn't new in motorcycles. Rokon had been making two wheel drive bikes since the early 70's with a mechanical drive to the front wheel. The bike they made was more of an expeditionary/utility bike and is more for slogging slowly through the wilderness. If Yamaha does push through with 2 wheel drive bikes, I think the armed services and other government departments (Police, DNR, Homeland Security...etc) will be very interested. the niche is certainly there.
