Here in the Unites States, riding motorcycles is more likely to be for pleasure than for practical purposes, but that is not the case in all areas of the world. A group from Australia is proving the worth of their biodiesel-powered motorcycle by showcasing in alongside other alternative-fueled vehicles taking part in special classes during the running of the World Solar Challenge. The bike, known as BioBike
, uses a Yanmar 400c diesel engine running on biodiesel through a CVT transmission. No gears to shift on this bike, and the high torque output likely makes this a relaxed rider. The frame is a modified Husaberg unit, meaning that it's chock-full of high tech and high-priced parts, including the suspension components -- which is good considering that the machine is a bit heavier than the donor bike. Although there are no plans to offer the bike commercially, the amount of interest shown might prove the concept viable.
