Jalopnik points to an auction on EBay of a biodiesel powered motorbike. The Royal Enfield 350cc diesel motorcycle was imported to the US from India and then converted to run on biodiesel before seeing duty as a demo bike for the concept. It gets around 200 miles to the gallon, though it’s more of an around town potterer than a grand touring or racing bike.
