There's a group of folks called The Crucible, building all sorts of neat stuff out in Oakland, California. It looks like they've put together a biodiesel motorcycle with a couple of goals in mind. They want to promote the use of biodiesel and other bio fuels but they also want to set a new land speed record for diesel motorcycles, currently a mere 105 mph.
This custom has a hand built frame, a BMW swingarm, possibly a BMW fork and a custom aluminum fairing that looks like it one of the old dustbin fairings we used to see.
The engine is from a BMW 320D. It's a 4 cylinder, 4 valve turbo diesel with a displacement of 1995cc. Power output is 163 horsepower and 251 foot pounds of torque. The engine can run on diesel, B99 biodiesel or straight vegetable oil. The whole bike weighs in at a rather hefty 1100 pounds, no small part of that probably due to the engine itself.
They plan to take it to Bonneville this year to see what they can do. Since the bike has already run over 120 mph, a new record seems likely. I would expect diesel motorcycle records to start falling with some regularity since there has been some interesting work going on with diesels, but this one looks pretty neat for a small group of builders.
