$this->bbcode_second_pass_quote('The_Toecutter', 'P')roblem is finding a powerful enough diesel engine that isn't too heavy for a bike. I'd want at least 100 horsepower for every 600 pounds of bike...
Oh, and an interesting article on a diesel motorcycle:
http://www.evworld.com/view.cfm?section=article&storyid=901105 mph top speed and 110 mpg.
Needs more engine. Not powerful enough. GREAT fuel economy though, but has more to do with low weight and good aerodynamics than with engine size. I'm sure a larger diesel engine that would allow it to hit 200 mph would still allow 90-100 mpg if driven normally.
Well personally I don't know any diesel bike that goes much more than 100 miles per hour - it's in the nature of the diesel engine that the output goes into torque and not rpm (yes transformation, but only so much?)... but that also means that you almost literally can climb up vertical hills!
A big problem of the diesel engine is also the vibrations, you must make sure that the frame can take it... I don't think a bigger engine helps here...
As for a good engine, check out the German Hatz Diesel, they used it in this bike:
