There has always been a "
steampunk" tradition for this type of thing - homebrewed and SLOW AS H-E-double-hockey-sticks. But now there are some real industrial types getting them off the ground building awesome TORQUE-MONSTERS:
Thunder Star 1200 Diesel by
Star Twin
Uses a Euro 3 cylinder VW TDI engine, JAMS with CAD-developed cases and transmission to make the fastest EVER. Sweet. Can you say BIODIESEL motorcycle with 100 mpg and 120 mph top speed? RAD.
Couple other DIESEL bikes that rock:
Neander Turbo 1400

HDT Bulldog

Let the Games begin!
