This was built using a 1985 Harley Davidson FXR. Basically the frame and a few small parts are all that is left. This bike was built by a local bike builder here in Central Florida. He built it for himself about a year and a half ago.He put about 2000 miles on it. Motor is a new Gen II Rev Tech 100 with an added performance cam. Transmission is a Rev Tech 5 Spd. Has a Primo Rivera Clutch with a Heavy Duty Diaphragm. PM brakes front and Rear, JB Forward Controls, JB Hand Controls and Dual Front Rotors made to look like the original. Bike has 42 degree Rake and 11 ½ inch Struts just like the original. Correct Seat Pan and Seat just like the original. I have the original rare Rick Doss single mirror like the original. You can see it in one of the pictures. I changed to old school 3 inch round mirrors for better visibility. If your looking at this you can see the serious detail put into this bike. When you fire it up, this bike sounds just like it does in the movie. It is a blast to ride and needless to say, it is very fast.
