Ken's Long Fork Chopper 

Heres the nitty gtitty:
Frame: Honda CB450k with a custom hardtail, no neck modifications.
Motor: Honda Xl250
Fork: 6 Foot rigid fork, Xl250 Triple tree
It has a total length of slightly over 10 feet, and a top speed of 60mph (unconfirmed)
As of this date, I have put about 6 miles on this bike, and it makes me feel like I am truly flying every time.
