I realize drag racing is not a big thing here but hopefully there are a few who will appreciate this effort. I have a much longer thread with more details at vintagehondatwins.com so this is a synopsis in pictures. If anyone is interested in seeing the full thread it's here: https://www.vintagehondatwins.com/f...)-Budget-drag-bike-project-DOHC-450-of-course
At first I considered using a CB360 swingarm for the extra 2" of wheelbase it offered, but it required opening the axle slots for the larger rear axle. Then this happened
I was given a CB650C after the salvage yard took what they wanted from it.
Weirdly modified 450 swingarm on top of the CB650 swingarm, which is much beefier and longer allowing the use of much stouter parts - bigger axle, sprocket drive flange and wider 16" Comstar wheel
