Re: 69 CB450 from North GA

You might have trouble lining up your sprockets properly with too wide of a wheel. The wheel might end up off center while the sprockets are lined up, or vise versa.. This is just an educated guess on my part after dealing with my own wheel swap on a 450...

I'm not using the swingarm. I just kinda figured it would be a problem that could possibly be solved with spacers...?

Re: 69 CB450 from North GA

The problem lies in where the engine is mounted, so you have to line up your rear sprocket to the front, like you said with spacers. Whether you're using the swingarm or not. I think you'll find that the 750 rear wheel won't work but I could be wrong. The 750's rear hub is wider than a 450 so it'll push the sprocket out more. It won't line up. If you line it up then the wheel would be off center in the frame. I'm not saying it's impossible but it'll be a pain to get right. You'll likely have to get the 750 hub machined down, or use the 450 wheel.

Steve can back me up on these thoughts I believe. He's the one that helped me out and knows his sh*t...

Also, Henryiva might have some suggestions, as he built one hell of a hardtail 450, and it's on here.. A yellow bike.. Very cool. :cool:

Re: 69 CB450 from North GA

I appreciate the help.

If I can't get it to work, I'll just run the ol pizza cutter anyway n keep it super skinny. I may look like a circus bear on it though. Ha.

You can always relace the hub to the 750 rim, you just need to make sure the wider tire does not interfere with the chain. It would be a job, but it could be done.

You "might" be able to go up 2 tires sizes but if I remember right that'll be your limit...

Re: 69 CB450 from North GA

The only thing with the 750 wheel is that it's a mag. So I think I might have a hard time lacin the 450 hub to the rim. Ha. ;)

Re: 69 CB450 from North GA

You CAN lace a 16" "Harley rim" to the 450 hub... This maintains your sprocket spacing (alignment) and the chain and swingarm will JUST clear a 120/90 (5.00 x 16) tire... If your hardtail is a smidge wider, you MIGHT clear a 130/ but it will be right at the point of rubbing the chain/tire (with any chain flex at all)............ Spoke/rim "kits" to do this are on ebay from time to time.....
