Modern forks on a CB450

[Dragsterhund]

I'm looking at a couple different options for the front end of my CB450, and I'd really like a set of upside down forks with some modern disk brakes. Assuming I can find something that works, would I be stressing the frame too much, especially around the headstock?

Honestly, most modern front ends are lighter than what came originally, and no matter how much brake you have, the bike won't get heavier, so the stress should actually go down....

I hadn't thought about the lightness aspect, I was thinking more of increased braking power putting more stress on the headstock.

How bad of an idea would it be to use a set of forks from a YZ125 or something like that? Single disk, spoked wheel, I'd have to change the springs and shorten the tubes, but I can have them machined...

The YZ cartridges are probably too big to shorten enough.

YZ forks are strong enough though.
