Got curious and started looking at ways to shave a little mass off my 93 1kf. Most people recommend lighter wheels, but as with most things on a bike this old, I'm having no luck. I've got a set of Pilot Road 4 GT's ready to mount, and figured this is as good a time as any to look, lol. Thanks

 

Anything can be made to fit but I doubt you'll find anything that will be a direct replacement without spending mega bucks on the likes of Marvics/BST/Dymag etc and then you have the age of the bike to contend with as it's no longer current.
Maybe your best bet would be to find a lightweight wheel like the current Blade / ZX10's etc and get spacers made to suit, then you'll need to ensure the brake discs will still accommodate the callipers etc.
This may turn into a bit of a project.
