Tony, They are the wheels shown on my avatar, not reverse Comstars. They are off a cx500. I ran them thousands of miles since I put them on the bike. You can pick up some RPMs because the tire that fits the 18 inch rear is larger diameter.
I have them in SW FL, 33907, crated with useable Michelin tires (was running them till last year when I switched to Turbo wheels). I have them crated with a rear end pumpkin to match. The crate is 220 pounds.
The front wheel has been modified for twin discs.
BTW, the bike won AMCA first prize with these wheels two years ago at Barber.
The rear will bolt right on. The front will need new dual brake forks which I have available.
I never liked my single disc GL500 front end. Not enough stopping power IMHO. So I changed to this setup I'm offering. After running it for 5 years or so I changed to Turbo wheels (with rear disc) and a front end from a 83 GL650.
Wheels, tires, brake discs and rear end $200 plus shipping.
GL 500I forks in perfect condition (new seals, no leaks, some small pitting which have been filled) (without calipers) and will bolt right on (may, may not need head bearings) are $100 plus shipping.
