OEM bits for a CB 550, K model including side covers switch gear and original clocks, ignition barrel with keys, sissy-bar, finned tappet covers and some other bits for sale.
Fenders, regretfully the front is sold:
Side-covers and clocks, and he has the ignition barrel and keys.
Headlight...
I'm not 100% sure on the front tyre profile (I can find a 90, not an 80) but the Bridgestone Spitfires are goodlooking tyres which a friend has on his '79 SR500 and I currently have them on my '73 Honda CB500.
