MATCHLESS G80S 500CC ProjecteBay
Matchless G80 in need of restoration
Please study pictures, most of the parts are there, all the important bits are present. All bodywork panels. There are two bottom ends one from model 16 and other better one from g3. Big top end in decent condition. New seat. Everything as pictured.
There is no documents.
Bought this as retirement project, but now I need the space. This will be great bike when done, cheap way to own 500cc single. Collection from Doncaster, cash on collection or bank transfer. I can deliver for fuel cost but please ask first.
