I bought a mint condition 83 xlr500 r off a good mate of mine for what i thought was a pretty good price. Hes had it since 83. It broke his heart getting rid of it but he needed the money. So put a new battery in it, some fuel and she fired straight up after sitting there for 8 yrs not started once. He said its literally only got like 30-40 kms on it.. so could anyone please give me an indication of what one of these would go for 😊?
