A friend at work has a 1993 KTM 300 EXC that he bought when it was a year old. He hasnĀ“t used it since, save for starting it up every year and riding it around the yard. He wants $1100 for it. It needs a side case as it has some holes in it. Other than that it is in great shape. Is this an ok price for this. I want to get it for me and the 15 y\o son. :) Any problems with these bikes?
