Hows it going people,im seeking some advice on a wee bike ive been offered,it will be my first trials bike,its a 1997 scorpa 250,the guy selling it seems certain its powered with a yamaha engine,ive only seen pictures of the bike and will go for a better look this weekend,am i right in saying it should have a 250 rotax engine,if so how hard is it to get parts and are they expensive,the bike is reasonably cheap but dont want to buy somthing i cant get parts for,also are there any issues i should know about with this model,any advice is much appreciated
