This summer I plan on getting a street bike (gsxr 600) and I want to buy a used one because I dont want to buy a new one and lay it down which will probably happen. I was just wondering, if i bought a used one from either a dealer or ebay, how many miles are too much. Basically i dont want to buy one with a bunch of miles or something and start having to replace parts the 1st week i get it. so basically, how many miles is too many on a bike. THANKS
