I am looking at purchasing a 2005 SSR 110cc Pit Bike for my 13 yo son. He has a small mini bike and we are looking to upgrade. The bike we are looking at in on craigslist for $475 and has the following description. For sale is a 2005 110cc SSR Pit Bike. The bike comes with an aftermarket rear spring/shock absorber ($200), an extra carburetor, a new set of street tires on rims and a set of nearly new offroad tires on rims We don't want the street tires so he is taking the price down to $400. Any thoughts are appreciated as we would like to go look at it soon and I really don't know anything about pit bikes at all. Thanks.
