Sounds like you'd also believe the RRP is $4499 lol. It is a YX engine if you look closely you can see it stamped on there and you can see the head is the KLX style. That bike has a good motor but crap everything else. Mitz is onto it when he says the rest of the bike can't be worth much. A motor isn't always the most important part of a bike.
