I have been thinking about a 450 for a while now. Today I heard about a 2005 YZ450F that belongs to a friend of a friend. It's in mint condition and has only 4 hours on it. My friend also said it has a ton of extras, not sure what all those are though. What would something like this be worth? He is asking more than I would expect for a 4, almost 5 year old race bike. I have a 2005 YZ250F, and I'm particularly interested in this one has I'm thinking a lot of my stuff (hand guards, seat, skid plate, and a few other odds and ends) would swap right over.
