A buddy just bought the exact same model, similar mileage, almost as clean , I mean really close to that clean it amazing with Jesse bags and lots of farkles for $5000
I also had the exact same bike and I wouldn't worry about the bike itself, mine had 100K miles and ran like a top. I sold it for $6k with farkles.
I think the price is too high.
