That guy just sold that bike for around $5 large to get an XR600 to race. You can find clean TAs for $4,000 and not so clean ones for $3,000 look on CycleTrader right now there's 3 of them.
Personally I'd love that AfricaAlp, but a stock one with 40,000miles on it for $4,000 seems a bit much.
From what I've read the Transalp is more of a street bike, where the Africa Twin is more suited for the Dirt (more suspension, greater fuel capacity). The Varedero seems very street oriented. If Honda were to build a Real Adventure bike, and price it just under what a KTM or BMW would cost they'd sell a lot of them. 1989 was A LONG time ago, and there's a lot of BOOMERS out there right now getting ready to retire with dreams of cross country tours, Honda could have a hit, instead they'll just loose out once again.Check out this guys petiton to Honda!
