I know this bike personally, it's in amazing shape, and the miles are legitimate.
The bike came from California from a guy who bought it back on 2001, got deployed to the sandbox, then came back and rarely rode it. Got married, had kids, cranked it up and let it run periodically, then sold it to his cousin in Utah.
Then he put new rubber on it, changed the tires, all fluids, etc.
The current owner replaced the tank gasket, and rode it a bit, wife is forcing him to sell his toys (he has a few motorcycles)
If need be, I can act as proxy, and can assist in helping it get packed up to ship. I have a friend that works at a motorcycle dealer that frequently throws away crates for Triumph, and I can get the packaging to ship it for free.
