45,000 maintained miles I wouldn't bat an eye at buying as long as you're prepared to replace a few things if needed, none of which are terribly expensive (unless all of them need it).
Likely culprits are:
Detent spring
Headstock bearing
Wheel bearings
Valve adjustment
Water pump and hoses
Tires
Brake pads/fluid
Grips
Coolant/cap/t-stat
Battery
Air filter
TPS
O2 sensor
It's likely most of these are perfectly serviceable but they're the things id put on the inspect list prior to purchase.
