They're only original once and this very low mileage (1270 miles), unrestored, 1990 Honda GB500 TT looks like an excellent example of this very desirable model. The only non original part is the Supertrapp exhaust, a very common swap which, if replaced would return this bike to a completely original state.
All metal surfaces also seem in excellent condition, the pitting often seen on the front forks is not present and chrome and other surfaces seem to be in great shape. Painted surfaces all look brand new. The tool kit is present and intact.
The seller says the bike was just tuned up, a new battery was installed and all fluids were replaced. So there's nothing to do besides ride it. It's for sale on eBay.
