Why do most grey 250s in shops have current-looking colour schemes?
After spending a decade in the open air in a Japanese holding yard, a bike will look pretty secondhand. Even if the bike wasn’t already carrying damage when it first arrived at the holding yard, chances are it will have picked some up while there or, more likely, while in transit from Japan to Australia. For the bike to fetch a good price, it should look pretty (see earlier comment about n00bs being easily impressee), so grey importers respray and resticker the bikes as a matter of course. Depending on who they farm the work out to, the result can range from average to quite fetching. The condition of a grey 250’s fairing is no reflection on the rest of it.
