Pull your side panels. Is it similar to the road grime/brake dust? My XCT is grimy, if that is a word. Lots of dusty stuff that isn't really explainable, but all seems well 20 odd K miles and the belt, brakes and such seem to be wearing normally. I just figured the belt drive and openness of the machine was to blame. Lots of street cred on our jackets accumulated quickly compared to the past shaft drive bikes.
