I will admit I actually clean my busa at the car wash. I'm careful not to direct a full strength stream at it and I don't shoot into the fairing holes. But it works great and quick. I know this is supposed to do this but been cleaning my bikes that way for many years. When I saw the iron rust on my house from the hose I quit using that water.Yep sure is, all bodywork is original from 2008 minus the tank of course. Fairings get a yearly cut and polish on top of cleaning after every ride.
But back to the point, your bike looks amazing!
