I'd go with Mr. XT on this one.
Foam and low pressure hose. Sure, just don't spray the engine or air cleaner, & go easy on the wheels.
I have used a wheel cleaner at those on a few bikes. Basically the same as at home with the canned stuff and a hose..
Those run very low pressure since you don't want to force water & cleaner into bearings and the like.
High pressure. No.
