I have been using air for over thirty years to dry the cars and bikes. If you have filtered air (acceptable for painting a car) I just use that with a rubber nippled blow nozzle, adjust it at the regulator to whatever pressure you are comfortable with and dry away.
Have to be careful using leaf blowers as some of the better, read newer, have the exhaust going thru the blow hose. If two cycle you will get mini oil spots from the exhaust residue which is not good.
A Metro or similar Dog or Motorcycle type works very good, I have mine bolted to the wall on a easy remove bracket that came with it and a 20" hose, that also came with it. Works exceptional but regardless of what has been said, you cannot blow the bike completely dry without leaving spots, still need some type of automotive drying towel in conjunction with the blower unless you have treated water (soft).
I find it humorous that adults will make comments like "ride it @ 70 MPH, it will dry". Yes it will dry, and it will look like someone washed it that had no idea what he was doing. People like that, make mine look better than it actually does, I like people to think it is new, regardless of how old it is, car/bike/boat or whatever.
