Learn AT the MSF and you won't have to learn on your bike. The MSF courses around here always have super-low (e.g. old Honda Rebel) bikes available.

If you've already taken the course, you've got this skill already. If you haven't.... well, it's useful even if you're already a rider. I had a hiatus of several years in my riding career and took it again before getting back into things to knock the rust off. Worthwhile even though I knew how to ride.

Alternate thought: My preferred method of loading my track bike on its trailer is to power-walk it up the ramp, while standing next to the bike. Exact same principle... you need to feather the clutch while applying just enough power to avoid a stall.
