Is it safe to load a big touring motorcycle into a TH??

I've hauled my Goldwing in my TH. Tieing down is a bit of a challenge but if you do a search you'll see lots of good ideas, most include a chock. My TH has a "beaver tail" that reduces the ramp slope. If you're dresser is lowered it might be a problem but it really is not hard to load/unload; just use the front brake and clutch for braking. In my case the wing has reverse so its even easier to unload than your HD.
