Sorry, forgot about this thread.
After weighing the rear axle loaded, my EXP was going to have the rear tires very close to max load, axle wasn't even close with an extra 2500# available. So, I had to keep it light as possible.
My solution was to modify an existing MC rack laying around here and use the existing 2" receiver hitch on the bumper. I added additional stabilizer bars that tie into the bumper and keep it from rocking side-to-side. The 2" bar then only has a vertical load. The rack ended up being about 40" high, so pushing the bike up was impossible.
I built a lifting crane that used an existing heavy bracket attached to the rear bumper. I had some 2.03" ID honed tubing for the base and heavy 2" tube would slip in with just enough room for grease. I used a 2000# warn ATV winch for lifting power and tapped into the rear 16k truck winch for power. This winch was very fast, so I removed all the cable to leave the first wrap only. It is still very fast, maybe takes 5 seconds to do the lift.
All the hardware maybe adds 150# to the rear. With my 330# KTM 690 on back the rear tires are about 200# over max weight. I keep them pumped to the max psi, don't drive over 60mph and watch the tire temperatures close. The crane just lifts out of the honed tube to reduce weight.
It's easy to load, maybe better than rolling up a ramp. I made some straps that loop through the frame at the balance point. These are a little fiddly to install, but goes quick when I remember the right technique. Then 5 seconds to lift, swing it over to the rack, install the tie down tubes and tie down. Takes about the same amount of time as any normal motorcycle loading.
Downside is if I have a flat on the truck. The motorcycle will have to be unloaded to retrieve the spare tire. I'd probably plug a tire first.
