Just finished mine, for a WR250R Yamaha dual sport bike.
The hitch is 28" high and no place to put your feet, so riding it up is not a good idea, and she is too heavy to push.
I used a small winch and a "snatch" block. Put the cable on the right foot peg, and with my wireless remote, just hit the button and she is pulled right up at just under a walking pace.
I had to use a 14" hitch extension so the handlebars are not too close to the coach, and I reinforced the hitch mount on the coach to better take the weight.
Pict 1 is the OEM hitch mount = not so good.
Pict 2 is my fix with 2 x 2 x 1/4" angle and grd 8
bolts
Pict 3 is the bike rail
