i haul mine in a short-bed Nissan with no tail gate and we had to sort of caddy corner it. rode 300 mile staring at it wondering if it would fall out. it didn't. not fun though.
my advice: if its too long get it strapped in with the tail gate down yank the rear tire over to one side of the bed put the tailgate up and pull the rear tire as close to center as you can. the adjust your strap until its fairly straight. i do this every time i haul my bike.
service manual say its 82 inches long over all
