Guys, you are ALL missing the boat here................TWO RAMPS! REPEAT.............TWO RAMPS! (Alloy ones, at least 8 feet)
One for the bike, pne to walk on. Use tie-downs on BOTH ramps to attach to your tailgate or bumper, then start the bike and walk it up on the clutch. EASY EASY EASY/
TWO RAMPS! Trust me, I've been loading streetbikes SOLO into trucks for years! I have even loaded a BMW K1200LT into a trcuk singlehanded in SNOW!
TWO RAMPS, Tie them to your truck so that if you give it too much gas by mistake, it doesnt spit the ramp out, then walk it up on the clutch.
