I've got a long ramp and straps it's a 4 meter ramp so easy to push plus I'd lend you some ratchets straps.
I've also got a short ramp (Would fit in a car for collection) which is a very agressive angle and you have to power/ walk the bike up while feathering the clutch....
these ramps are £450 to buy we use'em all the time for our road trunks rated to 500Kg....
