In a haste, I bought a motorcycle ramp for the trailer. It works fine, however it is a bit skinny for the wide tire on my 'busa. It was more meant for a dirtbike. It could work for sportbikes and i used it this weekend, however I don't feel like flipping it over to have it work.
Paid $58 inc tax at RIDE
$35
