Been able to load Dual Sport bikes with the 33" long mesh ramp on my 4X8 trailer without issues, trailer deck is 12" high where ramp rests. The engine will contact the trailer using the 33" long mesh ramp with some bikes, probably would with my FJ09.
Removed the mesh ramp and started using a 6' long aluminum ladder type motorcycle ramp purchased at Harbor Freight and have not had any problems with any bikes loaded so far, use it with my FJ09, too.
Also mounted a removable front wheel chock. When buying a chock, make sure it's low enough to clear the front wheel rotors.
Used this trailer with side boards today to transport a 1/2 yard of gravel. It gets plenty of use, not just for motorcycles.
Hope this helps,
Bill
