It should be able to haul two bikes. We have had my dads Roadstar on there which is about 800lbs and it was fine but have not tried two. If you are interested I could put an R1 and FZR on there to see how it wil work but I think it will be fine.
Tim, does the trailer have a license plate? Maybe I could come out a take a look at it this weekend. Why don't you email me with your phone # if you're going to be around this weekend. [email protected]
