I'm currently running a contest for new designs for a pull behind motorcycle trailer that is coming out soon. There are currently a few up for Harley D and Yamaha. 

Check it out here and submit one or forward this to a designer that would want to enter.

Maybe we will have a vote here towards the end of the contest. ....

whatya think?

Looking sweet.Not one to pull a trailer myself,tho these look like they could handle the road well & in style !!!

They look great, but why Two wheels instead of one behind with a shock tower?

Nice graphics but I would be concerned with the tongue and overall weight of the unit with that big of a box and tire.

Yeah it does look like there is a lot of the space in front of the wheels which would make it hard to adjust the tounge weight down.

But I really like the looks!

I like the graphics also.

I do not like the design.  Most non-Aerodynamics design I have ever seen would be like a wind stop behind you.  I would think more wing shaped so the air flows around it.

Then tounge, like others have said, looks problimatic.

But good luck with your competition.
