Because my M/C budget isn't unlimited, I've ordered a Piggybacker trailer to pull behind my R 1100 RT.
Found a Uni-go hitch in Colorado and flew home with it on Tuesday. Disassembled it and put it in a duffel bag as checked luggage.
Lots of different choices of trailers and which one is the best. Whole internet community of folks who buy Harbor Freight trailers and convert them.
The reasons I bought the Pig are:
1. I've emailed them several questions and gotten prompt, informative responses.
2. Independent suspension
3. 12" tires
4. LED lights
5. Swivel hitch
6. Very good reviews from users on other fourms.
7. Free shipping right now.
8. Uses standard size bearings which you can get at any NAPA
It's not a Unigo or Bushtec, or whatever you have and think is the only one, and it wouldn't be the trailer for some others, but for me it will be just fine.
Should be here next Friday.
