Wow, Larry! That looks great. If I was interested in pulling a trailer, that is the hitch and trailer I'd pull.
Thanks, Larry. That looks great. I'm in for one if you're taking names.
Larry,
Did you change the preload when you had the trailer connected?
Larry,
I figured I'd answer here as PM is not as fast.
I had a unigo on my ST1300.
It would wobble with aftermarket Delkevic pipes installed. The pipes are 2-pcs and have a band whereas the oem pipes are all one piece and use a welded tab to connect to the exhaust hangers on both sides of the bike.
The hitch you show, has 2 vertical support bars. I'm thinking they are not stiff enough to handle the tendency the trailer has to wobble.
When I had the hitch on the ST and the aftermarket pipes, I could stand on the hitch and push and wiggle it as much as I wanted to and it didn't budge, it felt as solid as it needed to be. But, at speed it would start wobbling, didn't matter if it was empty or full or what the tongue height was doing, I was afraid to ride it 10 miles. But, once I put the oem exhausts back I rode it to California without a single issue.
Hey, Joe, have you used a 2 wheeled trailer, and if so, does IT also cause a wobble?
No sir, I have have, but may ST-Owners have and don't report any issues. I pretty much gave up on the trailer idea after the unigo because I ended up just packing more and more stuff and kinda like to keep things a bit less complicated.. LOL
For me anyway..
Yes, the difference sound like it's in the hitch. The one welded to the scooter frame sounds beefier and much more solid.
The issue with the unigo is that you aren't just pulling a trailer, you're supporting it. The tongue weight on a unigo is many times 2 or 3 times that of a 2-wheel trailer... so, that will magnify any trailer issues as well as transmit them to the bike itself.
On a 2-wheel trailer you are supporting the tongue but you balance out the load over the trailer wheels so it's at a minimum... you actually just pull that trailer and support it just enough.
Compare a wheel barrel w/heavy load to a push cart w/same load... any imbalance or weak point while using a wheel barrel is apparent immediately but you can do just about anything with a push cart.
http://www.thirdwheeltrailers.com/index.php/home has a very interesting design which creates a good solid point of mounting... I don't have any experience with them though or know how easily something like that could be fabricated to get your unigo to pull better.
