Building a single wheel trailer

I've been thinking about making my own for years and finally got a start on it this winter. I plan on having it haul a set of saddle bags and top box. I really have no good reason for it as I don't do any long trips (yet) but maybe that'll be in the future.

Started with a spare SV wheel I've had. Sourced the swingarm and lightly twisted DL1000 subframe from Ebay

Seeing how bags might fit

Waterjet cut swingarm pivot brackets

Test fitting with a shock and center stand from an old Suzuki FA 50 moped

Added some cross bracing to stiffen things up

Moped shock wasn't going to be stiff enough so I fitted one from an 81 GS750

So far, that's what I've got done. I'm able to get good frame tubing and try different shocks because my father has a lot of parts bikes left over from when he owned a dealership up to the early 80s. I've got a top box on the way and have sourced one factory bag so far. Once I find another bag and racks, I'll be able to do a lot more work. Next big step is attaching it to the bike. I'm pretty sure I'm going to use the bike's axle and my main point.

I am so impressed with your start.

If you haven't already check this thread out. Ultra Light Wieght Trailer Project - Data and Experience Welcome

Here was SKS idea. Yours is looking pretty darn good.



I am saving this thread as a favorite and will follow your progress. Very impressive!

Also, check out surge brakes. I think you could easily make one for the trailer so the disc brake becomes functional.

That is a unique placement of the weight, suspension, and pivot point. I haven't wrapped my head around it yet, but at first glance it looks like it might work. Have you done the math or created a test jig to check the weight vs spring and pivot?

Very cool! Just a question, but would the GS shock not be too heavy duty for your needs, as I would imagine that a 'softer' shock would not allow the back to 'hop' and so cause a tugging effect on the towing vehicle?
I also thought a smaller wheel or at least one that was narrower (perhaps a front one) would be better for drag, again, just throwing questions out at you. I'm very keen to see the finished product.

Try google search for moto mule trailer. More off road related, though.

The GS shock isn't going to work. It has a too light spring or maybe blown; either way, when I tried the racks and bags from my bike, it squatted way too much. I'll just have to keep digging through my father's stash. I tried one from my SV but it's much too stiff. I think I'll be moving everything forward 4-6" regardless of what I find to bring the weight to the front, it's back heavy now.

Found different sets of damaged bags and made two good ones out of them... still looking for racks though I'm going to try a shock from a 2000 GSXR 600, I think it'll be the right rate.

I've been working on a design for a trailer also. Stop and think about the weight that you will be hauling. Say about 50 or 60 lb. max. so what I was looking for was a small dirt bike mono shock.
I do like what you have so far.

The rear view is inspiring. Add a luggage rack and some form of trunk to encompass the mechanicals like SKS design and you have something truly unique.
