Dual Sport Trailer assembly thread

Primered and painted. Think I'm done with it. Maybe a nice polished wheel and some new shocks.



Cut the brake drum off the wheel and made a spacer.

From conception to completion seemed to go fast. Nice work, looks factory.

We're ready for the moto cross video.

oPAULo, that's friggin' awesome!

DakarNick, very impressive, well thought-out engineerin'!

Scooter shop! Got mine for $10 bucks.

Edit: Tire and wheel for $10 bucks, not the shock...

Good friend was drooling all over mine so we made another.
2 of us built it in 7 hours including lunch, football and Nascar breaks.
No, I am not selling these.

Nice, Paul! I have seven hours in mine just running to Ace Hardware, ordering from McMaster-Carr, and making the bracket

Starting my trailer build. I am starting at the bike and working my way back. It's going to be a single wheel job. I can get all my camping gear for a weekend into belly bag, saddle bags and back rack but I can't do all that *and* carry my glider. I built a cargo box that bolts to the back rack but with all my gear and the wing stacked to the moon the bike is too light on the front end and doesn't handle well, particularly on mountain roads (which is where I need to go fly anyway). Thanks to everyone posting in this thread for inspiration.


I had some stainless bar stock around from a project I never completed so I'm using that for my hitch attachments.


Spot welded the indexing plate. Some day I'll make myself a CNC machine. For now I have to fab stuff.


I'm not sure this gusset is necessary but it was easy to add so...



Right side temporary installed on the bike. I wont drill it for the attachment until I've made the trailer forks up. Back to the scrap pile to see what's available.

Here is a link to my trailer build for a KTM 950se. If I did it again I would lighten it up but overall it works great!!

That's a nice trailer Pitster,

I wish I had a motorcycle bone yard to pick from but I have to deal with what I have on hand. I'm also building a trailer for a little different purpose than most do. Mine has to fit my glider and all my flying gear as well as keep it out of the weather.

Here's my progress so far today.



I had a couple of lifeline stanchions that make good forks. I have 3/8 bolts to hold them during construction but will go with straight pins and ringdings for the completed trailer. Maybe pip pins later if I can find some.



A mountain bike head set. Unfortunately the frame part of this is aluminum but I have a plan to deal with that.



Here's the "hitch" part of this deal.



Yes, that's a binnacle instrument pod mount from a boat... your point? heh heh

Once I get the tire and shock arrangement worked out I'll put a bolt right down through that aluminum part to lock that cross frame in place.

OK, back out to work some more.

I love seeing this explosion of trailers!! I do hope pulling a trailer with a dual sport becomes less "odd"

Great to see all the different builds. We all have different goals in what we'd like to carry. Just as long as we get to get out there and enjoy ourselves that's what it's all about!!

Took my trailer out for some fun this last weekend:

I have new pics but webshots is going defunct and going to a new site do uploading is a no-go for now. I'll get some more done, take a few more pics, and maybe someone can host them for me?

Post them over in photobucket for now photobucket.com
..and there is always smugmug.com we have "in" there

Swing arm and stub axle with "shock" (really just a coil spring).



Wheel and tire. I'll tow it around the block a few times before I install the box and see how it does tomorrow.

So how did it do? To me it looks like it might not be stout enough where it connects to the backbone/frame. But I'm just looking at a photo :>

Gregory Bender

I signed up for Photobucket. I'll post more pics tonight

Here's a couple...

Sorry, guys. I moved them to a different album and forgot to re-link. Here they are:





I live in an apartment and have a one-car garage. The dogs hate being away from me, so I block them in with the tubs and table, haha. Then they can be out there while I work. But I have to toss them back inside when I weld.

That's Beau helping me. Ruff is behind the rear wheel and to the right.

So, anyway, here it is so far. It's all 1.00" and 0.50" square tube except for a bit of flat to make the bike axle mount. The 1.00" tube running lengthwise in the first pic will be the main spar. In the second pic is the 0.50" frame that will sit above the spar a bit and I'll run angled braces back to the spar.

Bike axle is 7/16"
Front pivot is 3/8"
Trailer axle will be 3/8" or 7/16", depending on what I use to fit the wheel hub.
All pivots are bushed with graphite-impregnated bronze bushings
All axles are simple all-thread with a nut welded on one end

My shock should be here by Friday. That's the next thing to do besides add some bracing to the bike-side pivot.

I realized I left out one pivot. Rear swingarm pivot is 7/16" also.

I may need another 20' stick of 0.50" tube. $17, not bad.

Looking pretty cool Nick!!
