Hack Trailer towing?

I've run across a very reasonably priced MC trailer which I am considering pulling behind my sidecar rig.
I've done no research in this type of application so thought I'd throw it out here for opinions and experiences.
I think I'd "can" the cooler....but on 2nd. thought....



Common sense would tell me to center it between the Tug wheel & Sidecar Wheel?
But.....I've seen photos of other rigs mounting them directly behind the bike?

Any comments / opinions / experiences would be appreciated.

Two things to consider.


1. Overall width if the hitch is towards the bike.

2. If the trailer is heavy it will pull the outfit towards the chair if the hitch is more centered ... but it still depends on track to a certain degree.


On the harley I centered the hitch ( 48" track ). This build, it is towards the bike.

Apples and oranges ... pick one.

I'm pulling a much larger trailer (Bunkhouse) than what you are looking at, though I do have a K-Tractor as opposed to your airhead. My hitch puts the left trailer wheel in line with the bike track. Right wheel is just inside the hack wheel track. Hitch on the hack frame somewhat limits the tendency for the wheel to lift.









I don't find any 'excessive' push & pull loading over what the hack already exhibits, but it is there, and I do have a brake on the hack wheel.
We limit what is in the cooler when on the road to some drinks & just enough ice to keep things cool. Other groceries in the trailer to keep the load balanced.
Important to remember with the trailer is just because you have the space, it doesn't mean you have to fill it!
And just as when I was pulling with the solo bike, putting the luggage weight in the trailer allows the bike suspension to work better.

Absolutely agree

After a consensus, looking at my set up, we came to the conclusion that the mounting point would live inboard of the tug tire, about where yours lives.
I'm thinking the outside left side of the trailer will need to be slightly inside the bikes furthest point.
Sadly....the trailer comes from a state where no Title / license was required. My state requires Title / License.
That puts a "hitch" in the deal. Title Applications are a PITA in my state.

Whatcha gonna tow the trailer with? Most outfits will get it rolling but stopping safely can get exciting. With a Ural outfit I'd keep the gross weight(trailer and cargo total) at <500 ibs. Regardless of brand bike and it's new enough to have a warranty towing a trailer will likely void the warranty. Good luck, be safe.

Warranty?
Ya right....last new bike I bought was in 1971...

If I go through with the trailer set up, it will be behind my BMW Airhead rig. 1000cc tug, dual front discs but no sidecar brake.
It stops quite well as it sits...adding that much weight might make it a different animal though.
The goal is to relieve some of the weight off the tug as we camp quite a bit.The bike is fairly over loaded when all geared up.
Dragging an extra few hundred pounds of trailer might not be the answer, but I'm game to give it a shot.
I might also pull the trailer behind my naked goldwing.
I'll be taking a look at the trailer on Thursday. The seller and I haven't been able to coordinate our schedules yet.

Finally hooked up with the seller of the trailer after a week of "phone tag".
He had just pulled the trailer to a "for sale by owner" lot near my home...also had dropped the price an additional $50.00. Now asking a whopping $300.00. Holy smokes, at that price I had to buy it. It would have sold quickly at that price on the lot.
He towed it over to my place so I could take a look at it up next to my sidecar rig.


It needs some clean up but has recent tires, including the spare. Wheel bearings were redone as a matter of maintenance recently too.



The top rack appears backwards to me....will reverse it.
The trailer is small, body is 36" x 30". It actually would fit directly behind my sidecar rig without extending out past the bikes footprint. I'll likely mount it behind the bike as I think the geometry will be better.(?)



The interior has been upholstered and over all the thing is in good shape. The spare tire / cooler add some to the tongue weight. Might want to move the spare tire to another location. The axle sits a little rearward so tongue weight is around 20 lbs. as it sits.
I also have an old "naked" Goldwing so the trailer might be a candidate to pull with it.
I've never used a MC trailer before, so there will be a learning curve.
Not sure how long the "Harley" mudflaps will stay....guess I could reverse them.

I bought a trailer last year, for a similar reason, a friend was selling it for such a low price, I thought if I don't like it I could resell it easy enough.

My towbar was on the sidecar when I bought it and is in a similar position to Bobmws except on the other side (left hand sidecar). It tows and stops without problem, even though I don't currently have a sidecar brake.

Mine had a spare, mounted like yours. I removed it to fit a stand, as it didn't have one and weighed it. It weighed in at 7kg (15.5lb), so I figured I don't need to carry that much weight when it only fits two of my five wheels, so bought a compressor and puncture repair kit so I can fix any of my tyres not just the trailer and it weighed less.

Thanks for the input Jeff.
You are right about the "spare" tire. Will likely abandon it at home and be prepared for repairs as I am with the bike tires. I only haul spare bike tires when on real long trips when I anticipate tire replacements on the road.

I'm seeing a real simple way to install a hitch on my set up.
I can run a solid heavy 3/8" (or maybe thicker) steel strap down the length of the sidecar frame, exiting inside the rear wheel by about a foot.
I can u-clamp the strap to the frame without any welding. ...we'll see....

That's a nice size trailer.

I tow this for longer trips/rallies and it is set up so the right side trailer wheel is in the wheel track of the bike.

Works a treat.

BMWhacker,
Looking at your trailer I think the rack is placed that way so when you open the lid the cargo on the rack stays in place.
When pulling with your solo Goldwing, ride as normal except, allow more room for braking, brake well before any curves. Braking in a curve will have the trailer wanting to go straight and push the rear wheel to the outside of the curve. You will learn maximum lean angles! Once safely in the curve you can accelerate as you wish. Also remember to account fo rthe extra width!
