Always remember you will have a much better handling trailer if you go with a trailer with torsion suspension versus leafsprings. Leafspring trailers are bouncy where as torsion axle traielrs are not. The wheels dont matter as much as the suspension as far as handling.

I had a couple of people meassage me asking if I ever got an answer.  Yes I did from my good friend Richard (HarleyMan).  He moved his axle around until he found the the tongue weight that provided the best handling of the motorcycle.  He suggested a tongue weight of around 45lbs.

Look at Bill's Trailer Sales. www.billstrailersales.com. We attend many shows during the year and service everything we sell on the road. We install hitches and wire bikes too! .

I just got home (California) after a 4095 cross country bike ride. Pulled a trailer just like the Harbor Freight one. Other than eating up you gas mileage (and rear tire), thats the only way to travel on long trips. Was able to carry all of my camping gear(as well as my brothers), clothes ect. Once you get used to it you dont even know it's there. Like I said, it will eat up a motorcycle tire. I switched to the darkside (car tire) when I got home and am looking forward to seeing lots more mileage with it!!

I've been pulling a cargo trailer (21 cu ft) for for 5 years now behind a Ultra. Whenever I take off on a trip I weigh it on 2 batrhroom scales at the wheels and a 50 lb fish scale on tounge. I never go over 25 lbs tounge load. More than that eats the tire 4 times as fast as without trailer (my experience). Get a swivel hitch too. My father cut an entrance tight going for gas and hit the curb with the trailer tire and it slapped his Wing down. Sprung the trailer tounge. I run a torsional axle and 14" low profile car tires for a smooth floating trailer. Mine is one of the coolest trailers I have seen, but made my ass hurt when I paid for it. ( www.american-legend.com ) Will post a pic on profile in a bit. When my wife & I travel I would not be without it. Did without for over 20 years packin bikes. Now I can take the kitchen sink if I want.

My brother is building my trailer for me, we found the harbor freight trailer frame, and we're using a light weight aluminum box. I found my hitch at www.mchitch.com

We did over 12,000ks last year with trailer on . Best way to cruise.

Several guys I ride with pull a trailer on long trips. Most have the American Legend trailer and won't have anything else.

I was going through some books for engineering and trailer build guidelines. Straight trailer design axel placement for 60% front/40% rear load balance gives good tounge weight and good tow balance. Load front heavy to prevent fishtail.

I been towing a trailer for years, hardly noticeable when traveling at speed, and only noticeable in starts and stops. In a way it appears to give better balance to your bike when traveling. Make sure when loading, that you evenly distribute the weight in the trailer, heaviest stuff over the axle..

You gonna have that trailor ready for Redwood????

in Australia it is recomended to have 5- 10% ball weight
we manufacture trailers and rule of thumb is to have the axle1/2" back from centre for every 12 " of body length
But all comes back to how load

I hope so.  If not I'lll ship my stuff to you to put in your trailer!

How much difference does the wheel size make to the ride of the trailer?

I see some, like the Harbor Freight trailer with little 8" wheels, and then many people with 9" or 12" wheels.

also check rating on towbar/hitch
in Australia they have to have a rating on it giving max ball weight and max trailer weight

i have 10" wheels on ours
tyre pressure is very important
it tows great and is no prob
the bigger the wheels the less stable as gets higher off ground

with the small wheels check rating of tyres

Changes the way you ride, and the way everyone rides who is with you. Though convenient, curves must be taken slower, mountain curves are annoying, even on the straightaway riding is slower. The worst trip I ever had was with another person who had a trailer, and it was very small. Spent two weeks poking along the roads, riding through curves and driving as if we were in a car. Straight up and no lean. Yecch. If you get a trailer, know you change your ride.

if sitting on speed limit it makes no difference even thru corners
altho im not a boy racer
loaded right it is only braking it affects

lOAD RATING IS IMPORTANT BUT MOST OF ALL IS SPEED RATE OF BEARINGS. Some small tire wheel assemblies are not made for highway speeds such as wheelbarows utility carts. The smaller the tire the faster the rotation and the more bearing, lubrication and the balance or tire construction for highway speeds add up. A weight saving idea is rubber torsion axel assemblies that would replace the axel tube, springs and spring mounts. They are bolt on and cost is about the same to slightly cheaper than spring assemblies but a lot easier to assemble.
