I think it has a lot to do with it. With the passengers head so close to the pavement and or scraping the pavement in the turns is does make sense....

I've discovered passengers have excellent reaction times

Passengers

Passengers don't have to be part of the ride on a modern bike- in the early 1920s when a Triumph weighed 210 pounds and the sidecar weighed 95, they participated in the ride by anticipating curves etc. The passenger and driver weighed almost as much as the outfit.
But now their weight would be a much smaller fraction of a modern outfit's overall weight, and they just sit immobile like car passengers.
My 60s Truimph weighs 370 and the Steib 160, a good passenger can make a fast ride on curvy roads much better, and there is a great satisfaction in a ride where machine and two people co-operate to make it fast.
Up north our motorcycle club set up a quarter mile timed track by some railroad tracks and abandoned factorys. It was all sharp corners and low and second only. My passsenger and I practiced the day before to get the shift points and braking down, and she did a great job of shifting weght to where it was needed.
Then on race day the other sidecar drivers decided to run the course in the opposite direction- they had heard about our practice session and were afraid my ancient Triumph would bet their modern Guzzi outfits.
All my practice was for nothing and I was raving pissed off.
But the cops showed up and we all scattered- they confiscated our banners, road closed signs, and beer stand. But that is another story.

nice blog. dont understand a word but good pictures, and they are climbing mountains with their old zundaps. something inside me whispers Im a chicken not doing the same thing.

another thing. Im very impressed with the suspension on my new rig compared with my old velorex, but when I try to figure out how it works I come to the conclusion that a mc swing arm set up is not optimal. when I try to figure this out I normally end up very confused but anyway, somthing tells me that another solution would have been better. can it be put down into elemantary physics in some way?

suspension

No physics, just trial and error over generations.
Everything has been tried at least once.
Ease of manufacture (production engineering vs. product engineering) is the reason a lot of suspension systems are used.
And it's the reason a lot of home shop suspensions are so much more well-thought--out and better made than factory ones.
Your latest idea is probably worth as much as anyone else's.

sidecar language

Just look at the pictures, but German is pretty easy,
A sidecar outfit is "gespanne", as in a team or span of horses.
"Motorrad" is motor+radius, as in the radius of a wheel.
"Seitenwagen" and "beiwagen" are self evident.

Some pretty impressive repo and restoration parts on that site, I have to admire that guy. It's not easy to start a business in the former DDR.

When you align the sidecar. Do you also add weight to the tub? I did what RedMenace did with the strap and sitting on the bike but do we do the same in the sidecar to compensate for the weight?

weight

Some people use ballast for a while until they get used to the machine's handling, but after you know how it will behave, you won't need it.
Some people mount a car battery over close to the side wheel.

Load it the way you will use it the most. If you will have cargo or passenger most of the time, throw some weight in the sidecar when you do your set up

I have a very light freight boat, so I use ballast any time - with a heavier boat it's less necesarry

If you want another body design, then draw out your design.
Work it until you think you have something that you want.

Then show the builders & see what they can add to it, to better make it fit your expectations.
