Theory of Riding Sidecars

Post by rougaroo » Mon Feb 24, 2020 11:26 pm

There's been a lot of discussion recently on alignment, lean-out, riding on curves, exercises, etc. This is a chapter from a German manual called Manual for Enthusiasts of Riding with a Sidecar by the (German) Federal Motorcycle Riders Association, and translated & published by the USSCA way back in 1988.

This has a great but technical explanation of some of the physics involved in sidecars, with some good and unfortunate illustrations of what happens if you don't get it right. Physics always wins. Also of interest is how the center of balance changes with various loads. All of this is stuff that is far different from a 2-wheeler and that you have to just practice, practice, practice to get right.

Worth the read:

That’s got me thinking about how to initiate three-wheel drift when turning right/into the sidecar. I watched someone doing this on highway 180 out of Suches, GA last August. It was impressive. (On the other hand he wore out one of the Duro knobby tires in two days/400 miles...)

Yep the CoG must stay within the "magic triangle". I was told by my tutor worst thing you can do is have a pillion passenger on and the sidecar empty. The CoG is very high and very close to one side of the triangle, if it goes outside the triangle (the line between the bike's tyres) you're off.

Forklifts in a different direction for the triangle.

I have the Ural manual for diving in a PDF, too large for the attachment but PM me and will send.

It's just a theory, I don't think it can be done. :lol:

Occasionally you'll see someone who thinks they'll take the family for a ride and they put the wife on the back and the kid in the sidecar. Seems semi-logical from a two-wheel perspective, but it's a recipe for disaster.

All of the Ural manuals, the Yellow Book, and other references are available for download in a sticky at the top of the "Ural/Dnepr 101 - Newbie Questions" section of the forum called "Sidecar Manuals for Newbs (and old pharts, too)"

There is a old manual circulating "how to ride a Ural" I once got it from our friend Marine by choice. its very good to. (might search for it later after work, because the IMZ-link is outdated....they should make it available again, because it has excellent recomendations for riding safety "look ahead!")

The manual you mention was my only guide for to learn "how to change from a 3 wheeled Austin Mini Cooper to a 3 wheeled Honneker-Taxi". After one Norway trip in December and several camp rides in winter I learned my lesson well. (and had my MZ rig severely damaged - 2 strokers do not like winter!)

In Spanish we made up a tutorial thread for rig riding basics in the spanish forum.

The link for "How to Ride the Ural Sidecar" is in the sticky titled "Sidecar Manuals for Newbs (and old pharts too)" at the top of the "Ural/Dnepr Newbies" section of the forum

I am purposely not listing the link in this thread to encourage new users to use the "Search" function here on SS. There is an immense amount of information here on Steeds. it is highly likely that (almost) any question you have may already have been answered - with pictures - in some previous thread.
