Hi,
I thought I'd share some images with you of two counterweights I have put on my sidecar with the help of a local engineer. I'm sure there are many solutions but I thought I'd share mine with you. The first counterweight is attached to the sidecar footplate and weighs approx 5 Kg the second counterweight is attached to the sidecar frame and sits out towards the sidecar wheel it weighs approximately 7.5 Kg, so combined weight is 12.5 Kg. After a test ride around my neighbourhood I found that the handling had improved considerably and the tendency for the sidecar to lift in left hand turns, remember I'm in Australia has been significantly reduced. Hope this helps!

   Works out to just under 28lbs U.S. (12.5kg)
   I haven't received my car yet, and had considered a couple of 5 gal jugs as counter weights (about 60lbs/27kg), but I like your suggestion, too.It would free up interior space, and eliminate the need to remove the jugs for the missus. :)
   Thanks for the pics, and welcome to the forums!

   Which make and style of car do you have?
   Is your car mounted on an RE?

I added counterweights to my sidecar by placing several tools, new chain, new sprockets, small bottle jack in the trunk, I be will fitting a 3l Jerry Fuel Can with fuel to the car between the bike and sidecar later this week.

          Wouldn't your 5 gallon jugs be closer to 40 pounds each?

Those weights are interesting...  ::) and a cable brake! Very clean installation.  Does having them low to the ground increase thier effect?

When riding solo I use 3 cases of bottled water in the interior, (I was told they're 20 lbs each) and a solid steel 35 lbs curling dumbell in the trunk, with two canvas bags of tools, and scissor jack!  :P Unexpected sidecar flying...not a problem! :o

   You are correct. At 8.34lbs/gallon it works out to closer to 83.5lbs for a couple of 5gal containers.
   Brain fart on my part using Jet-A weight/gallon (6.8lbs). Bad habit.  :-[

   Re-thinking the counterweights (and inadvertantly prompted by a post above) the tools I normally carry and maybe just one 5gal jug should work fine.

   Today's the day to be delivered! YAY!  ;D

The only time I find counter weights may be needed is when my super mean 36 pound Suzy decides to play with the neighbor dogs instead of riding, which is very rare. At those times she thinks she is a dog instead of a human with short fingers, long nails all around and extremely furry all over the body.
