I just acquired a 2022 Royal Enfield with a Cozy Rocket sidecar. I also have a Ural cT that I managed to dial in so that it tracks well and is steady. The Royal Enfield had only 34 miles on it! The person who bought it new apparently didn’t like it and traded it in for a different bike. The problem is that it is a bit twitchy, especially in a strong wind, and has a tendency to rock back an forth. I have not checked the toe-in and leanout, nor have a checked the suspension adjustment, thinking I would seek your advice as to where I should start first. I am 79 and have given up riding two wheels due to a slight balance issue that is a result of years of Meniere’s, which is now pretty much burned out. Naturally, strength is an issue at my age. I’m being extra cautious in this regard. I am 6’ 4” and 260 pounds, which probably matters. What do you think?
A free opinion?
Why not.
My guess would be suspension in general and spring rates in particular.
That is if basic setup is good.
Potential solutions?
Fork spring upgrade and experiment with fork oil weights.
Most likely changes rear shocks for heavier sprung and better damped quality units. Likewise with the sidecar.
We will be very interested as a collective as to what you do and how it works out.
I do know it's very satisfying to get your rig setup properly and frustrating when it not.
Oh and photos please or it didn't happen.
Sounds like a pretty cool rig.
Agree with Bruce. Maybe start with checking/setting sag. Change springs as needed. Then a good sidecar setup to include sidecar wheel lead.
There is a very good article on setup in the archives on this website.
Best wishes for success.

@Phyman1946, I hesitate to give you my thoughts and opinions, as I am a little too frank and forthright (oh, who are we kidding...I am a LOT too frank and forthright)
On the polite side of the thoughts, add 150 pounds of sand tubes to your sidecar. Go to Home Depot or Lowes, and buy 3 of their 50 lb tubes of sand, as though your 1976 Ford can't make it up the snowy hill, and rather than buyer a more modern Subaru that has AWD, you elect to add some weight to the trunk of the '76 Ford, to help get you up that snowy hill.
Example: I just added a TOTAL of 240 lbs of weight to my Ural sidecar tub and chassis that is attached to my 2018 Honda Africa Twin w/DCT trans, because the sidecar was too light, given all the other parameters of the rig.
On the less than polite side of the discussion, you are a 6' 4" man, weighing 260 lbs, and you are trying to drive a sidecar rig that is UNDER-sized for your body. When YOU, the operator are a giant compared to the puny Royal Enfield and Cozy sidecar, that affects the physics of how the rig operates.
All kidding aside....and yes I am being serious....buy the 1995 Honda Goldwing 1500 SE with sidecar that Steve Ives is selling for a paltry $ 8,000., then sell your Royal Enfield w/Cozy rig for....$ 8,000......and you will be a happier man.

Which Enfield model is it?
I have a cozy mounted on a Classic 350. The entire rig is so light, I'll feel it twitch in high winds, but not in unexpected ways for my experience. Overall mine runs straight and is extremely easy to steer. It's also slow enough that reaching 65mph is only possible when I'm drafting behind tractor trailers, and that's after I swapped out the cylinder to an up-bored 411cc too.
The prior comments may have a point though, I'm only 5' 9" and probably 150lb soaking wet with all my gear. I have about 50lbs permanent ballast tied to the sidecar chassis next to the wheel mounts, but it's still light enough I sometimes feel the wheel hop on tight left-handers. Compared to me, you might need a Lot more weight in the car to make it settle, even after you get it aligned and toed in. After all that weight addition, you might also need a miracle to break past 50mph though, so maybe take some thoughts on where you intend to ride at that point
