A Dutch sidecar manufacturer called "EZ-S" offered wider front and
rear wheels for Suzukis a few years ago. The wide wheels allowed the
use of radial car tires
on sidecar rigs.

There were two EZ-S rigs at the Griffith Park Sidecar Rally that were
based upon
a GSX1100G and a 1200 Bandit.

I talked to Doug Bingham about using radial car tires on a solo
motorcycle, and, AIR, he said that he'd done it, but the handling was
spooky.

If I was doing a rear wheel drive motorcycle-engined version of a
three wheeler,
I would use the Renault Alliance front end that was used at both ends
of SCCA Spec Racers when they first came out.

I dunno what Spec Racers are using nowadays though.

But, if I was building a non-motorcycle engine three wheeler, I would
try to find a Japanese front wheel drive car that had an entire front
end with transverse-mounted engine and design the car around that...

I'll buy that for a dollar. Thing is it appears those will lean more
than a auto or a side hack. IIRC isn't this story a over a year old
re: these particular vehicles?

With equal length upper and lower A-arms, there will probably be a lot
of camber change.

But it looks like the designer already figure that out and there's a
lot of negative camber evident in the set up. which is what you'd see
in the front end of a
GP car which had smaller front tires and larger rear tires.

And, the designer may have already used really stiff springs in the
front end, sacrificing suspension compliance for roll stiffness...

How?
