Cheap chassis! I mean, they were economy cars! Honda et al do
a fantastic job at this, today, though I never rode in a early
70's Honda to know if they sucked too. Standards changed.

The Classic's really well insulated from road vibration. The
trans mount is usual, but the whole x-member is isolated. Spring
pads top and bottom front and rear (mine are long gone, though
I cobbled up something, I forget) and rubber in the panhard.

The Hornet, I really did a good job of heat insulation, air-tight
interior, and a fair -- but 400% better than factory -- sound
insulation job. With windows up, it's quiet, and cool; for
interior noise (wind, engine etc) it's not much worse than the
'96 Honda.

Though my exhaust is fairly loud, with that Summit turbo muffler.

The hornet is all road noise, thumps, rough surface, etc
all transmitted mostly the front, where the rear is just a
poor-weight-ratio longitudinal spring rear with no insulation.

I run decent Nitto tires, but maybe they're noisy, who
knows. It's not like I get to try 'em all out.
