Must be an American thing.
You fit LEAF springs to your cars.
Come on, that's wooden cart technology.
When I was in Canada last month I rented a new Ford Edge.
I was surprised. No axle tramp, minimal lean when cornering and a nicely neutral feel through the steering.
Guess what,.... no leaf springs!
For an SUV it drove really well.
I think it's part of your compensating for only having a few hundred years of history.
If you drive/ride something out of the history books then you feel more in touch with your ancestors.
Given the crappy brakes/suspension you may make a much closer acquaintance with the same ancestors than you really wanted.
And before anyone starts in on me as a "stuck up Limey",....... yer right! <LOL>
And yes, a few of us do ride Hardley Fergusons as well as old brit bikes and even a few old "rice burners".
Me, I'll ride with anyone who can keep up.
