does the legend air shock give you that sit down effect when going over a bump (usually 80/20 do that, but their hard to find) .. or does it just pop you up.. like a pogo stick?
Depends on how much air you have in the system. Low pressure and its like riding on a 2 X 4. Too much and you bounce. I haven't figured out where I want to put a gauge yet so it's trial and error right now.
I run Legend Air on my 2011 Dyna Superglide Custom. I do not have any pogo effect with Legend's system. When my wife is on the back and we hit a large bump, she may go up slightly once and then the system levels out so it is just a slight bump at first and then no recoil. Just smooth and steady. And this is on the big bumps. Little bumps are not felt at all. She loves it and so do I. Well worth the money. My only issue is making my front as smooth riding as the air shocks on the rear.
I ran legends on my SG on a trip this spring. Seemed like about 62# for solo riding worked pretty good. Might have to raise the psi a little for 2 up. They worked great for riding in stop and go traffic. just dropped most of air out and it was so much more stable. Loved them.
I'm running Legend on my '011 Triglide. Maybe a 10% improvement from stock. To be fair, would get a better ride if I weighed around 225lbs.; running around 60-65lbs. A/P. Still a big fan of "Progressive" shocks.
