Harley-Davidson Sportster | IFP Rebound

Rode all day through stop-and-go traffic and highway stretches, and these shocks never faded or bounced — the nitrogen/oil separation really does keep the ride consistent.

The internal floating piston makes a real difference on longer rides—the rear end stays planted and controlled even after an hour of highway miles, with no fade in the damping. It's a noticeable upgrade in comfort over the stock setup, and the bike feels much more stable through the twisties.
