Introduced only a few years ago, Progressive’s innovative 940 Series shocks became the go-to for Harley-Davidson touring riders looking to eat up big miles in bigger comfort. Now they tell us they’ve made them better with the addition of a new technology damper and updated the series to 944. What’s the difference? They say just about everything changed, beginning with a proprietary damper dubbed Frequency Sensing Technology for its unique ability to dynamically adjust damping as you ride.
FST (Frequency Sensing Technology) is described by their engineering team as like having two sets of shocks on your bike. One set to comfortably and efficiently smooth away those nasty exposed aggregate road surfaces, weather cracks and expansion joints, and a second set to handle the big jobs like drainage dips, speed bumps, bottoming control and cornering stability.
This patent pending technology features frequency sensitive damping circuits which enable the new 944 Series to deliver unsurpassed performance and comfort.
The one item that did not change from the previous generation is the combination of a progressive rate main spring with a flat wire compensator spring. This arrangement compresses under the weight of the bike, but readily extends when needed, to allow for full droop travel. The result is a bike with a 1” lowered height that rides better than the taller factory set up!
The new shocks feature all aluminum body, deflective disc valving, unique FST circuits and progressive rate springs. Like their predecessors, the 944 Series is preload adjustable by turning the top cap and can be easily set up for your weight and riding style. Available in standard and heavy duty spring rate and supported with a lifetime limited warranty. Contact your local Progressive Suspension dealer for more information. Progressive Suspension.
