This Screamin’ Eagle Variable Pressure Clutch (P/N 37000121, $289.95) from Harley-Davidson Genuine Motor accessories is designed to enhance the performance of an original equipment clutch.
This bolt-on kit uses the centrifugal force of spinning weights to apply increasing pressure to the stock clutch pressure plate as RPM rises. Peak clutch tension is increased from 120 ft. lbs. to 153 ft. lbs. without increasing clutch lever effort at idle.
The Variable Pressure Clutch also provides smoother clutch disengagement at lower speed. This kit fits 1999-later Evolution 1340 and all Twin Cam-equipped models behind most stock derby covers with no modifications. Some covers may require a spacer kit. See an authorized Harley-Davidson dealer for fitment details. Harley-Davidson.
And why Harley doesn’t install it on its production bikes?
Once again, the aftermarket does HD’s R&D for them. I figured it was only a matter of time for these to go mainstream.
They do work incredibly well with no apparent downside.
My observation has more to do with the general concept: Why can’t they just spell S-c-r-e-a-m-i-n-g and stop with the cutesy stuff?
Screamin’ Eagle is trademarked. Screaming Eagle cannot be trademarked.
Where do they get these great ideas???? It’s like they have a time machine. Just set it back it time a year or two….
Okay….so where’s the unit for the 86 Evos?
copy cats.
Screaming Eagle belongs to the US ARMY and the 101st……
As usual, 2-5 years too late
