If you've ridden a modern Harley-Davidson motorcycle equipped with a cable clutch system, you probably know how fatiguing that clutch pull can get—especially during slow-speed maneuvers, stop-and-go traffic, or long days in the saddle. In this article, we’ll introduce you to a game-changing upgrade: the Mueller Power Clutch 2.0. We’ll also walk you through the key elements involved in upgrading your cable clutch system without getting bogged down in every bolt turn. (see video below)
Why Harley Switched from Hydraulic to Cable—and Why That Matters
For years, Harley-Davidson touring models came equipped with a hydraulic clutch system. Then in 2021, they shifted back to a cable setup. While cable clutches work, they can be inconsistent from bike to bike, require regular adjustment, and provide a stiffer, less linear pull—none of which screams “premium.”
Hydraulic systems are consistent, smooth, and require no manual adjustment. That’s why many manufacturers still rely on them—and why riders often feel let down by Harley’s regression.
The Problem: Plastic Clutch Adjusters
If you're riding an '18 and newer Softail or '21 and newer Touring model, chances are your clutch cable includes a cheap plastic inline adjuster. Not only is this piece prone to failure (and can even leave you stranded), but it also offers minimal fine-tune capability—just a red button that automatically adjusts based on spring tension. It’s more “auto-manual” than anything else.
The Solution: Mueller Power Clutch 2.0
Welcome to the Mueller Power Clutch 2.0, a precision-engineered German-made upgrade that transforms your clutch feel. This system replaces the stock plastic housing with durable aluminum components and an adjuster. And adds a custom ramp mechanism internally. The result?
-
Up to 45% lighter clutch pull
-
Smoother, more linear engagement
-
Enhanced fine-tuning of friction zone
-
Elimination of plastic components that commonly fail
Whether you're dealing with arthritis, small hands, or just want to reduce fatigue on long rides or during training drills, this upgrade is a must-have.
⚠️ Beware of cheap knockoffs – Mueller invented this system. Others have tried to copy it but fall short on performance, precision, and reliability.

Three Killer Clutch Upgrade Options for Your Harley
Depending on your goals and budget, here are three solid options we offer at the Law Abiding Biker™ Store:
1. Fat Baggers Easy Clutch Adjuster
Replaces just the upper plastic adjuster with a metal unit that includes a lock nut for fine-tuning. A huge upgrade over stock and super affordable. Pair it with the matching lower metal housing to ditch all the plastic.
2. Fat Baggers Complete Upper Clutch Cable System
Gives you full adjustability at the clutch housing—no more hopping off the bike to tweak settings. Plus, it eliminates all the lower plastic components and moves the adjuster right where you want it: at your fingertips.
3. Mueller Power Clutch 2.0 (Featured in Our Install Video Below)
The ultimate solution. It not only replaces all plastic parts but also drastically reduces clutch pull. This is the system featured in our full install and test video below.
You can even mix and match a bit—using Mueller’s ramp and housing system with a Fat Baggers adjustable cable up top for the best of both worlds.
Optional (But Awesome): Add Adjustable PSR Levers
To fine-tune your clutch and brake feel even more, we highly recommend adding PSR adjustable levers. Whether you go with the Anthem, Anthem Pro, or Journey models, these levers let you tailor the reach and engagement zone to your personal preference. For riders with small hands or specific needs, this is the cherry on top.
Real-World Testing and Police-Grade Confidence
As a police motor officer and instructor, I don’t just recommend products lightly. I put them through real-world drills—including tight cone patterns and low-speed maneuvering. The Mueller system passed with flying colors, making it easier to maintain the friction zone and stay in control of the bike.
And yes—we even did a (somewhat unscientific) pull test. My stock clutch pulled at about 27 lbs of force, while the Mueller-modified clutch came in at just 16.8 lbs. That’s roughly a 38% reduction, and you can definitely feel the difference.
Final Thoughts: Why You Should Upgrade Your Harley Cable Clutch System
A stiff, inconsistent clutch doesn't just cause fatigue—it can actually make you a less confident rider. Whether you’re navigating urban traffic, doing parking lot drills, or touring for hours on end, a smooth, easy pull makes all the difference.
The Mueller Power Clutch 2.0 is the best way to modernize your Harley’s outdated cable system and make it feel like it should have from the factory.
