It all started in 1903 or there abouts…
The motor company went through a number of changes over the years with the way they transferred the power from the motor/transmission to the rear wheel. The one most commonly known looks like this:
Now, this clutch may have been the bad ass doohickey in the day, (and while there are still bikers out there that swear this clutch is the best), it just ain’t!
That old style stud and coil spring clutch had three major disadvantages that a diaphragm spring clutch doesn’t have.
The more you compress the coil springs to engage better, the harder it is to pull in the clutch lever in.
The friction plates ride up and down on the studs about approx. 1/8″ and wear grooves in the studs allowing the frictions plates to hang up on these grooves.
The needle bearings are trapped in a stamped steel retainer that is so sloppy it lets the clutch hub wiggle and wobble. The friction liner on the rear of the hub then tends to contact the rear of the clutch basket and that’s when the clutch pulls you through a stop sign with the clutch lever pulled all the way in!
Diaphragm Spring technology is the heart of our Comp Master™ clutch for Knuckles, Pans and Shovels (plus a few more). It just works better because; It’s easier on the wrist, it holds way more power and it is infinitely easier to adjust. PLUS….We replace all those itsy bitsy needle bearing with a double row automotive type sealed bearing housed inside a billet aluminum bearing retainer. Totally stabile with no more wiggle of wobble!!

Diaphragm spring makes it easy to pull in the lever and completely engages and disengages the clutch so its easier to get into neutral and easier to get into gear. This one’s for you!
