Title: Clutch pull
Post by: skorch on April 15, 2018, 06:41:37 AM
I plan on handing down my 2010 CVO street glide to my wife but after riding it for quite some time she complained about the clutch pull too difficult. I have an easy pull  kit in her 2007 cable operated bike and it is definitely easier than the hydro clutch. Does anyone know if it’s possible to make the hydro clutch easier?? :-\

One way to reduce the clutch pull effort is to use a lighter clutch spring in combination with something like a VPC pressure plate.  The VPC (variable pressure clutch) uses centrifugal force to apply more pressure to the clutch plates as rpm's increase. This will result in a lighter effort clutch pull at idle and low speeds, but that effort will increase as rpm's increase.  Assuming she doesn't do a lot of 6000 rpm shifting, that shouldn't be an issue.  There are many combinations of VPC and spring to suit different purposes.  If the bike is basically stock then the VP68LT model of the AIM VPC is designed to reduce clutch pull effort approximately 40% and still provide the clamping force to prevent clutch slip.  There are other models for people with modified engines to suit the torque output of those engines.

There were some threads on this site back in the 2010 - 2012 time frame talking about this very issue, and if my memory was better I'd be able to tell you the name of one lady on the site who did this modification and was very happy with the result.

My wife’s 2013 SERG has the SE 3 Spring clutch and it holds 135+, the pull is super easy.

Thanks for the info..installed one and it works exactly as advertised. Wife is happy with clutch.

Take a look at these. I rode a KTM dirt bike with one and could not believe how well it worked.
