When the piston size increases but the amount of fluid being pushed to activate it doesn't you get less travel on the piston with the same volume of oil at the lever, will affect clutch throw and maybe shifting depending on individual bikes, wear and existing adjustments. Same premise as changing brake calipers with bigger pistons, needs a mastercylinder change to compensate, all about volume of fluid.
Love the idea but we'll see as some feedback comes in.

Over 30 years of racquetball have taken a toll and I have chronic tennis elbow and I'm left handed. I still play twice a week so no chance of it going away LOL. A lighter pull would be less painful so I am really interested in this. It's not a big deal unless sitting in traffic a lot or doing low speed drills in the friction zone - then it would be nice to have a little less resistance. Like I said a "nice to have" not a "must have"...at least not yet.

I expressed my concern in an email to them and this was their response:
We are aware of the piston stroke length and we have done extensive testing to insure that there is more than enough stroke to account for proper clutch engage and disengagement. All measure of have been taking with great concern when engineering our product to work in all circumstances.

I believe you are right. The friction point would be moved closer to the hand grip.
I also believe the friction zone would be wider, similar to the way it was with the cable operated clutches.
There is more than enough extra throw with the stock slave cylinder now to disengage the clutch.
Reducing the throw would not be an issue.
The reduced effort on the lever force is an added plus.

I’m looking forward to seeing the reviews on this, my 60 year old arthritic hands let me know they ain’t happy after a long day, and can use all the help they can get - subscribed!

Went and visited my Indy today. Paid for my winter storage. Told them they would probably be installing this on the bike for me. Had an Aim VPC on my old bike. It was the best thing since sliced bread!
