Each spacer goes below the spring cap, so it reduces spring preload. Just think about how it all goes together. It's an old trick to ease the lever effort. It most certainly does not increase the preload.

Here goes.

I have a Speedymoto cover now, to go with my Rizoma pressure plate.




While I was awaiting delivery of the cover I rode without anything to protect the pressure plate and grew to like the look.  I'll see how I feel about the new cover but may end up taking it off again or going for something like the CycleCat DCC10's ( http://www.cyclecat.com/billet/clutch-covers/item/94 ). We'll see.

You inspired me, although mine is not as gnarly looking!




I also picked up your run of the mill Speedymoto 10 spoke because it shows off the Rizoma bling a little better.

Do these aftermarket pressure plates render any notable performance advantages?

Yeah, they perform better. 

My combo was posted by someone else already...




But this is the one I wish I had:  homemade from someone on TOB several years ago.

How do aftermarket pressure plates help with performance?

They improve stationary speed by like 10-15%.

Potentially lighter (sometimes not - many are heavier than the stock plate) and reductions in rotating weight are always good.  Biggest advantage is from the variety that protect the spring-posts when using an open clutch cover - reduces damage if you have an off.  The open clutch cover itself offers the benefit of cooler clutch operating temperatures.


if you are going to upgrade the pressure plate, do some price checking and consider doing a slipper clutch instead. Don't worry - it comes with a purty billet pressure plate too, but offers significant improvements to function.

Thanks

$hitty picture, but here is an open clutch cover my machinist buddy made for me using the one on the right as a template. Started as a bit of a joke but it turned out so well I love it! Going to probably paint it black but will see. Now I have to get a new pressure plate too!

Any way you could get the CAD file??? I will be trying to make my own as well. To mathch the cut-out on my case.
