48 tooth clutch

FYI...Spareshack have launched a new brochure in conjunction with Daniele Moto...it's well worth a look- stacks of goodies on view, and of special interest (to me) on page 70, is a 48 plate slipper clutch made by an Italian firm EVR. Has anyone tried one of these? The text reads: Unlike trad slipper clutches (which allow the entire clutch hub to rise)...this Control Torque System operates by allowing only the clutch plates to disengage- allowing a more refined and reliable operation...bit pricey- at £794 plus VAT...and am loathed to risk anything 'unreviewed'..any advice welcome.

I've got an EVR normal clutch in my 996

Sadly its well past its sell by date

They are nicely made and well thought out. The pressure plate pulls air into the clutch to cool it.

The 48 tooth is also a lot quieter than normal clutches.

They also last a fair bit longer than standard ones.

I'm thinking about 1 too, clutch is next on the list and noise reduction is my main aim (although 'bling' comes in a close second!).

Nice to hear your comments, Crust, they are very pricey so all feedback is welcome, gotta start saving now

Bling although nice, in a lot of cases seems to add weight to the bike.

I've just fitted a 48 T clutch basket and plates to my S4, it's riding a new bike.
Quieter by miles, and smoother to pull away with.
I can't express how pleased I am with it
So spend wisely.
Cheers

Just out of interest, was that the STM 48 tooth clutch?

It was the Sigma 48T basket and plates, got it from Luigi.
Picci of basket here

Lighter than the steel item and tons quieter.

Why
Cos' if I wanted to ride around on a bike that sounded like an RD250 with small end failure and piston slap, I'd have looked for an RD250 with small end failure and piston slap on eBay.
Now I have an S4 that drives better, is quieter and ticks over smoother as it's not try to fight the inertia of 12 little tangs bouncing backwards and forward in their basket.
This will result in less stress to the associated drive train components, thus resulting in a longer life for all.
