How does a slipper clutch work?

So, in a nutshell, when the speed of the rear wheel is set to overpower the engine on downchanges that would typically unsettle the bike, it just forces the clutch plates apart?
In a nutshell, yes. Great for when you're changing down at speed and the back wheel usually snakes around behind you.
As an aside the new ZX636R gets one as standard which is pretty cool.
Had one on my old Aprilia Falco (same as Mille) you definately need one on a 1000 twin with all the engine braking.
Was interesting as if you changed down while slowing down (ham fisted stlyee) early without proper rev matching it would just keep the same engine note/revs constant until the rear wheel caught up quite a strange feeling to be honest almost a little freewheeling like.
A 600cc inline 4 is positively two stroke like with lack of engine braking (not really but seems like that initially) in comparison to a 1000 twin.

The milli one is not a slipper clutch it uses vac off engin to pull the clutch in, the one on mine uses 6 steel balls on ramps preloaded by a spring and as the rear wheel slows it drives the balls up the ramp.Thus pushing the plates apart so disconecting drive that is the clicking you feel at the lever. Still feels odd though.Being honest not rearly much use on road like you say more of a track thing.I used to slip the clutch going in anyway so you can back it in but now it just goes in then round. Good job i got it for free with bike at £800 not worth it. Still dont know if they all feel same bar milli.

I hate being driven by people who don't do this. I just cringe at their poor clutchwork. My old instructor (bike) always said good clutch control was fundamental to good bike control. Makes the ride for pillions a damn sight better, too.
I much prefer the Rekluse cluth on my Husaberg 650. No need for a clutch lever at all.

Are you sure the Falco has one?
My Mille has one. It doesn't see much use, though, since I always blip the throttle on downshifts - whether in car or on 2 wheels. I'm sure it would be a lot more use in the more intense setting of a track.
Well yes seeing as the engine is the exactly the same only restricted exhausts.. it has the same system
Irrespective of what anyone says it works as a back torque limiter so has the same effect as the ducati one.
As I had said it took some ham fisted un rev matched down changes to trigger the thing.
To be honest if you ride it properly I can't see how you'd ever need a slipper (or similar) system on the road unless ahemmm you are 'making progress' LOL
Anyway I've been shot of my italian irritation for over 18months now. My biggest mistake trying to commute on the thing. Stuff just goes wrong with constant use, don't get me started on clutch slave cylinders.
