So talk to me about slipper clutches, are they any good?

I am specifically referring towards the standard one found in the Kawasaki ZX6R...

Typically, factory fitted slipper clutches are pretty crap. But it all depends on the intended use. If it's purely road work, they'll be fine. Track work?? Think again.

Having a big twin I find mine a godsend - its very rare I get my back wheel to lock up on the way down the box. That is on the road though (even though I'm bd fast wink )

i have an 06 ZX6R with standard slipper clutch and its certainly good enough for me on track.

I find it much easier than trying to brake and blip, as i could never get the hang of it.

I've always braked and blipped - never had a problem on track or off with not having a slipper clutch.

After years of riding - Not sure I'd ever feel comfortable wazzing it down 3 gears with the throttle shut and letting the slipper sort it out. I'm not good enough to have to dial out chatter and the like using a slipper.

Still - when it comes to mechanical and electronic rider and driving aids, I'm firmly in the luddite camp.

Now you see, I'd say it takes considerably more skill to blip going down the gearbox when you're hard on the brakes - I can only really do it when I'm not riding fast (thereby defeating the point). When the weight is over the front and you're leaning on the front brakes, I find it very difficult to blip the throttle.

My bike has a vacuum assisted slipper (only works on a closed throttle) and I can't say I trust it so I always try to match gear to engine and road speed. I don't always get it right but try to err on the side of caution and go for the higher gear.

The £6-800 that proper slipper clutches go for are a bit too much for me when I don't race and don't need that extra edge.

Not really read all of the above, so apologies if this has already been said, but... I;'ve had a bike of 2 with them on, and they are ok. However, my mate has a race spec type thingy on his 675, and it is fantastic. Properly brilliant. You can approach whatever corner you like at what ever speed you like, jump on the front levers, ram down the box, dump the clutch and plant your knee into the tarmac, before opening it up again..... Well, I mean you probably can...

I have a slipper clutch on my 999R, when pressing on (I mean REALLY pressing on) it nice to have but to be honest on the road 95% of the time its not needed!
On track it definitely is worth having! biggrin

Why is that my friend?
I'm guessing you read that grabbing both levers related to 2 clutches.....didn't you??!! Did you forget what the other lever is for??!!

Depends how the ramps are setup. When used hard, there is a wierd sensation of the clutch lever sort of 'vibrating' under your fingers as the clutch pack rides up the ramps to disengage. Also when the clutch re-engages, you get the effect of the revs rising slightly as you get pack on the power, which is a degree of clutch slip.

If you use a slipper a LOT, you will need to keep an eye on your friction plates in the clutch, as they can start to wear out fairly quickly....

slipper clutches sounds amazing. a little too amazing. almost like some sort of witchcraft. i just can't imagine dropping to a low gear after heavy breaking, letting the clutch drop out and the bike not locking up.. (assuming the gear i picked was too low)

nevertheless i want one. can't afford one though, so i'll have to continue my incorrect rev matching/locking of rear wheel for now.. i actually got told off for this at brands..

er, the bike will still lock up in extremis. The slipper clutch can only help so much! It doesn't completely disengage the clutch, just lets it slip, hence the name.
