Slipper clutch

[sycomoto]

I know

Except it has RT wheels and road tyres

More impressive is Vern or Mutters on TKCs

I was taking the piss dear boy

 

[Flipfly]

I've tried to keep up with old bearded wonder when his TKC's were just about shot....impossible. You need to add the late Bobble to the top of that list as he was better than either of them on TKC's

Bobble.....lovely rider

Had a day in the lakes having a fantastic ride out with him a few years back, shmooooooooooooooove

 

[Callard]

True, but the fun of the 1150 is everyone expects it to be slow which pisses em off more. Everyone knows the LC is fast, so if you can't keep up you only have yourself to blame

I had no idea they were that slow. Plus at those angles of lean doesn't matter what tyres they are.

Oh F@ck . . .

I think the slipper clutch is great on the new bike you use it to ensure you have the maximun amount of grip at the rear , which stops the hopping action of the rear wheel ( suspension ) when pushing hard into a fast or tight corner under bracking , the cluch will allow the engine to absorb the extra revs as you change down to get to the best gear in the corner. This means the rear is in full contact with the road and the suspension is settled.
Try say approching a corner you know ( a typical 60 corner but attack it at 90) the change down several gears , and you will find how much more settled the bike is , also the power is instant as you are carring more revs , and lets you exit the corner quicker , i know the slipper clutch is for racing but if you ride with spirt you will find that you can hang off the back of much faster bikes as the bike is so settled.
Some may not need or even use the slipper but for some its a great addition to a brillant bike IMHO.
Sorry if my technical explanation is not perfect but only pointing out my observations as have several slipper clutches on different bike (KTM 990's) .

That all makes sense but it would seem that for the majority or riding, particularly on a GS, you develop a technique that use the engine braking... Then on those occasions when you really go for it you need to adopt a different style which is OK except when going for it means the different bends and road conditions straddle the point when it will kick in.

.... I'm glad my Airheads not got a slipper, I'd never stop the old girl

 

[Jumblemo]

In 2000 miles on my WC, including some aggressive hooning around the hairpins of the Black Forest, I didn't trigger the slipper clutch once. Personally I'm very glad it's there, but unless you have no mechanical empathy for the bike at all I think it's unlikely to come into play. So maybe more balanced use of clutch, brakes and engine braking is required?

 

[Blackal]

It's mostly there to prevent numpties locking up the rear when changing down too enthusiasticaly and lots of bikes seem to be having them fitted as standard nowadays, especially sports bikes.

I've never ridden a bike with one either but have to say, in theory at least, I don't like the idea - I want to be able to dial in some heavy engine breaking and even a little lock-up at times.

"Dial in". .

Dial in a bit of preload on suspension, perhaps (even then, you could be accused of 'sexing up' the script) - but 'engine braking?....... Puhleeez!

The new bike is noticeably more stable under hard braking than the old one, one of the many benefits of the new bike.

The slipper clutch is perhaps not strictly necessary but with the increased compression ratio I find the engine braking greater than than my old twin-cam, so a slipper clutch makes more sense on this GS than any of the previous ones - provided BMW have got the design compromise right then it effectively modulates the clutch for you when one is riding in a sporty manner, just in case you forget to do it yourself.

Does anyone know if it's a mechanical or pnuematic (sp?) slipper clutch.

My Tuono had the second type (I'm not spelling it wrong again!) and it was great under certain circumstances*.





























* Barrelling into a corner, completely misjudging it, stamping down the gearbox, grapping a handfull of brake and praying to whatever deity to happen to subscribe to.

I believe that it is mechanical.

 

[Engineer]

Just checked BMW's press release document and it says that it is mechanical ramp mechanism.

Would disagre as the clutch will work without you really knowing , its not that its a ' blimey ive just done that corner fast ' wow the sliper clutch is great ' is the fact that it is allowing the bike to be more settled in the corners as you changedown , ie using the engine brake etc without upsetting the rear suspension . You will notice it a lot more if you ride with passion.

 

[Jumblemo]

I only ride with passion ;-)

 

[Jumblemo]

But assuming you didn't realise that the slipper clutch is there then you would expect the bike has the capacity to lock the rear wheel on over aggressive down shifts.

And, despite an earlier comment from another on the forum about his predeliction to 'dial in' (really?!?) rear wheel lock, I make it a policy to avoid locking up my wheels even (especially?) when cornering with passion. So if I achieve it, it is in error and not by intent. And personally I'm happy to take assistance from any technological system available when I make an error.

Not quite what I said was it; I mentioned wanting to use 'heavy engine braking' and 'occasionaly a little bit of lock up'. This usually applies to general arsing about, hooning and off road.
I certainly would not want to lock up a wheel when cornering 'with passion' (whatever the feck that is ) and despite having raced Supermoto and Hill Climbs I still can't back in a bike consistently (not that you lock up any wheels to do so).

Fair comment

I used ot ride like a twat on Honda Sprts bikes which had slipper clutches and they do add safety by stopping lock ups with aggressive down changes... Years ago I back to back rode my old CBR6 and then a ZZR6 along the same fast stretch with a fast decreasing radius bend approached under heavy braking at the end... No slipper clutch on the Kwak and having the back coming round at about 70 was a bit hairy scary with the bend tightening...

Perhaps the LC one is "runnig in" and will become less sensitive as it gets some miles... It's a bit like the heavy braking ABS "glide" on ABSII bikes... Sort of feels like its speeding up even though it's only releasing the brakes slightly....
