1100 Evo Slipper Clutch & Engine Braking

Discussion in 'Ducati General Discussion' started by richgilb, Apr 24, 2016.

  1. I rode an 1199 this week and the lack of engine braking was great. The owner said it was bad when he first got it but he was able to adjust the level of engine braking via his dash. I assume that changed the amount of engagement of the slipper clutch when shutting off the throttle?

    I then thought about the slipper clutch on my air cooled 1100 EVO. Which seems to do nothing of the sort that the Panigale does when rolling off the throttle. It seems more programmed to chuck me off the bike than anything else.

    Any tips, please? Other than learn to ride properly, it's a Ducati, what do you expect, stop being a whingeing pussy etc....

    I believe there is a spring that can be adjusted? I wonder what the standard factory setting is? Loads of engine braking or hardly any? And is there any detrimental change in other areas of clutch performance if I adjust it so it reduces engine braking as much as possible

  2. Bump, anyone?
     
  3. Not sure that any pre Panigale bike has that function. My 1098R certainly doesn't. Andy
     
  4. Engine Braking Control (EBC) was introduced in 2013 on the 1199 Panigale. At launch in 2014 the 899 also had it. EBC does not appear to have been included in the specification as standard in anything other than the superbike range. Andy
     
  5. EBC is completely separate from the slipper clutch. It uses the electronics to vary the engine braking by opening the throttle very slightly when the hand grip is in the closed position and the bike is decelerating. There are three levels plus 'off'.

    If you just have a traditional slipper clutch, you can vary the amount of engine braking it tolerates before it starts to slip by varying the height of the clutch pack (friction plates and steels). Slipper clutches on dry-clutch bikes are not maintenance-free; they need regular attention to keep them working sweetly. They can also be bitches to set up; the one I had on my old 748R worked well, but when I transferred it to my 1098S it worked well on the track but was a slip-grab-slip-grab monster at junctions and traffic lights etc.
     
  6. It's an Electronics thing, you can't do it on your Evo.

    And why would you want to ?!

    You have the best slipper going, just use it as intended: brake, clutch in, dump 3 gears, release and turn :)
     
  7. My slipper clutch is wet....so, OK, the engine braking on the Panigale is not about the clutch. Fair enough. So if people say that one benefit of having a slipper clutch is that it is possible to reduce engine braking, then it must be that Ducati choose not to take advantage of this benefit.
     
  8. Unless you have replaced or modified the clutch the standard clutch on the 1100 Evo is not a slipper clutch as far as I am aware. Or if it is, I haven't noticed.
     
  9. The M1100evo definitely has a slipper clutch. It is definitely more difficult to lock up the rear on downshifting than the M1100, but it's still not difficult to get the evo to do it. As far as I am aware the amount of slippage it provides is not adjustable.

    This is a bit of info I found about the evo's clutch:

    The Monster 1100EVO uses a new style of slipper clutch specially designed for the “wet” clutches of larger capacity engines. It features an oil bath system with ‘slipper’ function and super-light feel at the lever. Its design uses a progressive self-servo mechanism that presses the plates together when under drive from the engine, enabling the reduction of the clutch spring rates. This results in a much lighter clutch lever at the handlebar, ideal in traffic or long journeys. When the drive force is reversed (over-run), the same mechanism reduces the pressure on the clutch plates, enabling them to provide a race-like ‘slipper’ action which reduces the destabilizing effect of the rear-end under aggressive down-shifting and provides a much smoother feeling when closing the throttle or down-shifting under normal riding conditions.
     
  10. Haha my point exactly!
     

  11. This is the bit I want to know more about, because there's no noticeable effect of engine braking reduction there. I

    If it is not adjustable then will an after-market slipper clutch get me what I want?
     
  12. If you want less engine braking then I would have thought that a lighter flywheel would be your easiest option, although there are pros and cons for such a modification for a road bike. Also an aftermarket slipper clutch might be adjustable or just by default provide more slip than the Ducati one.

    Personally I liked the engine braking on the evo ;)
     
  13. My mistake! Clearly my downward gear changes are so smooth & well-timed that I was unaware of the technology. Either that or the slipper clutch is very good at flattering my riding technique.
     
  14. Yes, OK then!
     
  15. So not present on the Monster 821 then?
     
  16. Under normal riding you wouldn't notice any difference with a slipper clutch, it's only under very aggressive use that it comes into play, as has been said previously by knocking down two gears and dumping the clutch, then it will prevent over reving the engine and or locking the rear wheel.

  17. You are still confusing the clutch with engine braking, as its designed to stop the rear wheel locking not reduce braking. That is an extra electronic bit of kit. I would be amazed if the m1100 didnt have at least an ATPC (or whatever the acronym is) as the old 620 did. Its not a full on slipper but helps in reducing rear wheel lock up
