Title: 2009 Monster 696 slipper clutch
Post by: alibaba on September 23, 2009, 07:21:03 PM
Does the 2009 Monster 696 have a 'slipper clutch'?

What would be the best way to check if it is set up correctly?

It has the APTC, which is kind of like a slipper clutch. It usually works out of the box and I don't think it's adjustable (?)
Testing how/if it works involves hard down-shifting combined with sudden clutch disengagement. That is, by definition, a dangerous maneuver - be very careful. Better yet, don't try it. It works to a degree, but when you find out what it's limits are - the rear wheel will skid.

be careful on oil selection as well. climate/usage/load will affect the clutch. talk with your shop on that one when you change your oil.

I think it does the job really well, only breaking with the 1st gear very aggressively would get the rear end do a little sliding from side to side in good weather conditions.

Here's a recent, more detailed discussion of the APTC
http://ducatimonsterforum.org/index.php?topic=29864.0 (http://ducatimonsterforum.org/index.php?topic=29864.0)

Basically... I can say from experience, you know when it's NOT there... Down shift throttle and clutch control are much more necessary when you don't have one, than when you do.

As far as adjustment - there is no external method for adjustment.. and since I sold my 620 tech manual along with my 620 I can't be sure if there's really any adjustment factor to it. But, I'm going to make a safe guess and say 'Not really'. It works well as is, in the stock form - and it's on the base line bike(s) do that added cost of making an adjustable unit was probably not high on the Ducati engineers to-do list.

Sure, the fancy race-bred true slippers can be adjusted... but those suckers cost a pretty penny.
