@oleary
I really feel for your situation and side with your dissatisfaction about being forced to update without your consent.
As I have mentioned previously, the rear cylinder shut down thing should be option-able where it could be enabled or disabled by the user.
Hopefully, Ducati will re-update it as such soon to allow the owner to choose his preference although that does not help you right now.

Direct from Ducati

Idle (Neutral) and gear engaged and clutch lever completely pulled in (clutch switch pressed) – Coolant temp between 75-85C - Rear bank will disable after 30 seconds.

Idle (Neutral) and gear engaged and clutch lever completely pulled in (clutch switch pressed) - Coolant above 85C – Rear bank immediately disabled.


Note: My bike has the full Akra and the "Ducati Performance" software.

So I said, OK, if I'm riding down the highway at 120 kms AND I roll the throttle to idle AND the engine temp is above 85C will the two rear cylinders quit?

Ducati's answer? "We don't know"

Do I pick the bike up on Thursday - or not?

That is some straight crap. 167F is not that warm...while usually moving I don't get up there, it doesn't take long sitting around to hit that, or any sort of stop/go traffic crap will get you there quick...I'm starting to wonder if the demo bike I was riding around for quite some time had that update or not? If it did it was pretty seamless. Not a big fan of those numbers/situations though. Tough decision.

The cylinder deactivation will not occur if the motorcycle measures wheel speed.

So I asked,

Given your description of the system:

If I stop at a light AND kick the bike into neutral (as I always do) AND let the clutch out (as I always do) AND the engine temp is above +85C the rear cylinders should start up again, right?

It does sound like **** and if you don't have to worry about heat why bother with the "feature," it would be nice to turn it off.

Yeah almost makes me feel like one of them eco friendly jeeps going silent for a moment; but at least it engages quickly when you let out the clutch even the slightest. I was almost hoping it helped w/ the heat from the rear cylinders but can't tell the difference once it's already hot

I don't see this being that big of a deal. It probably won't sway me buying one when the time comes. But I'll sit here in the rafters and see what everyone thinks after experiencing this new mod. I don't really see it having much impact on performance. And at least they are working on containing heat.

They might be working on containing heat but get stuck in traffic and this bike gets really warm!

It's not a mod. If you haven't even ridden the demo you won't know what we're talking about. It's annoying that it can't be disabled. Yes I'm bitching. Is it a big deal? No. Does it make this bike any less fun? No. Honestly they are trying to deal with heat issues for the plebs IMO. Yes the bike is hot when you can't straight out 60+. It's what happens when you stuff 200hp under your crotch. I'd rather have it hot as **** (as it already is, disabling 2 cylinders probably doesn't do that much) and running on all 4.
