99 M900s Redline?

[TreyRiser]

I am new to this bike...love it, but absolutely dont know the limts... My question is probably pretty obvious but is there a danger zone associated with higher RPMs on my bike...the tach goes up to 12,000 and  then stops, i already assume i shouldn't go higher than 12 but how high is okay...i don't want to blow the engine?

9k roughly is the redline.  For some reason ducati does not mark the redlines.  If you ever were able to get the 900 engine to actually rev to 12k it it would probably explode in to thousands of little bitty 900 pieces.  You wont see much power after about 8300 rpms and you will feel the drop in power well enough to tell you it is time to shift.

Agreed.  My 99' 900s has the power begin to drop off around 8300 rpm according to the dyno sheet.  That's w/ hi comps, 41 flat slides and upgraded ignition w/ the programmable module.  You should have max power between 6&8k, any higher is unnecessary.

with the valve system in a Ducati there is no red line ............in theory you can rev as high as you like


that being said you have a rev limiter that kicks in at about 9200


plus there is also no point reving past peak HP


so thats why there is no red line on a Duc

Thanks for the info... i be sure to shift around 8 then... i figured it wasnt suppose to go to 12 anyway...i have only 500 miles on it and i am still being pretty careful because this bike has a bit more kick than i am use to..i hadnt hardly went past 7000RPMs...thanks again

No rev limiter on the carbies

For some reason ducati does not mark the redlines.

If you have the right model you get a redline.  My 888 tach looks like this:

Unfortunately it's not real accurate (although not as inaccurate as the speedometer), so the rev limiter kicks in before an indicated 9500 rpms, although the dyno run that was done for the bike goes to 10K.

One thing that I like better about the ST2 engine (and more so on the 888) is that it pulls strongly to redline (e.g., to rev limiter).  The Monster engines bother me when they start to fade when you rev them up.
