Title: 620 Owners Manual: 60hp @ 9500rpm, elsewhere: Do not exceed 9000rpm?
Post by: positivecarry on November 28, 2009, 11:08:45 AM
So I was flipping through my trusty owners manual for my 2005 Monster 620, when I noticed that under the "Technical Data" section, it says that the Maximum Power at Crankshaft (60hp) is achieved at 9500rpm.

However, in the "Directions for Use" section, it states that after the running-in (after 2500km), "never exceed 9000rpm during motorcycle standard use."

So, seems like a bit of a contradiction...also odd it doesn't differentiate that 9000rpm ceiling for the 800 or 1000 Monsters which are also covered by this owners manual.

So, what is the true redline?  Obviously I'm showing that I've never really pushed it up there...but come on, I'm just starting this whole motorcycling thing!

You really can't over-rev a Ducati.

They run out of power/breath long before their ability to rev.

Also, all FI bikes have a rev limiter built in to the ecu, so that will be the limit.

The DP ECU takes the redline north to 9500 or 10500 i think. i did some research when i was deciding about the 696 upgrades and found out 10500 is a good redline for 800 and 11k is for the 750 for the race prepped bikes. so safe to say 9500 for the 620 is ok.

the overrev is different for Ducati's then say a springvalve motor. you actually can reach the materials limit if you rev REAL high. but it's different for each motor

just warm your bike up, and on idle, rev it up until it bounces. thats youre limiter. if you make power beyond that? your power probably drops sharply before you hit that point.

'03 M620 manual says not to exceed 10,000 rpm.

IIRC, folks have said that the rev limiter is at 10,500 or so.
This is confirmed from a dyno run:
http://www.bikeboy.org/620sport.html (http://www.bikeboy.org/620sport.html)
It's *very* abrupt, so if you're going to check it while riding, be prepared.

Peak power on a 620 is somewhere between 9,000 - 9,500, not a lot of point in spinning it further.

i think my 620 the fuel cutoff is somewhere around 10k or so.  basically once you get past around 8700 the bike wont feel liek its giving you anymore, it will rev up to 9500 but at that point it doesn't really feel as though the bike does anything more.  i'm sure you have felt that it feels like the major push is after 7k or so but once you get near 9k that push is gone.

wondering what does that 9k rpm on a M 620 give you?

110 ? 120mph?

I've only rev to 8k and it's just about 10x mph ( not entirely sure since i have to keep
an eye on the traffic so i dont get killed)

completely flat and straight, 5th gear that is the top gear on my 620 gives you indicated 110 at about 8500rpm and the rpm slighty moves but it takes (2-3 sec per 100 rpm) .

One other thing to note, the Ducati rev limited seems fairly drastic when you hit it.  I've hit it on other bikes and it's usually a stutter and loss of power.  With my 800 it goes from smooth sailing to feeling like I just blew the motor, very abrupt.  Scared the crap out of me first time I hit it mid corner.

No offense, but why the hell would you be near the limiter mid corner?

None taken ;)  Bike was new to me, not used to what the engine sounded like.  It kept pulling, I kept revving.  It didn't sound like it was near redline.  Couaght me offguard a couple of times that day, haven't hit it since I don't think.

I've found my Monster to be much better behaved lower in the rev range.

I'm a 2 wheel kind of guy, and believe you go faster a gear higher.

I think everyone should try it. ;D

I've hit my rev limiter (9500rpm) on my '08 M695 a few times and usually if I am pushing the bike that hard, I know it's coming.  The first time I hit it, I was in 2nd gear really trying to speed up quickly and it scared the living daylights out of me.  I thought I was going over the handlebars for sure. 
I've heard with the Termi ECU, it raises the rev limiter to 10500rpm, which for me, would be better.  Anything above 8500rpm and my bike is literally screaming for mercy upshifting.

My M695 with the DP ECU/stock gearing hits the rev limiter around 85-90 mph in 2nd gear.

I've never done it by accident. ;)

I've hit the rev limiter on my 05 M620D on the first 3 gears and hit a top speed of 133mph[as per speedo]@97XXrpm... Got very very close to 10K but that was on a straight that's about 2 kilometers long. Usually I don't go beyond 6k~7K...By the way, stock ECU, 15/48, Termignoni slip ons, open top airbox.

That's exactly what I did my second or third track day.  I was all amped cuz I was in the midst of passing some guy.  And like Scott, I didn't realize how close I was to the limit.  Hit the limiter mid-corner where it came on ABRUPTLY.  I stood the bike up and shot off into slick wet grass (where you can't brake) and then into a tire wall.  <sigh>  Some people learn stuff by figuring it out or reading it on the internet and then putting it into practice.  I learn stuff the hard way -- doing it, crashing and then trying not to do it again.   :'(
