Rpm

[Ninja007]

Hi everyone,

What RPM should I have my 2006 Ducati Monster 620 on when I am going around the city? The manual says don't go past 7000 RPM, but it does not state what RPM you should cruise at. I am guessing somewhere between 2500 and 3000, but if someone could confirm this information, I would greatly appreciate it.
Thanks!

Actually, whatever rpm you feel comfortable with, however most Ducatis
don't like lugging along below 3000rpm. Even my ST2 with that boat anchor of
a flywheel chugs its resistance to that speed. My M750 seems happy as a pig
in the 4-6000rpm range. Also as an interesting side note: all engines are
at their most efficient at peak torque rpm. That's an interesting tidbit the next
time you bet your buddies you can beat their gas mileage. Not sure exactly what
rpm that is for your model. It'll be in the handbook. Probably somewhere around
6000rpm. Now get off that damned computer and go riding, it's nice out.

Thank you for the good info. I had a feeling I needed to pick up the RPM a little more when my bike would chug a few times when it was around 2000 rpm. Not like a car I'm finding out. I think in the city I'll keep the rpm around 3500 to 4500 and on the highway between 5500 and 6500. That should keep the Duc happy.
I did look over the handbook and it just talks about how to break it in and then after the break in period not to exceed 7000. I'm guessing the rpm should be around the same as the speed I'm at. So, 35 mph = 3500 rpm and so on. I hope...
My CTS sensor broke on the bike last week. So, I have to wait for a few weeks until that gets fixed at the shop.... Do you know if this is a common problem? It is a sensor that tells your bike to feed fuel. My bike would die at start-up with low rpm and would stall. I would have to open the cold start choke to not stall at stop. I'm just hoping this is not the beginning of list of bad things with my bike... Keeping my fingers crossed, and looking forward to getting it out on the road soon.

Relax. That sensor failure seems to be rare. Just a random fluke that all mechanical
things are prey to. My '99 M750 has 26K miles on it, and so far it's been a paragon
of reliability. Other than a failed neutral switch and an bulb here and there, it's
been as dependable as tomorrow's sunrise. I suspect your experiences will mirror
mine.

I'm sure you are right about the sensor failure. It's funny though, when I asked the guys at the shop how much everything will cost me, they tell me that they really have no idea yet, because no numbers are down. Is this common? I'm getting the sensor fixed, which they are ordering from Italy and the 600 mile check-up, plus the "Pre-Delivery Inspection." So, I can transfer the warranty into my name. If anyone knows what I should expect to pay for all this, that would help me out.
Thanks!

This thread may be a bit stale, but I'd like to comment on a couple of things. Being new to the Monster scene, I've found the RPM range to be most preferable at 3500 up to around 6K. But, unless on the highway, its sometimes hard to get out of third gear on my S4. The frustrating thing for me is having to deal with the erratic flow of traffic... sometimes not even getting out of second gear! And the popping and gurgling from my baffleless Termis (from the front rider position anyway) seems to wind up and down. If I shift up a gear, it seems only a few seconds and I'm having to downshift again. Ugh. Not downtown city traffic either - mostly suburban. Ahhh.... give me back roads.

And in case you've put 5K miles on your bike in a month(!!!), I was at the dealership here in Cincinnati yesterday, asking about the cost of the 6K service (the biggie). He told me a day's time, and around 600 bucks. So, I'll be getting that done this fall, along with a new back tire. Jeez, these things are expensive.
