Sup y'all? I've noticed my chain is wearing out a bit, its stalling my Duc alot now.
I'm looking into a chain and probably replace the sprockets, I'd like to regear those to get a bit more speed and better mpg. but idk how many teeth my factory sprockets have.
if anyone knows and would like to share thatll be great.

Define what you mean by a little more speed? Top speed or acceleration? If you're going for acceleration you won't get better mpg because your RPMs will be higher.

top speed, ive heard some people do sprocket conversions on their shadows from 44T to 40T, gets better mpg and highway cruising is smoother.
of course thats just to explain what im talking abt, Monster and Shadows are two very different bikes.
Before doing anything, if you are not the original owner, confirm what sprockets are on the bike. Most folk change gearing, usually in the opposite direction you are going since the more common opinion is Ducatis are geared too high out of the factory.
Increase top speed? Math says so, but not aerodynamics. If a vehicle does not reach the torque peak in top gear you may find top speed the same or diminished since you will not have the power to overcome aerodynamic drag. No guarantee of better fuel economy either unless you maintain ridiculously high speeds. You will find taking off and low speed riding hampered though.
Stock gearing is 15 front/41 rear.

Physics, not just a good idea.
As for MPG - look at your right hand. That will do a lot more to your average MPG than a few teeth on a sprocket.
last, if you're changing the chain, change the sprockets as well. Don't cop out. If you don't you'll see premature wear on the chain and what's left of the sprox will wear faster.

You sure? My '03 M1000 is 15/39. I'm not the original owner but the rear sprocket part number is Z39 with the Ducati logo on it. So I assume it's factory. Then again you're probably referring to his particular machine's stock gearing.
Could always go with a quick change setup. It may cost a bit to find the 'sweet spot'. But you could always sell off the near new gears you don't use for near what you pay.
