Ducati Monster Forum

My chain is toasted on my 2009 m1100, and it's eaten my rear sprocket as it stretched.  Time to replace it all.

I'm thinking about dropping to the 14t in the front and will stick with a 525 chain.  Seems like it should be easy to find a rear sprocket for cheap, but none of them seem to fit a m1100 unless I get into a costly quick change setup.  Can someone point me to a 39t 525 sprocket in steel that will fit?

While I'm at it, is it worth going up to a 40 or 41 in the rear?

Keep a 15t front, go bigger on rear.

SuperSprox Stealth is about the best option.

+1.

I switched to a 14t in front and it accelerated the wear on my chain - I think it has to do with the increased angle as it wrapped around the sprocket. I used to get 20K miles on my big Kawasakis, won't get more than 12K on the Monster.

SuperSprox is also a pretty good recommendation.

I've used the SuperSprox on two other bikes and been happy with them but this time went with an AFAM from one of our friendly site sponsors just because it looked to be easier to clean; solid black color vs anodized center.

Thanks for the recs.  if I go up in the back (say a 43 or 44) will a new chain reach?

At risk of sounding like a cheapskate, isn't 300 a bit much for a rear sprocket? 

You usually replace both sprockets and chain . . .
