Folks, I know this issue has been addressed, but I'm having trouble finding a good-fitting answer. If I want to change the gearing on my 2001 M900i.e. (for the normal desired effects), which is the best way to do it? Change the front, change the back, or a combination of the two? I am a commuter (including superslab miles) but also enjoy twisties. Losing some top-end speed doesn't bother me. That said, what size chain would I need to fit that particular set-up? Thanks.

I went up two teeth in the rear on my '00 900ie.. makes a noticeable difference. I would go with that first, and it that's not enough you could go down 1 tooth in the front.

This subject has been covered many, many times. Here's the summary: Drop one tooth in front or add two to the rear. You'll be happy with the result. You shouldn't need a new chain for either change.

I bought a 14-tooth front from the dealer a year or two ago for around $20.00. It's worth that small investment just to find out if you like the difference.

going "up 2 teeth" would (forgive me) put me at 40, right?

Sorry to rehash, Scott, but I didn't know if there was a huge variance between particular models/years. Is there some issue with seeking clarification from the more experienced, older riders, even if has been covered elsewhere before?

The reason I gave you an actual answer rather than a "go do a search on sprockets" answer is because it's worth making it easy for the newer members to get the information they need. There should be information on gearing changes in the FAQ, but it doesn't say much more than my summary, above.

The 1997 M900 and several others years of M900 had a 39-tooth rear sprocket. Some of the later M900's had 38-tooth sprockets because they had a little more power to pull with. A 15/41 sprocket set on my 1997 was almost perfect gearing and the 14/39 that I switched to when I had to replace the chain was probably more perfect. You want to lower your gearing by 5-7% from stock.

I'm happy to continue to answer questions that have been asked before, just don't expect as much detail as the first few times the question was answered.

I'll give it a whirl (no pun intended). I appreciate your help and realize that for you guys who have been around since the beginning, it can get repetitive... and it might also get repetitive... but you are right: it does help this newbie tremendously. Now, if only I can get her to crank in -4 degree weather...

I have a 14 front sprocket and a 39 rear sprocket coming my way soon! The original gearing on my 98 M900 is just terrible.......i guess i can pull 220 km/h on it if it had the power. But thats not interesting for a Monster with removed fairing ;D ;D Love to try the new gearing!!!!!

I ordered a 40T aluminum rear sprocket from sprocketspecialists yesterday. Looking forward to trying it out. Got crazy with the plastic and ordered some cycle cat frame sliders from Chris, too... I guess if it's too cold to ride every day, at least I can wrench!

SnapperD,
just some figures for your information.

I have a 14/39 config & that tops out at 8,500rpm in 6th at 200kph.

I like it that way!

I see nothing wrong with revisiting some topics like this, in fact I think it's good. Keeps the knowledge fresh instead of forgotten!
