What size sprockets should I get?

Postby kawigreen » Mon Sep 03, 2012 8:44 pm

So I'm getting ready to replace front and rear sprockets and chain. Is there one or both I should change I know on my dirt bike change 2 larger in rear and I think one smaller on front change the whole ride. I mainly use for commuting no track time. I don't nessarasarily wanna sacrifice gas mileage but if changing could smooth out bike I'd go for it any suggestions?

Stock gearing is perfect for commuting.
Remember 6th gear is overdrive, so going too small in the back can be an issue.
15/45 highway
15/47 city
14/47 for doing wheelies

Stock is 15/46
Chain is 114 links.
I don't have a kit, but

I have 14/15/45/46 in stock
I don't stock the chain, due to people wanting different colors.
Chain is usually only 1 day out once I order it.

Im relatively new to forum and was searching for answers to avoid repeating subject. Anyway, My 09 650R is going to
the shop for air box mod, air filter replacement, PC V, slip on and block off plates. With these upgrades, what are recommendations on sprocket size. Gary posted quote up top but i believe it was for someone without mods or power commander. I'm looking to upgrade evenly with top end and torque. I do ride highway as much as back roads so im looking for a good all around size (in teeth)to complement pwr commander and other mods.

I went to 15 / 47 - and I'm REALLY happy with it.
I did that because it (mine anyway) haD a very nice smoothness at the RPMs of about 73 MPH.
73 is a faster than I want for my 'normal highway' speed.
Now I'm in the sweet spot at 68-70. And I have ridden at that speed for hours at a time.
And yes, it does wheelie just a little better, which I'm totally okay with :)
