bigger front sprocket - Yamaha FZ6 Forums - International FZ6 Motorcycle Community Forum

Tapped Out · 08-22-2008, 04:02 PM

I have been thinking about switching my front spocket to a tooth bigger. from a stock 15 to a 16 I believe... I was hoping to get lower RPM at higher cruising speeds and perhaps increase gas millage a bit. Has anyone tried this or know of any major drawbacks?

I'll be interested to hear what people think as I've been thinking the same thing

Just to reply I have no idea what it would do if you changed the sprocket. Sry.

2007 fz6's come with a 16 tooth in the front (mine did at least) so you would convert to 17. As for if saves gas and such, i'm not too sure. I believe you would have to change your gearing as it might feel thqat you are trying to take off in second gear. (correct me if i am wrong). I am interest in knowing myself.

yea you probably meant from 16 to 17 cause not only the 07's but as far as i know all the FZ6's have 16T counter sprocket...

it made a big difference when i went -1 to 15T,,,,i would say 17T should be helping a lot at highway speeds,,,if you dont have any problems accelerating not as quicker as stock,it would be great for highway riding thats for sure...

hmm, well, maybe I'll just have to try it and let everyone know what happens...

Can anyone recommend a good place to buy Sprockets and chains? I have heard that its a good idea to change them all together as the chain and both sprockets tend to wear together.

TourGuide runs a 17T up front and swears by it....he does some highway and a lot of twisty mountain road by himself and with his wife.

Unless your current set is showing noticeable signs of wear, I'd just swap the front sprocket for ~$30 and be done with it. If your entire set is well on it's way to being replaced, then yes, perhaps a full replacement is in order.

One other thing, your speedo will probably be MORE accurate than stock but your ODO will be off.

Just do a google search, they are for sale all over. From what I understand, the pre07 countershaft nut was 32mm and the post06 nut is 30mm...I'm not sure if they take the same size sprocket or not so pay attention when you're buying.

yeah i've run the 17 for @ 10,000 miles. i prefer it cause it drops you back @ 300 rpm ( i think ). and yeah it makes the speedo closer to correct. i just ordered mine from a local dealer. the stocker has the rubber insert which makes it a little quiter. the replacement will be solid and you will hear a little more chain whine. you can run the cahin a little looser than normal and that helps. and no it don't make me any slower!

I put a bigger sprocket on my dual sport...
It is a lot smoother and you aren't pulling so many RPMs at cruising speed.

Different bike but will cause same effect on gearing.
Went down a tooth on the fz6 to have better take-off.
