Front sprocket sizes

[Davew]

Sorting a few little jobs with my new 2001 600 fzs and wondering about the front sprocket sizes. Did they change the size after the early models to an extra tooth? I'd rather have a smooth to a super revvy feel and wondered what the general consensus is on here? I'm presuming mine has the standard front sprocket but will check.

You could go up one tooth on the front but if you didn't want a revy bike you shouldn't have bought one with an inline four engine!

[fazersharp]

can you see these to count from an origional "98"

[limax2]

The standard sprocket sizes on the FZS600 have always been 15 front and 48 rear.
You may be able to go up one tooth on front without lengthening the chain, but I'm not sure.

Cool. Not got a problem with the inline 4, I thought I read somewhere that they'd changed the sprockets or ratios on later bikes. Just good to get other opinions.

Went up 1 tooth on my 98. No need to lengthen chain. Spindle moves approx' 2 marks towards the sharp end.1 large mark.

What did it ride like moving up a tooth?

I have gone two up on the front and two down on the rear on my w reg fazer 600, made a great difference. Still pretty quick pulling off. Now at 70mph its revving at just about 4750 rpm. Used to get about 220  to 240 miles per tank. So will see how much differce the change makes if any.

Going up one was far better. Don't know about 2 up may try that soon

I'm thinking of doing the same on our 03 Fazer, but, out of interest, how many teeth on each sprocket now - is that 17 on the front ?


And how many on the rear ?

He dont want to accelerate he just wants to go a million mlies on a tank

That would now be 17 front and 46 rear.  Standard is 15 front and 48 rear.
For interest, going up one on the front gives approx. the same effect as going down three on the rear. Going down too much on the rear would cause the chain to rub more on the slider on top of the swinging arm.
If changing the front sprocket you may as well fit the thicker (12mm) sprocket nut at the same time if not already done so.

Another one here for 2 up on the front and 2 down on the back.


And I wouldn't change it if you paid me! Bike is still RAPID, and with that engine thats no surprise. It's more than man enough to deal with the change.


As I've said in other posts, the gearing difference is exponentially applied. So in first gear the difference is negligible. But in top, around 1000 rpm less than standard. Makes the bike SO much more comfortable on the long rides.


And I've never struggled to keep up! In fact some plonker on an SV-650 tried to race just yesterday, he's still spitting out my dust  :rollin . Never ceases to surprise folks how surprisingly capable these FZS's are!

I put a 45 tooth rear sprocket on mine once.


Made a measurable difference.


I've still got the sprocket, it's done around 9000 miles (ish), and it's still in good condition.  You will have to shorten your chain though.


If you want to try it, you can have it, but you'll have to collect it.

Without trying to be disrespectful mate, have you ridden many other big bikes?

I can confirm that on a recent FOC ride he was indeed able to keep up, unless he did it after the ride out
