Front sprocket sizes

[Millietant]

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.

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 ?


Cheers
