Replacing front sprocket for better low end powergreenspun.com : LUSENET : MV Agusta F4 : One Thread
Hi all, anyone tried or have any info on replacing the front sprocket to a smaller 13 tooth to improve the low end power on a standard F4? Thanks.

Fiorello, Have you changed your rear sprocket? I went from the stock 40 tooth to a 42. You can also get a 43. I have done other mods too and power comes on at 6500 rpm instead of the 7500 rpm I observed when stock.

i havent changed the rear, i have a 42 tooth rear sprocket. i would think going from 42 to 43 rear shouldnt make as much differance as changing front from a 14 to a 13 sprocket.

Hi, Is'nt the stock front sprocket 15T on the F4?

i will have a look when i next get a chance at the front sprocket size. they may be different sizes on the Evo' 2 & 3. i say this because Casoli have a 13tooth sprocket on suitible for Evo 1.

evo02/03, front sprocket 15 teeth. earlier bikes, front sprocket 14 teeth. Roland

thanks for the responses, i have looked at my front sprocket & it is 14 teeth. my rear is actually 41 not 42 teeth. Not sure if i am correct, but changing the front from 14 to 13 teeth is equivelent to increaseing the rear sprocket by 2.9 teeth (41 divided by 14). if this is the case, then changing the front only costs AUD $80, opposed to replacing the rear which costs a lot more & maybe needing a longer chain.
