Sprocket sizes?

Hi all,

I have 02 750 F4. I am thinking of dropping one tooth on the front sprocket. From a 14 to a 13. Are there any problems with chain clearance, and can I still use the same 520 chain. Also anybody know if the gearing becomes to short. I am looking for the best of both worlds. Road riding and track.

i think most people just deal with the rear with a quick change carrier. that would be the most flexible option.

If you have an 02 it is a 15T stock. Move to 15/43. 13 is WAY too tight in my opinion.

I am just about to get my Brutale to the local garage because the petrol pump has packed up. The garage said that they were getting a few through now? Anyway at the same time I am getting the cat removed and he had recommended 2 teeth off the back sprocket as there will be more torque and this will help me to use it (i.e. lower revs).

Does anyone have ano other suggestions to be done at the same time.

2 teeth off the back sprocket? Will that not make the acceleration less?

Hi James,

So 2 teeth up on the back sprocket. I will check the front sprocket when I get home? If it is 15, then I agree that 13 will be to tight. How about a 14/41?

2 teeth off the back sprocket (this could get confusing with the 2 threads of 2 teeth). The man in the shop just said that the cat removal gave much better torque so 'lowering' the revs means you can use it better and not so manic especially on top and just cruising. I am not sure what difference the no cat will make anyway.

My other bike is a Cagiva with a Duc 900 engine so there is a big difference in revs when I swap from bike to bike. and tends to make me reach for another gear when just cruising.

I am not a fan of 14 either but that's just me Make sure you order the correct part number for the '02+ bikes. The 00 and 01 are different and all aftermarket cs sprockets that I know of are for the 00/01.

with 15/43 you won't need to add any links, if that was the concern. I also like 15/42 if your riding for that sprocket isn't so tight and technical or will involve street or track with long straights.

I would just go up in the rear as well. The chain doesn't have to bend any extra because of a smaller front sprocket. Also, a lower set of teeth on the FRONT places additional load on the shaft, as it's spinning faster due to the smaller diameter sprocket.

Go up on the rear, and get a quick release carrier.
