Sprocket sizes

[Gubb]

It's time to get my Chain and Sprockets done. I've just hit 30,000Km, and run out of adjustment. I want to change the Sprocket sizes. From what (little) I understand, dropping 1 tooth on the front, or adding 2-3 on the rear Sprocket provides better acceleration, and the cost of top-end speed. Is that right?

Question is, is it generally advisable to alter the front, or rear sprocket, or does it make fuck-all difference?

Fortunately, I can re-program the ECU to correct the Speedo error at Home, so I don't need to worry about a false readout, or a speedo healer.

Thanks guys.

Sounds like a good idea. A 250ish kph potential top speed is a waste of time here in NZ.

They do kits with the right ratio for your bike. I heard of them on the Rat site. You might want to check the results others have had before taking the plunge.

TuneECU is an amazing piece of freeware :yes:

www.gearingcommander.com is your friend here!

worst thing about changing gearing is higher cruise rpm I reckon, if you got a bit of room for movement there then go for it :yes:

Wicked site. Thanks bogan!

1 tooth difference on the front has about the same effect as 3 difference at the back, but obviously 1 tooth at the front is easier to accomodate within the standard chain and cheaper as well. Going too small (ie like 13 - 14) on the front causes more chain wear.
