06 Speed triple countershaft

[jamboa2003]

What is the tooth count of the stock countershaft sprocket on a 06 Speed Triple? I could not find it in the owners manual and tried a search with out any success.
Thanks.

Everything you need to know

Stock gearing is 18/42.

If you are looking for better acceleration, going up in size on the rear is preferred by many as it gives the plastic swingarm rubbing stripe a bit easier life than dropping teeth on the front. Also changing rear sprocket is a bit less hassle as you can easily just unbolt the old and replace with new. No need for even a rear stand for this.

How many teeth up can you go on the rear with out getting a new chain?

44 will fit for sure.
45 on a new unstretched chain, most likely won't.

I have several bikes and just as soon have the Speedy geared down as I do little Interstate riding. What is the best sprocket sizes people have tried on the 1050 S3? I was thinking 17/45? Will this be geared too low for top gear?
