Front cog
 

To change or not to change, that is the question.
If yes, to what and from where do I buy,

I believe that Amsterdam have lots of spare cogs from thieir windmills.:lol:

14 tooth?

Will this make the speedo inaccurate?

no speedo runs off of the front wheel...............

I would go up on the rear sprocket rather than down on the front....... less stress on the chain with a more powerful bike than a 748 that has 14 as std...........and you could have a bling sprocket carrier.......

But if you go up on the rear you will shorten the wheelbase , i run a 14 tooth on my 998bp althought the S is up a few brake hp

You could spend the money and put a Renthal carrier on the rear change the chain & sprockets at the same time that way you can keep the wheelbase std or go longer

I have and would allways go for a longer chain to keep the eccentric at the bottom and even 5 o clock as you look at it sprocket side!

besides if you fitting new sprockets you really out to fit a new chain anyway!

why will there be more stress on the cog ?

let me make you think a little... before I answer this one

the diameter of the cog is smaller ?
It is subjected to the same power ?
The chain will transmit more or less power ?

Rather than power think pressure, clearly for a given chain size a smaller number of teeth mean a smaller diameter, means a larger pressure on each tooth! IMHO:o
