i run a 14 / 37, still overtakes a guy on his R1 flat out in top, and pulls away sweetly.

there are some who say not to go with the smaller front as it turns the cahn tighter, but ive never had any problems with it. chain life seems fine etc

So if I go a tooth smaller on the front to 14T and keep the 38T rear I should see a difference... yeah ?

Oh yes !!!!!!!!!!!!!! Talon make a 13 front, but it runs too close to the swinging arm. 14 will be fine

Brill final question, how much for Renthal 14T front sprocket

[bill955]

£17.32+vat

Thanks for that. All the best to you all.

There's a "sweet spot" - around 4,600 RPM @120Km/hr in 6th gear for liter displacement superbikes, a little higher for 74X's. Obviously, faster tracks will require rear sprockets with fewer teeth, slower tracks more teeth (and possibly longer chains.)

I strongly recommended NOT changing the stock front sprocket or chain size for safety reasons. Just my opinion.

Shazaam!, I used this very chart that you kindly provided earlier in the year when I changed my gearing. Only problem being the listed sprockets for the 996R are incorrect. They have a 36 tooth rear as standard. Apart from that its a great bit of info.

Happy New Year!

If you do go that way let me know how it is as now I am running just a
15 front and 38 back, so curious how much of a difference it will be, if that front wheel comes up
