Imagine a 996 with 14/48 gearing!

I'm just about to change to 14/39 ...

Actually saw a bloke running 15 48 or 14 48.

Lasted half a track day before wrecking himself and the bike.

14/48

I think you would really struggle to keep the front wheel on the deck!

My 748s has standard sprockets. Under some serious throttle in 3rd it doesnt even raise an eye brow.

Me mates 995i Triumph has a reduced front sprocket and lifts up like a C90 with nitrous.

Does anyone recomend changing the front sprocket on me Duke ?

Common consensus is that as the 748 comes standard with a 14th front that if you want to lower the gearing you should go up on the rear.

Is it common consensus that the rear mod is the way to go ?

Or should I just leave it standard ?

It's up to you really. If you're happy to sacrifice a little top end for more acceleration then go for it. For a 748 I would add teeth to the rear sprocket, go up 2 or 3 and you'll notice the difference I think. If you want a big difference add more but there are implications on your ride height so if you do it yourself make sure you measure your ride height before you start goofing around and set it back to that when you're done.

My 996 standard is 15/36 - I went to 14/36 and now I'm going to 14/39 :devil:

I don't use the top end anywhere so I'd rather have the seat of the pants acceleration.

Rattler how did a 16 tooth front lengthen the wheelbase?? To me thats a larger than std sprocket which would shorten the length of the chain ....unless you fitted a longer chain!!?

I think 15/38 is a nice compromise on the 99*s

Sorry, my fault - too much sauce!!! I went one down on the front!! a 14t I think!!!
