Thumbs up 14T Front Sprocket Recommended !

Finally got the bike gearing as it should be .
The 14T sprocket is perfect. makes the bike accelerate sharper & much smoother through every gear & with a lot less vibration all-round.. Riding in & around the City is now enjoyable, no more lumpy chugging vibes at slow speeds .. from 25 mph in 3rd gear it will accelerate without struggling or having to change down into 2nd.
all-in-all much smoother in every gear & on the open road it accelerates like a rocket.
also there is no electronics adjustment to be done...DQS, ABS, TC, Speedo' all work the same,
I found the QS actually works much better....Oh nearly forgot, a less vibes on the mirrors also.

Have you tested it at a constant 70mph, (normal A road/motorway speeds).

Colin...I did 70 miles today.. not only did I test it at a steady 70 & 80 mph.
I put it through its paces & took it up to 105 mph & the happened in a very few seconds.. unbelievable...

The 105 was obviously on some private land

I considered doing this as it was a good mod on the 848 that I had last year. I decided against it on the Supersport as it would up the revs on the Autoroutes. I tend to keep up 150 kmh heading north when I go to the UK, for 800 kms, so that would use more fuel and make the bike more buzzy.
If I was just using it as a town or short run bike then I would do it.

I think in 6th gear you would find it very comfortable at 90 mph on the motorway...
After todays 70 mile thrashing it was showing 54 mpg.

I find it very comfortable as it is, would be nice with a 16 tooth front sprocket at that speed. You would then get 58 mpg!

You need to fit a derailleur to the bike, then you can have the best of both worlds

Fred each to their own...mpg isn't an issue at all for me...
I find the bike much much better all-round with the 14T..
