More acceleration ? ?

Normally to increase acceleration it's either drop a tooth on the front or increase on the rear.

Is this the cheaper option from the supercharger idea Tony???

Normally drop one from the front as Gary says. May increase the inaccuracy of the speedo tho, although I'm not sure.

Renthal are considered very good at what they do. Changing both at the same time might not be the best option. One thing at a time and then test ride is better to get you where you want to be.

Depends on where the

Depends where the speed is measured. If from the front wheel it's not affected,but if it's a sensor off the sprocket it will be.
You can get speed healers to correct the inaccuracy. I believe not the easiest thing to set up. Never used one myself. An example of one http://www.healtech-electronics.com/products/sh/
Also remember if you do increase the acceleration that the top speed will be decreased.

 

On the 2015 can you access the ECU with TuneECU?
On my 10' Speedie, I was able to adjust the speedo registered after going down one on the front and up two on the rear sprockets. I calibrated it with the sat nav speed readout.

 

Up 2 teeth on the rear would be the easiest and you probably won't need to change the chain.
As others have said you'll need to re calibrate the speedo.

 

I think you'll be OK with the speedo, the later bikes after vin 400001 use the wheel speed censor instead .

 

Doin me best Tony.
She's in and out of shops, and I'm getting neck ache watchin all the bikes go by!

Let me know what you decide to do, I may just have a play with changing the front myself.

Nice one T. Let us know how it is pal. Catch up when I'm back eh.

Bob

 

That's all good news, plan on doing the same to mine very soon.

 

Eh up T.

I think I have a 17t sprocket somewhere so I think I'll give it a go. Don't want you leaving me for dead.... At least not until the supercharger anyway...

Part of my commute is in central London and trying to feather the clutch until I reached 15-20 mph was hard work.
After the new chain n sprockets were on, riding at lower speed was a lot more controlled.
The fact that I actually have to consiously keep the front wheel down and can now out accelerate any car on the road is just a coincidence. (I always have my foot hovering over the rear brake should the front come up...too high)
Regarding top end, the book says 135mph tops on standard sprockets, I reckon the revs will redline at about 110mph now, but I honestly don't go there as I am yet to do a track day.
The accleration now is awesome though.
