I am going to change my chain and sprockets on my 999S with one of those racing kits from B&C Express. This will drop a tooth on the front and add one to the back. I would like to know who has done this mod and wonder if anyone can tell me (A) What the top end will be reduced to, And will the speedo remain to be accurate ? I know there are threads already on this but they seem to be covering 749 bikes.
Cheers
