The top version for racing will have to come in under €40000 which is about £34500 which is about what the panigale R costs so a more cooking version should be a lot less! It won't be cheap but won't be to much more than the base panigale now I reckon
The base Panigale 2017 "just" £ 17,995. Let's wait and see, but I am sure you won't get the new V4 for that price at all.
