    so probably the fuel mapping on the SP as well as standard 17 model making it slightly more economical than the 16 maybe

    From what I researched and was told when buying the standard '17 model was the only difference between it and the '16 model was new fuel mapping to smooth out the throttle response and the quick-shifter.
    The gearing and sprockets of the SP are the same as standard.
    It is still a thirsty bugger tho, every time you open that throttle you help put an oil sheik's child through college.

    Fueling, ignition and throttle maps are different
    The throttle maps are more tame than the 2016 ones

    Therefore, a 2 tooth smaller rear spocket of the SP would account for his SP's slightly higher mpg figures.

    ^ SP Owners confirm 43t gearing same as Standard 10.

    So I NOW say no real difference in SP MPG. It's just Bob was still running his SP in and got 44 mpg part of his trip and I did get up into 43 mpg when was saving front tyre and if remembered to reset mpg calc trip comp.

    So no mpg difference, on SP, its just the normal natural variations.

    Believe SP mpg is same as 10; longer SP gearing is false misleading myth.

    Yup. No massive 2017/16 difference tho.

    There we are now...

    PS we all know UK mph is more often average in the thirties, and the thread thrust was on gearing not SP / mpg.

    At least now it is now confirmed that the SP and the standard bikes sprockets are geared the same!

    When I rode the SP I thought the throttle was miles better than my 16, much smoother and easier to ride at low throttle oppenings

    Super easy job to do, takes about 5minutes and it dropped about 150-200 rpm's so the difference is only very small.
    Took the edge off them 4th gear wheelies and made the wheelbase around 11mm longer
