S1000RR - which comes with pillion seat, doesn’t have cruise control and a few other bits like sat nav and heated grips I believe.
S1000RR Sport - no pillion seat, and fully loaded with all the bells and whistles
S1000RR M package introduces a few carbon fibre parts and different wheel, so it is a little lighter
All above models are identical in terms of engine performance great for the road and better on track, but difference in price because of the extras. The M 1000RR was introduced in 2021 and that is meant to be more of everything and track focused, but the most visual difference compared to the M Package are the wings.
@T_cat I would say yes its the M Package you can see the carbon fibre parts on it which the sport does not have and it does not have wings so more than likely not the M 1000
