It contains all the technical info about the bikes and teams and riders for MotoGP, Moto2 and Moto3. Full stats of each MotoGP race, qualifying and practice, graphic of rider position for each lap and race classification. Plus most important the rider and manufacturer/team standings.
The coverage of WSB and each event is acceptable, as are the BSB, TT and road racing, bearing in mind keeping the annual to a sensible size.
The photos are excellent, with plenty of different race and pit views.
I have bought Motocourse every year from 1979-80 and read it from cover to cover.
