racing motorcycles on a track
black asphalt motorcycle track
dead grass next to the track
The motorcycles are turning a corner
The motorcycles are in a race
The motorcyclists are competing fiercely
The motorcyclists are all wearing helmets
The motorcycles are on a racetrack
The motorcycles are moving fast
Motorcycle racers entertaining a crowd
four motorcycles in a race
an asphalt race track
the dead grass 
a motorcycle race
motorcyclists riding motorcycles in a race making turns on the track
