Final answer:
Motorcycles under 600cc have a smaller U-turn area than motorcycles 600cc and over.
Step-by-step explanation:
In general, motorcycles with engines under 600cc have a smaller U-turn area compared to motorcycles with engines of 600cc and over. This is because smaller motorcycles are typically lighter and more maneuverable, allowing them to make tighter turns. On the other hand, larger motorcycles may have a wider turning radius due to their increased weight and size.
