What is the main function of these bearings in my RMZ250 engine?

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly with minimal friction, which is essential for efficient and reliable engine operation.

What does the '30 x 62 x 16mm' refer to?

These dimensions refer to the size of the bearing: 30mm is the inner diameter (where the crankshaft fits), 62mm is the outer diameter, and 16mm is the width of the bearing.
