How many pistons do I need for my Yamaha YFZ450?

The Yamaha YFZ450 engine uses a single cylinder. Therefore, you will need one piston for a standard rebuild. This part is sold individually.

What is the difference between a forged and a cast piston?

Forged pistons are made by heating aluminum and hammering it into shape, which creates a stronger and more durable grain structure. Cast pistons are made by pouring molten aluminum into a mold. Forged pistons are generally preferred for high-performance or heavy-duty applications due to their superior strength.

Does this piston come with rings or a pin?

This JE Pistons part number 247952S is for the piston only. It does not include piston rings or a wrist pin. These components are typically sold separately and should be sourced to match the piston's specifications.
