How many pistons do I need to order for my KTM 520/525?

This product listing is for a single piston. You will need to determine the total number of cylinders in your KTM 520 or 525 engine and order that quantity to complete your rebuild.

What is the advantage of a forged piston over a cast piston?

Forged pistons are made by heating and hammering aluminum into shape, which aligns the grain structure of the metal. This process results in a stronger, more durable piston that can better withstand higher compression ratios and temperatures compared to cast pistons.
