Forging the aluminum makes it denser and stronger than cast pistons, allowing for higher compression ratios and improved durability under demanding conditions. This specific piston is designed to fit right into the Yamaha YZF R3 engine, making it a solid option if you're rebuilding or upgrading your top end.
