Piston kit YAMAHA YZF 450

Woessner is a forged 4T piston made of the highest quality materials. Woessner manufactures its own forgings and ensures maximum quality control. Forged pistons have higher strength and reduce the risk of cracking, chipping or other damage under demanding conditions. Woessner pistons are surface-treated with a special friction-reducing coating. It protects against scuffing during warm-up and extends the life of the piston and cylinder. Compression ratio = 12.5:1 "Big Bore" size = 97.96mm The kit includes a piston, a ring set, a pin and locking clips. The piston size is determined according to wear - the cylinder dimension.
