VERTEX PISTON-PRO REPLICA fits for Yamaha 4T YZF 250 08-12

Four-stroke engines have much higher cylinder pressures when compared to twostrokes
and are generally manufactured from forgings. To handle the internal
pressures of a four-stroke engine, Vertex’s four-stroke pistons are forged
from the highest quality 2618 aluminum alloy for superior strength and durability.
Vertex uses unique piston profiles and compression ratios,
offered in A, B, C and D sizes, to maximize power and performance while
reducing blow-by and oil consumption.
