Vertex Four-stroke Piston (Pro BB) Compr. 12,6:1 (269CC)
Vertex Four-stroke Piston (Pro BB) Compr. 12,6:1 (269CC)
Four-stroke engines have much higher cylinder pressures when compared to two-strokes 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 aluminium alloy for superior strength hand 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.
