PISTON KIT VERTEX YAMAHA YZ250F 19-20 76.96MM
Vertex piston kits include the piston, rings, wrist pin and circlips. The pistons are heat-treated with a T-6 hardening and tempering cycle. Also, a molybdenum disulphide skirt coating is used for reducing wear and improving the break-in phase of each piston.
Forged Pistons for 4 Stroke
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 aluminum alloy for superior strength and durability. Vertex uses unique piston profi les and compression ratios, offered in A, B, C and D sizes, to maximize power and performance while reducing blow-by and oil consumption.
better wear characteristics and prolongs piston life by decreasing wear on the piston skirt.
