Vertex Piston Kit CAST REPLICA HON CR 250R 05-07 STD 66.35mm

Manufactured in Italy, Vertex pistons is the premier choice of aftermarket replacement and performance pistons for dirt bikes, ATVs, and UTVs. Using both cast and forged manufacturing processes enables Vertex to supply the highest quality pistons. The silicon content in Vertex pistons is crucial to the quality of the piston. Silicon is critical in decreasing thermal expansion which, when an engine reaches normal operating temperatures, can change the geometry of the piston. Controlling this expansion means that a Vertex piston can be run at tighter tolerances for more power, less noise and a longer lifespan of the piston. Plus, the silicon content decreases wear on the piston skirt which also aids in the life of the piston. In addition to the silicon, each Vertex piston utilises a unique Molybdenum Disulphide (MOS2) coating which aids in the break-in process and reduces overall wear.
