Vertex Forged Pro Race Piston Kit KTM 125 SX 2001-2021
Vertex Forged Racing Pistons and KTM 125 SX 2001-2021 Piston Kit will help to improve the performance of your KTM 125 SX.
Most OEM manufacturers recommend on small-bore motocross engines need to have the piston and rings replaced every 25-30 hours to maintain peak performance and not damage the cylinder plating.
Vertex Pistons is the 2-Stroke Piston OEM supplier of two-stroke pistons to Husqvarna and KTM; they have an outstanding reputation for superior performance and stat of the art manufacturing processes. Vertex’s 125SX piston are manufactured using only premium aluminum alloys utilizing a 12-21% silicon content for reliability and long life.
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. Vertex piston utilizes a unique Molybdenum Disulphide (MOS2) coating which aids in the break-in process and reduces overall wear. The only piston choice for your KTM 125 SX is Vertex Pistons.
