KTM 525 SX 2003-2006 Vertex 12.0:1 HI Comp Forged 94.96mm Piston Kit

VERTEX HIGH PERFORMANCE MOTORCYCLE PISTON KIT

As the OE supplier of two-stroke pistons to KTM, Vertex pistons has an outstanding reputation for quality and performance.

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 utilizes a unique Molybdenum Disulphide (MOS2) coating which aids in the break-in process and reduces overall wear.

KIT INCLUDES

• Piston
• Rings
• Pin & clips

FEATURES:

• Exact fit A, B, or C pistons match your cylinder bore perfectly to maximize power and performance while reducing blow-by and oil consumption
• 2-stroke pistons have an 18% silicon content which decreases wear and thermal expansion, allowing for tighter running tolerances for more power, less noise, and longer lifespan
• High-tech Molybdenum Disulphide (MOS2) skirt coating for reduced wear and improved break-in
• 4-stroke pistons are forged from either 2618 or 3032 alloys for superior strength and durabiltiy
• Cast and Forged Replica pistons are OE replacements with stock OE compression ratios
• Cast and Forged Race pistons are unique with only one compression ring
• Forged Hi-Comp pistons increase compression and power over Replica pistons
• Forged GP Racer's Choice pistons have T-box forgings, unique dome profiles, surface treatments, and increased compression ratios to produce more power, strength, and durability
• Big Bore pistons increase displacement and power while maintaining stock compression ratios

PLEASE NOTE: 

• Ensure you have measured and selected the correct size piston.
• Refer to the item title for specific piston type, size, and exact model fitment.
• Images for illustration only. Correct parts will be supplied.
