Wiseco K0113X25 Piston Kit Oversize - 0.25mm

The Wiseco K0113X25 is a high-performance piston kit engineered for powersports and motorsport applications. Wiseco pistons are forged from aerospace-grade aluminum alloy using a proprietary cold-forging process, resulting in a stronger, lighter piston compared to OEM cast alternatives. The X25 designation indicates a +0.25mm oversize bore, making this kit ideal for engine rebuilds requiring a slight bore hone to restore proper clearances.

Key Features:

• Forged aluminum construction for superior strength-to-weight ratio over cast pistons
• +0.25mm oversize (X25) for use with bored or worn cylinders
• Precision CNC-machined to exacting tolerances for optimal fit and reduced friction
• High-silicon aluminum alloy for excellent thermal expansion control
• Includes piston, wrist pin, circlips, and piston rings as a complete kit
• Designed to meet or exceed OEM performance and durability standards

Wiseco is a trusted name in performance piston manufacturing with decades of experience supplying top motorsport and powersports competitors. The K0113X25 kit simplifies engine rebuilds by providing all necessary piston assembly components in a single package.
