Wiseco 693M05400 Pro-Lite 2-Stroke Piston Kit 54mm Standard Bore

The Wiseco 693M05400 is a complete Pro-Lite piston kit designed for 2-stroke dirt bike applications with a 54mm standard bore size. Wiseco is unique among aftermarket piston manufacturers in the United States because it is the only brand that produces pistons strictly using the forging process, starting with aerospace-grade aluminum that compresses the material's molecules, increasing density and aligning grain flow for superior strength and fatigue resistance.

Key Features:

• Pro-Lite design is CNC-machined for optimal cam shape and profile to maximize horsepower and service life
• Forged from high-silicon, low-expansion aluminum alloy offering superior strength, reduced weight, improved heat transfer, and longer life
• Diamond-turned finish from CNC computer-controlled turning centers guarantees a perfect finish with no size variation
• Compatible with all modern cylinder bore compositions including cast iron, chrome, Nikasil, and boron composite
• Manufactured in the USA using race-proven designs

What's Included:

• Forged piston, piston rings, wrist pin, and circlips

This Wiseco piston kit features an optimized design to improve engine efficiency and maximize torque and throttle response. Wiseco engineers utilize the latest 3D design techniques and finite element modeling software to ensure each design provides the highest strength and lightest weight for each application. Ideal for both racing and recreational riding applications where performance and reliability are essential.
