Wiseco 4466M07550 High-Performance Piston Kit Bore Compression - 75.50mm 10.5 1

The Wiseco 4466M07550 is a forged 4-stroke piston kit designed for specific engine applications and built to tight tolerances for the ultimate combination of performance and strength. This kit features a 75.50mm bore size with a 10.5:1 compression ratio and represents a 2.50mm oversize configuration. Forged from aerospace-grade aluminum alloy, the forging process compresses the material's molecules, increasing density and aligning grain flow for superior resistance to impact and fatigue.

Performance Features:

• Engineered, forged, and machined in the USA
• Crafted from aerospace-grade forged aluminum for exceptional strength and lightweight durability
• High silicon, low expansion aluminum alloy for superior heat transfer and reduced weight
• Diamond-turned CNC finish ensures precise tolerances with no size variation
• Innovative forging design and piston skirt provide maximum horsepower and torque
• Compatible with all modern cylinder bore compositions including cast iron, chrome, Nikasil, and boron composite

Complete Kit Includes:

• High-quality piston rings
• Wrist pin
• Circlips (piston pin retainers)

Proven at every level of riding, Wiseco 4-stroke pistons deliver the power and reliability demanded by both high-performance racers and recreational enthusiasts. This piston kit is ideal for engine rebuilds requiring oversize pistons to restore compression and performance.
