Product Details

The Wiseco 4045M08800 is a high-performance oversize piston designed for dirt bike applications. This precision-engineered piston features a 1.00mm oversize bore dimension (88.00mm), making it ideal for rebuilding worn cylinders or increasing displacement in compatible dirt bike engines.

Complete Kit Includes:

  • High-silicon aluminum alloy piston with advanced skirt coating
  • Premium piston rings pre-gapped for optimal seal
  • Wrist pin (gudgeon pin)
  • Circlips for secure wrist pin retention

Key Features:

  • CNC-machined from forged aluminum blanks for superior strength
  • ArmorGlide skirt coating reduces friction and wear
  • Optimized ring groove design for improved ring seal
  • Controlled thermal expansion for reliable performance
  • Race-proven design used by professional riders

Wiseco pistons are manufactured in the USA to exacting tolerances and are designed to handle the extreme demands of high-performance dirt bike engines. This 4-stroke piston requires proper clearancing and professional installation. Note that only genuine Wiseco replacement ring sets should be used for service.
