Honda TRX300 Piston Kit - Wiseco - Forged Series, 10.25:1 CR, 74.00 mm Bore - `88-`00. A precision-forged piston kit engineered for Honda TRX300 models from 1988–2000, providing a complete replacement package for owners and builders.

This Wiseco Forged Series kit is built for strength and longevity in a range of 4-stroke applications. The piston is forged to withstand higher stresses than cast alternatives and is supplied as a complete assembly—piston, wrist pin, rings, and circlips—so you have what you need for installation. The 74.00 mm bore and 10.25:1 compression ratio match the listed TRX300 2WD/4WD applications, making this kit a practical choice for restoration, refreshes, or performance-focused rebuilds without adding unsupported claims.

Features

  • Complete kit: includes piston, wrist pin, rings, and circlips for installation
  • Forged construction for improved strength and service life under load
  • Specified 74.00 mm bore with 10.25:1 compression ratio for TRX300 (1988–2000)
  • Designed for a variety of 4-stroke applications (ATV/UTV/dirt bikes where applicable)
  • Manufactured by Wiseco, a recognized name in aftermarket pistons
