Product Details

The Wiseco PK1045 is a complete forged piston kit designed for 1988–2000 Honda TRX300 ATVs, featuring a 75.5mm bore diameter (oversize designation 4629M). Wiseco's top-end kits are engineered to deliver a reliable, high-quality rebuild solution for both trail riders and performance enthusiasts.

Each kit is built around a forged high-silicon aluminum alloy piston, which provides superior strength, reduced weight, and improved heat dissipation compared to cast alternatives. The forging process results in a denser grain structure that withstands the demands of hard trail riding and extended use.

Kit Includes:

  • Forged high-silicon aluminum alloy piston
  • Piston rings
  • Wrist pin (piston pin)
  • Circlips (retaining clips)
  • Top-end gasket set

Key Features:

  • 75.5mm bore diameter — designed for overbored or rebuilt cylinders
  • Forged construction for maximum strength and long-term dependability
  • Complete kit contains all components needed for a full top-end rebuild
  • Available for both trail and racing applications
  • Wiseco's broad fitment range covers a wide variety of popular ATV models and years

Note: Cylinder sleeve must be purchased separately if required. This kit is intended for use with a properly machined or re-sleeved cylinder bored to 75.5mm.

Excellent service. I called in Monday for a hard to find item which I had ordered from several other online shops who despite saying were In Stock online were not actually in stock at all and the orders were canceled after waiting a week to find out. They had the item in stock as listed on their website and shipped the next day. The price was the cheapest of anyone who actually had the item in stock by a substantial amount.

Thanks for the great service, best prices, and fast shipping!!!
