Product Details

The Wiseco PK1714 is a complete top end piston kit designed for 1988–1992 Yamaha YZ80 two-stroke motocross bikes. This kit features a 50mm (569M) overbore piston, making it the ideal solution for rebuilding or overboring a worn top end back to like-new performance.

Wiseco forged pistons are manufactured using a high-strength aluminum alloy forging process, delivering superior strength, lighter weight, and better heat dissipation compared to cast pistons. The result is improved durability and consistent power output — critical for the high-revving demands of a two-stroke motocross engine.

Kit Includes:

  • Forged aluminum piston (50mm / 569M bore)
  • Piston rings
  • Wrist pin (piston pin)
  • Circlips (wrist pin retaining clips)
  • Top end gasket set

Key Features:

  • Forged construction for maximum strength and durability
  • Precision CNC machined to tight tolerances for optimal ring seal
  • Complete kit includes all necessary hardware for a full top end rebuild
  • OEM replacement quality or better — no additional parts required
  • Designed specifically for 1988–1992 Yamaha YZ80 two-stroke engines

Whether you're performing a routine top end rebuild or restoring an overbored cylinder, the Wiseco PK1714 provides everything needed to get your YZ80 back on the track with confidence. Wiseco is a trusted name in American-made performance pistons for motocross, off-road, and powersports applications.

Good

i will let you know when i receive. i like the feel of the cream but do not care for the smell.

Thank you

Great shopping experience except I did not receive the discount promised by the web site because I could not find any place to enter the coupon code during check out. Otherwise I'm glad to find your site. One other small issue. I did not receive any tracking information when the order shipped and it arrived a couple of days later then expected so that caused a bit of worry. A tracking number would have been great to have.

GOOD SO FAR

Smooth transactions

thanks it was simple

Accurate pictures and descriptions would be helpful. My vehicle is a boat which was not available from the selection.

Timing gearset arrived in under 48 hrs! Gears look well made. Can't wait to get them on my car. Thanks for the great service!

easy

I ordered this Weathertech cargo liner (order#: 8049) on a Tuesday and received it by Saturday. Speedy delivery and absolutely love this product. It is a perfect fit and still easy to get to the storage compartment of my Rav4.
