Product Details

The Wiseco PK1819 is a Pro-Lite forged 2-stroke top end piston kit featuring an 88.00mm bore (546M) designed for the Yamaha YZ490 and WR500. This complete kit supplies everything needed for a top end rebuild or overbore service, making it a convenient one-stop solution for restoring engine performance.

Pro-Lite Piston Technology:

  • Forged construction — engineered, forged, and machined in the USA in Mentor, OH for superior strength and consistency
  • CNC machined for optimal cam shape and profile, maximizing horsepower output and service life
  • Dedicated forging design for strength-to-weight optimization
  • Extra lightening operations for enhanced throttle response
  • Horizontal slot-pin oiling reduces friction and provides scuff resistance
  • Pressure seal groove for maximum ring seal

Kit Includes:

  • 1 × Wiseco Pro-Lite forged piston (88.00mm bore)
  • Piston ring set
  • Wrist pin
  • Wrist pin circlips (2)
  • Top end gasket set

The Wiseco PK1819 is a proven choice trusted by top race teams across Supercross, Motocross, GNCC, WORCS, and more. Whether refreshing a trail bike or rebuilding a competition engine, the Pro-Lite series delivers reliable performance and lasting durability in a complete, easy-to-install package.

It would be nice if you linked the driver side part at the bottom of the page for the passenger side part. This would have made it really easy to switch back and forth between the two. It would also eliminate a search within your site. Google brought up your passenger side mirror and I needed the driver side one.

Fast and convenient with Amazon pay! Thanks!
