Product Details

The Wiseco K132 is a complete forged piston kit designed for top-end rebuilds and overbore applications on the Yamaha RD350 and RD400. With a 65.5mm bore diameter (1.5mm oversize) and Wiseco part codes 2579CD / 393M, this kit delivers everything needed for a full top-end rebuild in a single package.

Wiseco Forged Advantage:

  • Forged from aerospace-grade aluminum — the forging process compresses molecular density and aligns grain flow for superior resistance to impact and fatigue
  • Engineered, forged, and machined in the USA in Mentor, Ohio
  • Dedicated forgings provide an optimized strength-to-weight ratio for 2-stroke powersports engines
  • Improved tensile strength extends service life versus cast alternatives
  • Each piston is designed with precise installed clearance for maximum power, minimal wear, and optimal cylinder seal at operating temperature

Kit Includes:

  • Forged piston(s) — 65.5mm bore (1.5mm oversize)
  • Piston ring set (Wiseco 2579CD)
  • Wrist pin(s)
  • Circlips
  • Top-end gasket set

Note: Wiseco ring types are not interchangeable between piston series (e.g., CD rings fit only compatible Wiseco pistons). Cylinder boring is required to use this oversize piston kit. UPC: 193564155221.

So far so good!!!!

Quick and easy. Good prices, too

Best price on line. I did call customer service for a question and was on hold for 30 minutes. Be prepared to wait.

Great prices!

quick and easy

On drivers side, tube was contacting the body trim (2014 Toyota Access cab) after torqueing the bolts. Gap between body and tube was not uniform. Added small shim at center mount and approximately 1/4 inch shim in the front to achieve clearance and uniform gap. Longer bolt required. Right side installed perfect with no issues.

Great price on quality product and fast shipping

So far so good.

I found exactly what I needed and it went very smoothly.

Good web store front. Makes Parts Geek look like the trainwreck it is.

I purchased an Airaid throttle body spacer, they has they cheapest price on the web, no one else could even compare to the prices here at Autoplicity, I will definitely order from in the future!

Finally I found the part I have searched all over for. Thank you autoplicity for having such a specialized part. Great customer service too. Very easy to use web site as well.
