Product Details

The Wiseco WK1250 is a forged replacement piston designed for the Kawasaki 1100 ZXi personal watercraft engine, machined to an 82mm bore diameter (3228KD / 809M). Built to Wiseco's exacting performance standards, this piston delivers the strength and precision needed for both high-performance and recreational applications.

Key Features:

  • Forged High-Silicon Aluminum Construction: Manufactured from high-silicon, low-expansion aluminum alloy for superior strength, reduced weight, improved heat transfer, and extended service life compared to cast alternatives.
  • Diamond-Turned CNC Finish: Precision-machined on CNC turning centers to guarantee a perfect surface finish with zero size variation, ensuring consistent fitment and performance.
  • Broad Cylinder Compatibility: Engineered for use in cast iron, chrome, Nikasil, and boron composite cylinder bore compositions, allowing confident installation across a variety of cylinder types.
  • Oversize Availability: Part of Wiseco's comprehensive oversize piston lineup, helping extend the life of worn cylinders. Compatible with replacement cylinder sleeves for chrome, Nikasil, and boron composite bores.
  • 82mm Bore Diameter: Sized at 82mm (3.228 inches) to match the Kawasaki 1100 ZXi engine specifications, including cross-reference designations 3228KD and 809M.

Easy and fast.

fast and easy

Lowest prices. Price of parts plus shipping was lower identical parts with free shipping.

Cool site.

Website is easy to use

the amazon payment did not work; hope I don't get double billed since I went with paypal afterwards. Meanwhile, I could not verify that my amazon order is cancelled/never placed.

Fast and simple!

Excellent service,super fast shipping,before I could get a tracking number, my package already arrived.<br>Will most definitely do business again.

I recently ordered the clover patch for my new 2012 Jeep Wrangler. The price for Autoplocity was the best I could find on the web and their shipping fees were also very affordable. I received my confirmation emails promptly and I was able to track the status of my order very easily. I enjoyed my experience ordering off of Autoplicity and I am likely to purchase additional products for my jeep off this site.

Name brand product was sold to me at a fraction of the local retailer's price. I will share with all my friends the value at this site!

Good price.
