Product Details

The Wiseco 4418M07450 is a high-performance forged piston kit designed specifically for Kawasaki KSF250 Mojave (1987-2003) and KFX250 Mojave (2004-2005) ATVs. This piston is manufactured at .020" (0.50mm) oversize with a 74.5mm bore diameter, making it ideal for engine rebuilds and performance upgrades.

Key Features:

  • Forged in-house in the USA for superior strength and durability
  • 74.5mm bore diameter (.020" / 0.50mm oversize)
  • Condensed grain structure aligned to part features for maximum strength-to-weight ratio
  • Enhanced resistance to impact and fatigue compared to cast pistons
  • Optimized for extreme racing conditions and high-performance applications
  • Includes precision skirt coating for reduced friction and wear

Wiseco's forging process creates a denser, tougher piston that resists catastrophic failure under high-stress conditions. Unlike brittle cast pistons, these forgings maintain structural integrity even when subjected to the demanding requirements of motorsport applications. Each piston is engineered with meticulous attention to detail, from raw material selection through final finishing.

I searched everywhere. Autoplicity has the best price.

The buying process is fast and easy

Nice site, easy to use and had what i needed

Awesome place to shop. prices are great as well

Quick and easy. Could have left or right side in description though. Other than that 1 phone call cleared up the left and right confusion and placed my order. Great service. I even used again for my rear Lateral arms I just purchased

It was fast and easy

excellent

Easy steps go follow. I had a couple of hiccups in registering but overall it went well.

I placed an order with autoplicity on Saturday order number 10468 I got it today and installed my new banks ram air box and it is awesome. Thanks autoplicity my box from Banks looks like it just came off the shelf even after ups delivered it.

Great buy and fast shipping very happy.

So I have an old car. It's and 83, seven years older than me. I'm also a student so I don't have much money and need to make as many repairs myself to save money. I go out to the local pep boys and auto zone to to try to find a repair manual that is for my old model but it's not available. I check online and there are very few copies on line. Autoplicity had the right manual at the lowest price by a good margin. <br><br>TLDR; Autoplicity has EVERYTHING and at a cheaper price

Oh my god, my car rips now. Scary improvement. Will buy again, and aeromotive will have my lifetime support. Much love!!!
