Description

Wildcat 70.50mm Flat Top Piston Kit – Lightweight Performance Upgrade


Upgrade your small-block engine with the Wildcat 70.50mm flat top piston, engineered for lightweight performance and optimized clearance for stroker applications. This high-performance piston is specifically designed to work with the Wildcat 223’s 58mm stroke crankshaft and stock-length connecting rod, offering increased compatibility and performance over standard 70mm factory pistons.


With a shorter skirt design and reduced overall weight, this piston allows for smoother engine operation, faster revving, and reduced internal resistance — making it ideal for mini bikes, go-karts, and racing builds.


Technical Specifications:

  • Piston Diameter: 70.50mm
  • Wrist Pin Diameter: 18mm (17.96mm / 0.7086")
  • Compression/Pin Height: .8835"
  • Piston Weight (Avg): 138g
  • Material: Lightweight cast alloy for improved strength and heat resistance


Weight Comparison:

  • Wildcat 223 Flat Top 70.5mm Piston: ~138g
  • Predator 212 Hemi Flat Top 70mm Piston: ~158g

Save 20 grams over the stock Hemi piston — for better throttle response and reduced reciprocating mass.


Fitment Note:

This piston does NOT fit:

  • Predator 224
  • Ducar/Tillotson 212E
    These engines use a different wrist pin size. You must use a Honda/Clone-based connecting rod for proper fitment.


Kit Includes:

  • Wildcat 70.50mm Flat Top Piston
  • Matched Piston Ring Set
  • 18mm Wrist Pin
  • 2x Circlips


Applications:

  • Wildcat 223
  • Clone 196/212cc Engines with 70mm bore
  • Engines using a 58mm stroke crankshaft with stock-length rod
  • Mini bikes, go-karts, and racing engines


This piston is perfect for performance enthusiasts and racers looking to optimize stroke compatibility and reduce internal engine mass without sacrificing durability.

FAQ

What engines is this 70.50mm piston compatible with?

This piston is designed to work with:

  • Wildcat 223
  • Clone-based engines with a 70mm bore
  • Any small-block engine using a 58mm stroke crankshaft and a Honda/Clone-based connecting rod


Can I use this piston in a Predator 212 or Tillotson 212E?

You can use this piston in a Predator 212 only if you’re also using a clone-style rod with an 18mm wrist pin.
It is not compatible with:

  • Predator 224
  • Tillotson/Ducar 212E
  • Ghost 212
    These engines use a different wrist pin size.


What’s the benefit of a shorter piston skirt?

Shorter piston skirts reduce friction, lower reciprocating mass, and allow the piston to work more smoothly with longer stroke crankshafts, such as the 58mm in the Wildcat 223.


What is the wrist pin size?

The wrist pin diameter is 18mm (17.96mm / 0.7086”), matching Honda/Clone-style rods.


What’s included in the piston kit?

  • 70.50mm Flat Top Piston
  • Piston Ring Set
  • 18mm Wrist Pin
  • Circlips (x2)


Does this piston improve performance?

Yes — it reduces weight by ~20 grams compared to a Predator 212 Hemi piston, allowing quicker revs, better throttle response, and improved engine tuning for high-performance applications.
