GX200 Crankshaft Specs and Fitment
Understanding crankshaft specifications ensures proper compatibility with your engine:
- Stock Stroke: Approximately 2.123 - 2.125 inches
- PTO Size: Must match your clutch or torque converter
- Rod Journal Size: Must match your connecting rod 1.180 MAX
- Engine Compatibility: GX200 and most 196cc clone engines
Matching these specs is essential for correct installation and long-term reliability.
OEM vs Performance Crankshafts (Know the Difference)
OEM GX200 crankshafts are designed for stock engine performance and reliability.
Unlike performance crankshafts:
- OEM crankshafts are not dynamically balanced for high RPM racing
- They are not intended for extreme performance builds
- They are designed for standard operating conditions and longevity
If you are building a high-performance or racing engine, a billet or performance crankshaft may be required. For standard rebuilds and everyday use, OEM crankshafts are the correct choice.
Compatible Engines and Applications
GX200 crankshafts are widely used in:
- Honda GX200 engines
- 196cc clone engines
- Go-karts and minibikes
- Utility and recreational small engines
They are ideal for restoring engines used in both work and recreational applications.
Why Choose GX200 Crankshafts

GX200 Crankshaft FAQ
What does a GX200 crankshaft do?
It converts the up-and-down motion of the piston into rotational force to power the engine.
What is the stock GX200 crankshaft stroke?
Approximately 2.123 - 2.125 inches.
Are OEM crankshafts balanced?
OEM crankshafts are manufactured to factory balance standards but are not dynamically balanced like performance crankshafts.
Do I need a performance crankshaft?
For standard use and rebuilds, an OEM crankshaft is the best choice.
Billet Flywheels for Honda GX240 / GX270 Performance Engines
ARC Racing billet flywheels for Honda GX240 and GX270 engines are engineered for strength, durability, and reliable ignition performance in high-RPM racing environments. CNC-machined from billet aluminum and SFI certified, these flywheels provide a high-strength replacement for the stock cast flywheel used in factory engines.
ARC GX240 and GX270 billet flywheels use powerful rare-earth magnets that generate a strong magnetic signal to the ignition coil. This produces a hotter and more consistent spark while maintaining stable ignition timing for performance engine builds and racing applications.
Compatible Engine Platforms
- Honda GX240 Engines
- Honda GX270 Engines
- Predator 301 Engines
These engines are commonly used in kart racing, mini bikes, racing mowers, and other high-performance small engine builds where reliable ignition timing and strong rotating components are essential for safe operation.
Why Choose ARC GX240 / GX270 Flywheels?
- Precision-machined billet aluminum construction
- SFI certified for racing safety
- Strong rare-earth magnets for reliable spark output
- Designed for GX240, GX270, and Predator 301 engines
- Trusted by racers and professional engine builders
Whether you're upgrading a kart racing engine or assembling a performance GX240 or GX270 engine build, ARC Racing billet flywheels deliver the durability, ignition stability, and reliability serious builders demand.
GX240 / GX270 Flywheels – Frequently Asked Questions
Why upgrade to a billet flywheel on a GX240 or GX270 engine?
Billet flywheels are significantly stronger than stock cast flywheels. Upgrading to an ARC billet flywheel improves ignition stability and provides safer operation in high-RPM racing engines.
Do ARC GX240 / GX270 flywheels use the stock coil?
Yes. Most ARC billet flywheels for GX240 and GX270 engines are designed to work with the factory Honda ignition coil and stock pull starter.
Do ARC flywheels fit Predator 301 engines?
Yes. Some ARC billet flywheels designed for the GX240 and GX270 platform will also fit the Predator 301 engine due to similar crankshaft taper and engine design.
Do billet flywheels increase horsepower?
Billet flywheels do not directly increase horsepower, but they improve ignition stability and allow engines to safely operate at higher RPM in performance and racing applications.
Are ARC flywheels used in racing engines?
Yes. ARC billet flywheels are widely used in kart racing, mini bike engines, racing mower engines, and other high-performance small engine builds.
