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 GX120 Performance Engines
ARC Racing billet flywheels for the Honda GX120 engine are designed for durability, reliable ignition timing, and safe operation in high-RPM racing engines. CNC-machined from billet aluminum, these flywheels provide a strong and reliable replacement for the stock cast flywheel used in factory GX120 engines.
ARC GX120 flywheels use powerful rare-earth magnets that generate a strong magnetic signal to the ignition coil, helping produce a hotter and more consistent spark. This improves ignition reliability in kart racing engines and performance small engine builds operating under demanding conditions.
Compatible Engine Platform
- Honda GX120 Engines
- GX120-Based Kart Racing Engines
- GX120 Performance Engine Builds
The Honda GX120 engine is commonly used in kart racing and performance small engine builds where reliable ignition timing and strong rotating components are essential for safe engine operation.
Why Choose ARC GX120 Flywheels?
- Precision-machined billet aluminum construction
- Strong rare-earth magnets for reliable spark output
- Designed specifically for Honda GX120 engines
- Stable ignition timing for racing engines
- Trusted by racers and professional engine builders
Whether you're upgrading a kart racing engine or assembling a performance GX120 engine build, ARC Racing billet flywheels deliver the durability, ignition stability, and reliability serious builders demand.
Honda GX120 Flywheels – Frequently Asked Questions
Why upgrade to a billet flywheel on a GX120 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 GX120 flywheels produce a stronger spark?
Yes. ARC GX120 flywheels use rare-earth magnets that generate a stronger magnetic signal to the ignition coil, helping produce a hotter and more consistent spark.
What timing is built into the flywheel?
ARC GX120 billet flywheels are typically designed with approximately 30 degrees of ignition timing built into the keyway when using the standard key configuration.
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 GX120 flywheels used in racing?
Yes. ARC billet flywheels are commonly used in kart racing and other performance small engine builds where durability and reliable ignition performance are critical.
