A 400cc pro go-kart can reach speeds of up to 60 mph. This makes them one of the fastest categories of recreational karts available, offering an exhilarating experience for experienced drivers.
While 60 mph is a general top speed for 400cc karts, the actual speed can vary based on several factors, including the specific engine tuning, track conditions, driver weight, and the kart's setup.
Understanding Go-Kart Speeds by Engine Size
Go-kart speeds are directly related to their engine displacement, measured in cubic centimeters (cc). Larger engines generally provide more power and higher top speeds. Here's a comparison of common go-kart categories and their approximate top speeds:
| Go-Kart Category | Engine Size (cc) | Approximate Top Speed | Target Driver |
|---|---|---|---|
| Cadet Kart | 160cc | Up to 25 mph | Children |
| Adult Kart | 200cc | Up to 35 mph | Adults |
| Pro Kart | 400cc | Up to 60 mph | Experienced Adults |
Factors Influencing Go-Kart Speed
Beyond engine size, several elements contribute to a go-kart's overall performance and top speed:
- Engine Tuning: Fine-tuning the carburetor, ignition timing, and exhaust system can significantly impact power output.
- Gearing: The sprocket ratio between the engine and the rear axle determines acceleration versus top speed. A higher gear ratio favors acceleration, while a lower ratio allows for higher top speeds.
- Weight: Lighter karts and drivers generally achieve higher speeds and better acceleration.
- Track Conditions: Smooth, dry tracks with long straights allow karts to reach their maximum potential. Uneven surfaces or tight turns will reduce average speeds.
- Aerodynamics: While less significant than in cars, a kart's bodywork and driver's position can influence air resistance at higher speeds.
- Tire Grip: The type and condition of tires affect how efficiently power is transferred to the ground and the kart's cornering speed.
These factors combined determine the true on-track performance of any go-kart, including the powerful 400cc models.
