This engine is highly regarded for its affordability, reliability, and ease of modification. With a 3.54 in (90 mm) bore and 2.43 in (61.7 mm) stroke, the engine has a compression ratio of 8.5:1, allowing it to produce around 6.5 horsepower at 3,600 RPM and 8.1 ft-lbs of torque at 2,500 RPM in its stock configuration.
The engine is equipped with a recoil starter for easy starting. It features a horizontal shaft design, which makes it suitable for a wide range of applications. The Predator 212 also has a fuel tank capacity of 0.95 gallons (3.6 liters). This allows for extended usage between refueling stops.
Additionally, the engine is designed to run on unleaded gasoline with an octane rating of 87 or higher, ensuring efficient performance and reduced emissions.
How Fast Will a Predator 212 Go
The top speed of a Predator 212 engine on a go-kart, under ideal conditions and in its stock configuration, can reach up to 35 mph. However, this speed may vary depending on factors such as the weight of the vehicle, the terrain, the gearing setup, and any modifications made to the engine.
By upgrading the engine with performance parts, it’s possible to achieve even higher speeds, although this may require additional tuning and maintenance.

Factors Affecting Top Speed
Several factors can affect the top speed of a go-kart or minibike with a Predator 212 engine:
- Drive wheel diameter: The size of the drive wheel impacts the top speed. Larger wheels cover more ground per revolution, potentially increasing speed.
- Gear ratio: The gear ratio determines how many revolutions the engine makes for each revolution of the drive wheels. A lower gear ratio provides more acceleration, while a higher gear ratio offers a higher top speed.
- Engine RPM: The maximum RPM of the Predator 212 engine is restricted to 3600, but modifications can increase the RPM and top speed.
Modified Predator 212
Enhancing the Predator 212 engine with performance parts can increase the engine’s RPM and top speed. Many modifications, such as aftermarket exhausts, carburetors, and air filters, are available. Remember that modifying your engine may void its warranty and may not be legal in some areas.
The top speed of a go-kart or minibike with a Predator 212 engine varies depending on factors such as drive wheel diameter, gear ratio, and engine RPM. Typically, these vehicles can reach speeds between 20-50 mph, with modified engines achieving even higher speeds.
