How fast will a Predator 212 go?

The Predator has a displacement of 212cc and can produce a little more than 6.5 hp, a new predator 212 engine is restricted to 3600 rpm, i.e, the engine shaft can at max rotate 3600 times per minute.

So how fast can your go-kart/minibike go with one of these blocks? Unfortunately, there is no straightforward answer and the top speed depends on your exact setup.

The top speed of your go-kart with a predator 212 engine will be 20-30 mph, the exact top speed will depend on the drive wheel’s diameter, gear ratio, and the engine’s rpm (3600 for a Predator 212).

Use Our Calculator below to find the top speed of your go-kart/minibike (Predator 212’s max RPM is 3600 by default):

What is drive wheel diameter?

The drive wheel is the wheel that is pushing the go-kart or minibike forward. Which is in most cases the rear wheels (located behind the seats).

How to find the diameter of your drive wheel?

Get a measuring tape or a simple scale and note the diameter of the rear wheel.

Gear Ratio

The gear ratio is the ratio between the angular speed of the engine’s crankshaft and the angular speed of the drive wheels.

How to find the gear ratio of your setup?

The gear ratio at any given moment depends on whether your go-kart is using a clutch or a torque converter. But since we are talking about the “top speed”, we don’t have to worry about whether you’re using a clutch or torque converter.

Gear Ratio = Teeth on Axle Sprocket / Teeth on Clutch

If you’re using jackshafts, then you’ll have to multiply the above value with (teeth on driver jackshaft/teeth on driven jackshaft)

Modified Predator 212

There are tons of performance parts available for Predator 212 that can significantly increase the RPM of the engine. Have a look at our Predator 212 performance mods guide to learn more about it.
