Buying Guide: How to Choose Go-Kart Racing Engines

The list above represents a good range of entry-level to intermediate go-kart engines. Of course, you’ll need to decide what type of go-kart you have or are planning to build, in order to decide which engine is best for you.

It’s worth to note that there are also other aspects that you should take into consideration, in order to make an informed purchase decision. In this buying guide we’ll take a more in-depth approach to understanding the various other aspects that are important to know. These aspects include the go-kart engine’s performance, shaft orientation, efficiency, size, features and price. Let’s take a look!


The performance of the engine should be one of the most important things you should take into consideration. If you’re building or replacing an engine for a racing or an off-road go-kart you should consider a more powerful engine. This is because racing go-karts require greater power, in order to accelerate faster and reach higher top speeds. Off-road go-karts also require more power as they typically race on uneven surfaces and rocky terrain. If you’re buying an engine with the intention to build a go-kart yourself or if the go-kart engine is for kids or teenagers, you should consider a lower powered engine. 

In order to understand how to read performance indicators of an engine, the next section will help to explain horsepower, displacement, torque and running speed. 

Horsepower (hp)

The power of a go-kart engine is expressed in horsepower (hp). This output value is defined by the displacement, design, running speed and torque of the engine. For example, the DuroMax XP7HPE has a maximum output of 7 hp. For reference, 1 hp equated to 746 watts (0.746kW). To illustrate this, a 1 hp engine can list 330 pounds 100 feet in a minute.

Displacement (cc)

The displacement of an engine indicates the total volume that all cylinders can hold. Go-kart engines usually run on one-cylinder engine. The unit of measurement for displacement is cubic centimeters (cc). The bigger the displacement value, the larger the engine is.

Torque (ft/lb)

The torque of a go-kart engine measures the rotational effort that the piston is applying to the crankshaft. Simply put, it can be understood as the ‘turning force’. This is measured in foot-pound (ft/lb) or Newton-meter (Nm). For example, the Titan TX200 produces 9.1 ft/lb. The greater the torque value, the more powerful the engine.

Running Speed (rpm)

RPM is a measurement that indicates how many revolutions per minute a crankshaft is doing. Go-kart engines have a typical rpm range of around 2,500 to 10,000 rpm, depending on how powerful the engine is.

Shaft Orientation

You also need to understand what type of shaft orientation you require for your go-kart. Go-kart engines can have a vertical or a horizontal shaft orientation. This also influences the shape of the engine. If you’re replacing an existing engine, you should definitely match the shaft orientation of the engine that you are replacing. 

If you’re building a kart from scratch, you’re free to choose. Keep in mind that horizontal and vertical shaft engines are differently shaped. Below illustration will show the shape and design differences. Most go-karts use a horizontal shaft engines, due to space constraints on the frame. 

go-kart engine with horizontal camshaft

Engine with Horizontal Camshaft

  • Camshaft orientation is horizontal
  • Requires more vertical space
  • Mostly used for go-karts
go-kart engine with vertical camshaft

Engine with Vertical Camshaft

  • Camshaft orientation is vertical
  • Requires more horizontal space
  • Mostly used for lawn mowers


The efficiency of a go-kart engine is important to understand, as well. If you are running a very inefficient engine you not only unnecessarily pollute the environment but you’ll also have to fork out more money for gas. An engine’s efficiency is defined by how much fuel it uses, in order to operate. To put this into context for go-kart racing engines, we’re looking at the fuel efficiency of the engine.

Let’s take the DuroMax XP7HPE as an example. This engine is rated with a fuel consumption rate of 0.25 gallons of fuel per hour at half load. This means that running this engine at half its maximum load will consume a quarter of a gallon per hour, which is very fuel efficient. Of course, the fuel efficiency of a go-kart engines depends on the load it’s used at and how powerful it is.


When it comes to go-kart racing engines it’s apparent that they all vary in sizes. Some are smaller, some larger but there are also other measurements that you should take into account, especially if you’re replacing an existing go-kart engine. These measurements usually revolve around the engine itself and the shaft. 

The reason why this is important is because your other go-kart components need to be compatible with these measurements, in order to function properly. Here’s a list of engine measurements that you should check before you make your decision:

  • Engine Dimensions
  • Shaft Size
  • Shaft End
  • Center of shaft to base


Go-kart engines have some basic features, which are all the required components. Each engine is equipped with the standard components which are a shaft, cylinder, housing, fuel tank and an oil tank. Some go-kart engines have additional features that you may want to consider. Below is a list of additional go-kart engine features that you are able to see on the high-quality engines.

Additional Engine Features

  • EPA & CARB certification
  • Increased fuel efficiency
  • Automatic shutdown sensor
  • Dual element air cleaner
  • Electric starter
  • Splash lubrication system
  • Throttle-ready

Go-kart engines have a very wide price range, depending on the features that it offers and the performance of the engine. There are beginner engines that start at around $140, intermediate engines that start at about $220 and professional engines that start at about $350.

Everyone has a budget to work with and there’s an engine for even a shoestring budget. Decide what price range you are comfortable with and select an engine that fits in that price category. This list below shows a summary of go-kart engines prices according to their level:

  • Beginner Go-Kart Engine: around $140 to $220
  • Intermediate Go-Kart Engine: around $220 to $350
  • Professional Go-Kart Engine: around $350 to $1,200

Frequently Asked Questions

From time to time I get asked about go-kart engines, whether it’s in person, via emails or comments. I’ve compiled a list of frequently asked questions below. If you have questions that are not found in this list, please get in touch with me and I will have them added. 

What Type of Go-Kart Engine Should I Buy?

I often get asked if I can suggest an engine for a particular go-kart. While I love to give recommendations, the answer to the question of which go-kart engine is best, only you know. I believe that this list should give you an overview of what the best go-kart engines are, but ultimately you must be able to decide which one to go for. If you give me some details in the comments, I’m happy to chime in and give a recommendation.

As a general rule of thumb, you should pick an engine based on performance and price. There is a sweet spot, but make sure that you know what type of go-kart engine you are looking for and allocate a budget to how much you are willing to spend on a go-kart engine.

Two of the best go-kart engines are the Tillotson 212cc and the Predator 212cc. I’ve written a comprehensive guide comparing both, if you need more information to decide which one is better for you.

How Do I Find My Engine Dimensions and Measurements?

The engine dimensions and shaft measurements can all be found in the owner’s manual that your go-kart came with. If you’ve already replaced your go-kart engine before and bought an engine separately, the measurements can be found in the engine’s handbook. If you’re buying a brand new engine and have no reference, you can always check the dimensions and measurements on the manufacturer’s product page.

How Do I Clean My Go-Kart Engine?

Go-kart engines can become dirty relatively fast, especially if you own an off-road go-kart or a racing go-kart. Your engine can stain very quickly and be covered in grease, oil or mud. If that’s the case, you can resort to these general cleaning instructions below. 

  1. Make sure that your go-kart is stationary and the engine is off
  2. Use a high-quality engine degreaser and apply it to areas of grease or oil
  3. If you own an off-road go-kart, run down the mud with water gently first
  4. After applying the degreaser, simple take a moist cloth and the grease should come right off
  5. Rinse the towel and repeat the process without applying the degreaser
  6. Let the engine’s exterior dry by wiping it with a dry towel this time
  7. Ensure that there is no water left on the engine and it’s completely dry 


I hope this review and buying guide was able to help you identify what the best engines are for go-karts and that it also managed to give you an understanding of the various key components and aspects of a kart engine. I hope that this article has made your buying decision easier and that you were able able to find an engine that suits your performance and budget.

21 thoughts on “10 Best Go-Kart Racing Engines in 2022”

  1. It was worth reading this article. I was needed a racing engine for my Go-kart. You provide some great resources for Go-kart racing engines.
    I was a little skeptical about my Air filters. How often do I need to change my Go-kart Air Filters?

    • Hi Allen,

      Thanks for your generous comments! Glad this helps.
      With regards to air filters, for leisure useage I clean them after about every 10 – 12 hours of use.
      I know people who do this after every race depending on where they race.

      If you race competitively, it’s common to replace them after every race.

  2. Really appreciated this. My brother and I are building one for off-road and we are two big boys. We were looking at a 18hp duro max. You think that’s too powerful?

    • Hey Tyler!

      That sounds like an awesome project! It definitely depends on how heavy the off-road go-kart is and if it’s a one-seater or two-seater.
      For single seater lightweight karts, I would say 6 – 12 hp would suffice. For larger, more powerful ones 12 – 18 hp would work for sure.

    • Hi Raph,

      The Honda GC 160 is an air-cooled 4-stroke engine that is more than sufficient to build a go-kart or to replace an existing engine on a go-kart.

  3. Sure appreciate the article!
    Can I get aftermarket parts like intake, exhaust, etc for the B&S CR950?
    It seems to be the smallest engine in dimensions and I have limited space on my project.

    • Hi David,

      Thanks for the kind words!

      You sure can! However, just make sure that the engine measurements are workable for your project.
      Also check the specifications of the aftermarket components and see if they are compatible (e.g. manifold, hoses, etc.)

  4. i recently built a cart with 18 horse 440cc duromax at high speed we get a poping or grinding noise sounds like clutch or chain and sproket no idea any help would b great

    • Hi Will,

      I would check the chain tension and clutch condition.
      Accelerate your kart slowly on a stand so that you can inspect.

  5. No offense to your list but the tillotson 212 should definitely be on here as it is in fact the better than any engine on this list. I’ve owned three of these engines aswell and nothing performs like the Tilly

    • Hey Shawn! All comments are welcome 🙂
      In fact this list was updated constantly with helpful inputs from the community such as yours, so thank you for that!
      I have heard about it but never had the change to try it! I will give it a try, review it and rank it in the next update.

  6. Me and my friend are trying to plan out a drift cart. Do these engines have enough power to keep the wheels spinning through a turn? It’s only going to be single person cart so it wont be too heavy. Any recommendations on other engines even?

    • Hi John,

      Yes, these will definitely let pretty much any type of go-kart drift.
      Just make sure that you set it up as a RWD and get the right tires/wheels
      The surface is also very important!

  7. I’m looking for a solid off-road cart similar to a rail which I cannot afford, but I would like the 23 hp predator and I’m not quite sure what to buy and helps modify and weld, spot weld or mig. I found the engine at Harbor freight for $1000. all I really need is a machine that the second time I get on that I’m second-guessing whether I want to take that ride. Just something ridiculous. Now if I was going Street can you remember when they used to use chainsaw engines and they were duel on racing carts? Or am I just having memory impairment? Lol last thing I remember they were fast as hell? What is suggested for just a ridiculous reason cart pushing 85 mph sets out that? Thanks a lot! Sean

  8. Back when I raced karts the 2 top classes were limited modified and modified Briggs motors. What are the top classes and fastest motors now?
