The Yerf Dog 42101 is a single-seater version of the Spiderbox GX150 go-kart. It’s equipped with the same 150cc hp engine, which has an output of 7.8 hp at 7,500 rpm. 

This Yerf Dog model is perfect for people who love to race off-road alone, instead of having a passenger with them. The 42101 is able to handle any type of terrain thanks to pneumatic tires and high-quality independent suspension system. 

Moreover, the comfortable bucket seat and the safety belt ensure that the driver is well protected at all times. Driving his go-kart at night is also possible, due to its bright headlights, which are mounted on top.

3. Yerf Dog 3203

Go-Kart Features

  • Output: 6.5 hp
  • Capacity: 2
  • Max Weight: 250 lbs

The Yerf Dog 3203 is a smaller sized off-road version of the Spiderbox GX150 and is one of the most popular Yerf Dog go-karts. It seats one driver and a passenger. 

Although it features a sturdy build and has enough room for two people, it’s not as spacious as the Spiderbox go-kart. However, it still packs a punch with its 6.5 hp Tecumseh engine. 

Due to its compact size, it’s great for youths or smaller adults that enjoy off-road racing with passengers. It has a basic suspension system and a three-point safety harness for both occupants. 

Instead of seats, the Yerf Dog 3202 has a well padded bench. Additional features include a storage rack, racing flag, a padded roll cage and racing decals. If you’re looking for a more affordable two-seater Yerf Dog, then this may just be the one for you. 

4. Yerf Dog 3002

Go-Kart Features

  • Output: 6 hp
  • Capacity: 2
  • Max Weight: 200 lbs

Another favorite and best seller is the Yerf Dog 3002. This model comes with a gas-powered 6 hp Tecumseh engine and a torque converter. Due to its compact size and powerful performance, the 3002 is ideal for youths above the age of 16 years. 

Although its form factor is on the smaller side, it still has a maximum capacity of 2. However, take note that the maximum combined driver and passenger weight is only 200 lbs, therefore making it ideal for youths. 

The 6 hp engine packs quite a punch, even if the compact form factor may tell otherwise. Equipped with a suspension system, a padded bench and roll cage, as well as three-point safety belts, this Yerf Dog 3002 is comfortable to ride on nearly any surface. 

However, it does not have bucket seats or headlights, so do keep that in mind. Overall, the 3002 is a great single or two-seater off-road go-kart for youths and young adults.

5. Yerf Dog 30032

Go-Kart Features

  • Output: 5 hp
  • Capacity: 2
  • Max Weight: 250 lbs

Another great two-seater Yerf Dog go-kart that has been quite popular is the 30032. It’s also fairly compact in size and is therefore ideal for youths above the age of 16 years. 

This model comes in three different colors, a yellow version (30032), a blue version (30033) and a red version (30034). All models come equipped with a gas-powered 6 hp Tecumseh engine.

It’s slightly less powerful than the 3203, but is still able to provide an enjoyable off-road racing experience. The slightly narrower frame means that it’s suitable for an average sized racer. 

It can get a little squeeze for two people but it’s definitely still possible. Overall, the 30032 caters to a younger audience, while still having many – but not all – of the features of the higher end models.

Yerf Dog Go-Karts: Buyer’s Guide

In this section, I’ll be sharing with you what type of aspects to consider, before purchasing a Yerf Dog go-kart. Here, you’ll find information about the different go-kart types, capacities, performance, upgrades, features and prices. 


Yerf Dog go-karts are generally designed for all types of terrains. This makes them great off-road go-karts, thanks to their suspension system, padded seats and large pneumatic tires. 

Therefore, if you’re looking for a more intensive off-road racing experience, you should select a Yerf Dog with an independent suspension system and padded bucket seats, to ensure a comfortable ride on rough terrain. 


Most go-karts in the Yerf Dog line are designed for two people – one driver and a passenger. However, take note that there are also single-seater Yerf Dog go-karts like the 42101.

Therefore, it’s best to select a Yerf Dog model that suits your application. For larger families who enjoy off-road racing, I would advise to get a two-seater Yerf Dog. The great thing is that you can also drive the two-seater models without a passenger. 


Performance is another thing that you should consider, before deciding which model best suits you. All Yerf Dog engines are gas-powered. The Tecumseh engines range from about 5 hp to 7.8 hp. 

If you’re looking for a more thrilling off-road racing experience or are an adult, the higher output engines as found on the 3206 (Spiderbox GX150) and the 42101 would be more suitable. 

For youths above the ages of 16, a lower-powered engine is recommended. There are several 5 hp and 6 hp engines available for that, for example on the Yerf Dog 3203, 30032 and 3002. 


If you’re a hobbyist, builder or are looking to modify your go-karts, then you should definitely consider checking out my guide on Yerf Dog upgrades. The Yerf Dog model you get may not have all features available. 

Additional features that you may want to upgrade are bucket seats, an independent suspension system, headlights, fog light and various other things. Keep the ability to upgrade in mind, when selecting a model to purchase, if that is what’s important to you. 


While most models come with similar features, they can vary between models. All Yerf Dog go-karts come with a durable metal frame and rubber tires, but the seats are often different.

Many people buy and sell these iconic go-karts for just a fraction of what they used to cost. You’ll be able to find a used Yerf Dog go-kart for about $300 – $1,000, with newer and better models being slightly more expensive.
