Looking for a seamless engine startup every time? It may be time for you to make the switch to a fuel-injection dirtbike. You just need to know which models to look for.
Leading manufacturers, such as Yamaha and KTM, started releasing models of dirt bikes with fuel-injection systems around 2009. Since then, other manufacturers have joined the fray. Today there are many different types and models of dirt bikes using advanced ignition technology.
There are many advantages to this, as will be discussed in greater detail later on. You’ve come to the right place to find insider info on which bikes are the best on the market today, including both 2-stroke and 4-stroke engines.
Ever since fuel-injection technology debuted in dirt bikes in the early 2000s, more and more dirt bike manufacturers have made the switch from carburetors.
The primary advantage of fuel-injection systems is that they can power your bike smoothly through all conditions. It doesn’t matter if the weather is hot or cold, wet or windy.
Yes, carburetors are easier and cheaper to repair, but these days EFI is so reliable that repairs should not be a major concern.
Yamaha is one of the true stalwarts of motorsports. Chances are, you’ve probably owned or ridden a Yamaha dirt bike at some point in your life.
The good news here is that the company does offer fuel-injected dirt bikes.
Yamaha made waves when it introduced the fifth-generation YZ450F, a four-stroke dirt bike with a fuel-injection system. Additional features, such as a new crank rod angle, were designed to improve fuel delivery.
The 6th and 7th generation (current model) YZ450Fs also carry EFI, albeit with minor tweaks to engine components:
- Yahama YZ450F 5th Generation: 2010-2013
- 6th Generation: 2014-2017
- 7th Generation: 2018-Present
Suzuki was the first to introduce a fuel-injected motocross bike back in 2017. Currently, the company offers several EFI models, some of which are among the most powerful available on the market today.
Take for example the RM-Z250, which has not one, but two fuel injectors. Yes, you read that correctly! One of these is specifically designed for low RPMs and the other is there for high RPMs.
2009 was the first year that Honda began to roll out fuel-injected dirt bikes. By 2019 the company had 4 different fuel-injected models available for sale: the CRF110F, the CRF125F, the CRF250F, and the CRF450X.
The 450X is an absolute beast of a machine. With a 449cc liquid-cooled single-cylinder four-stroke engine and a wide-ratio six-speed transmission optimized for just about any terrain, you throw at it.
You may have begun to sense a common theme here as to when fuel injection was first introduced in dirt bikes. Following suit, Kawasaki began offering EFI bikes in 2009, with the KX450F.
Today the company offers 5 different fuel-injected models:
- KX 250
- KX 450
- KX 450SR
- KX 250X
- KX 450X
The big difference here between the X models and the others is that the X models are cross-country bikes. As such, these are built to handle a wider range of terrain than the other models.
Some riders prefer 2-stroke dirt bikes because they are easier to maneuver and require less maintenance. One potential downside is that it offers less torque than 4-stroke bikes.
That being said, 2-stroke bikes are an excellent choice for most, especially the weekend warriors. Stay tuned below for a listing of some of the best fuel-injected 2-stroke bikes on the market.
KTM is a manufacturer based out of Austria that manufactures both 2-stroke and 4-stroke bikes. Fuel-injected 2-stroke models were first unveiled by the company back in 2017.
KTM is among the leaders in terms of variety with its fuel-injected lineup. One of the most impressive features is the horsepower of the 300 SX. Despite the engine weighing just 52 lbs, it churns out 57 HP.
In 2017 Husqvarna also introduced its 2-stroke fuel-injected bike, the TE250i. You might be surprised to hear that this model does not require fuel mixing, a rarity among 2-strokes. Oil is stored near the gas tank and is mixed in automatically.
Husqvarna makes the bold claim of calling the 150i an “ultra-lightweight”. A look around the market does indeed back up this claim. At 232 pounds, the 2022 150i model is considered one of the lightest enduro models in the world.
For those in search of good starter dirt bikes for kids, then the Honda CRF110F is certainly a solid choice. This bike has a four-stroke engine, and a fuel injection system and is designed for youth.
You’ll find that most youth dirt bikes have carburetors. Even in the KTM SX series, which has converted to fuel injection in the full bikes, the youth bike has a carburetor.
Yes, you may have already noticed this. Fuel-injected bikes are certainly more expensive than carburetors. The major plus here is the benefit of not having to constantly finagle with the carburetor.
We’ve seen the full switch in the auto industry, due to the massive performance upside. In dirt bikes, it means that you’ll get a little extra horsepower and won’t have to regularly clean the gunk out of the carburetor.
One motivation for putting an end to carburetors is the environment. Carburetors are not efficient and they give off more tailpipe emissions than fuel injection systems.
In some locales, tight restrictions on emissions could make it more challenging for manufacturers to push out dirt bikes with carburetors.
These days you can find a wide selection of dirt bikes with direct fuel injection. There are so many on the market today that many riders find themselves indecisive. The sections above should serve to introduce you to today’s most popular bikes.
