The 8 Highest CC Dirt Bikes You Can Buy! (Ultimate Power)

Are you looking for the ultimate power and performance in a dirt bike?

If so, you’ve come to the right place.

In this blog post, we’ll be looking at the 8 highest cc dirt bikes available, that offer the highest horsepower ratings for a dirt bike.

Providing you with detailed information on each of the models, by highlighting their engine size and power output, exploring their setup, and discussing their pros and cons.

Plus, we’ll also compare these top models head-to-head to see how they stack up against each other.

What Does “cc” Mean on Dirt Bikes?

For dirt bikes, “cc” is a common abbreviation that refers to engine size, cc stands for “cubic centimeters,” which is a unit of measurement used to describe the volume of an engine’s combustion chamber or cylinder head.

The cc represents the total volume of air and fuel that the engine can draw in during one complete cycle, which includes intake, compression, combustion, and exhaust.

Generally speaking:

• The higher the cc, the larger the engine size and the more power it can potentially produce.
• Dirt bikes with higher cc engines produce more torque and horsepower than those with lower cc engines.
• Higher cc bikes can provide better throttle response, stronger acceleration, and increased top speeds.

However, it’s important to note that the total power output depends on various factors, including the engine’s design, tuning, and efficiency, and not just its size.

Despite the engine updates, however, the KX450’s power delivery feels similar to the previous years with no noticeable increase in performance.

While very powerful, the bike in all honesty could benefit from more low-end power, especially in deep, muddy conditions.

One of the standout features of the CRF450R is its smooth and controllable power band.

The engine produces 56 horsepower, which is in line with other similar-sized bikes with comparable engine displacements.

However, recently Honda has made changes to the air boot, throttle body, intake ports, and valve timing to slow down the air entering the engine, resulting in a smoother and more rideable power delivery.

The CRF450R comes with a map switch offering standard, smooth, and aggressive modes, as well as traction control for starts.

While the rider triangle and overall geometry of the CRF450R are great, the stock suspension may not suit all riders.

The bike’s rear end has also received attention, with a new linkage featuring thinner wall thicknesses for increased flex, a smaller linkage bolt, and a redesigned swingarm that reduces chain friction.

While the engine remains unchanged, the Factory Edition comes equipped with an Akrapovič muffler, contributing to its impressive 50+ horsepower output.

The Husqvarna FC 450 is a top-tier motocross bike that shares many similarities with its KTM counterpart from above.

One of the key differences between the Husqvarna FC 450 and the KTM 450 SX-F though is ride height, as the FC 450 sits about one inch lower due to shorter forks, a modified shock, and a different linkage.

This lower center of gravity makes the bike easier to handle, particularly on smoother tracks and in hard-packed conditions, making it a popular choice among veteran riders.

The FC 450 also features a more closed-off airbox compared to the KTM, resulting in a smoother, more linear power delivery that’s easier to control.

Despite this, the bike still boasts an impressive 59 horsepower and 36 pound-feet of torque, thanks to its powerful engine that was updated in 2023.

The bike also comes equipped with WP XACT air forks, which offer improved weight savings and performance compared to traditional spring forks.

The 450 SEF has a torquey engine with a strong low-end and good traction, particularly in first and second gear. However, the power delivery can be a bit abrupt, causing a “herky-jerky” feeling when slipping the clutch in tight situations.

Ergonomically, the Sherco 450 SEF has a KTM-like feel, with a tall, flat seat, a low-bend handlebar, and easy-to-use controls.

The suspension on the 450 SEF features KYB shocks, which offer good handling over small bumps and rocks but can feel a bit soft under aggressive riding.

The YZ450F is known for its powerful engine, which produces nearly 59 horsepower on the dyno, making it one of the most powerful bikes in its class.

The engine’s strong bottom-end and mid-range power, combined with a high rev limiter and long second gear, make it easy to pull holeshots and maintain speed on the track.

The bike’s ergonomics were updated last year, featuring a taller seat-to-footpeg height and seat-to-handlebar distance, creating a more comfortable riding position.

However, some riders have complained that the seat is too thin and uncomfortable for long rides, requiring aftermarket modifications like the Guts seat cover with wings or a wider seat foam.

The YZ450F’s handling is nimble and quick, and its KYB suspension provides good balance and turning performance.

However, the front end can feel a bit twitchy at high speeds.

The Yamaha YZ450F is a fast, nimble, and confidence-inspiring bike, which is why it has been a leader in the 450cc motocross class for years.

Factors to Consider Before Choosing a High CC Dirt Bike

When choosing a high cc dirt bike, there are several factors you should consider.

Skill Level

First, you should consider your riding experience.

Beginner riders typically find high-displacement bikes overwhelming and challenging to control. Because of this, they’re better off starting with a lower cc bike like a 125 or a 250 to build their skill level and confidence.

High-cc dirt bikes are designed and intended for advanced riders with ample experience who can handle the power and performance of the larger engine and who have a solid handle on both basic and advanced riding techniques.

So before hopping on a high-performance 450 bike, as tempting as it may be, it’s always a good idea to be honest with yourself about your current skill level.

As this will help you avoid biting off more than you can chew or worse yet getting hurt or injured.

Intended Use

Another important factor to consider when choosing a high cc model is your intended use for the bike.

Think about the type of riding you plan to do most, as this will influence your choice of dirt bike.

For example, if you’re interested in motocross racing, a bike with strong acceleration and handling, like the Yamaha YZ450F or KTM 450 SX-F, may be a good choice.

However, if you’re more focused on off-road adventures and technical terrain, a bike with good traction and maneuverability, like the Gas Gas MC 450F or Sherco 450 SEF, might be a better option.

Budget

Budget is another important consideration when selecting a high cc dirt bike. As these bikes can vary significantly in price.

So it’s important to determine your budget before making a choice.

When considering your budget it’s also important to keep in mind not only the initial purchase price but also ongoing maintenance and repair costs.

As more widely available brands, like Suzuki and Kawasaki, are generally less expensive to maintain compared to more exotic brands like KTM, Husqvarna, Gas Gas, and Sherco.

Brand Reputation

While every bike on this list is from a premium dirt bike brand, it’s still a good idea to research the reputation and reliability of different brands and their models to ensure you choose a high-quality, dependable machine.

Look for brands with a proven track record of producing durable, high-performance dirt bikes, like Honda, Yamaha, KTM, and Husqvarna.
