Ten Fastest Dirt Bikes In The World

Motocross is a form of off-road motorcycle racing held on enclosed off-road circuits, Some Dirt bikes can hold out speed on their own. Granted, these bikes are rated for other attributes that are more important than speed, including suspension and the power levels of the gears.

The sport evolved from motorcycle trial competitions held in the United Kingdom. There is a list of street-legal production motorcycles ranked by acceleration from a standing start, limited to 0 to 60 mph times of under 3.5 seconds, and 1⁄4-mile times of under 12 seconds. The widely varying testing methodologies mean that, even between identical motorcycles, the acceleration times vary.

Some of these differences include the rider skill and launching technique, measuring equipment, track surface conditions, weather, air temperature, and altitude. You may be tempted to see how fast your model can go when you are out doing jumps and climbs on dirt roads to make your experience more exhilarating. If you want a particularly fast dirt bike, consider the following bikes to choose your preferred option.

Here in this article, RNN will highlight the fastest dirt bikes in the world.

1. KTM 450 SX-F (Dirt Bike)

The KTM 450 SX-F engine sits at the pinnacle of the 4-stroke motocross range, delivering a compact, single overhead camshaft design with the latest electronic injection system, resulting in unbeatable power. It has the ability to deliver usable power throughout the rev range while combining class-leading electronics, and adjustability not to mention being the lightest 450 cc motocross engine on the market.

Part of the KTM 450 SX-F’s acceleration comes courtesy of years of refining gear rations to ensure the best performance possible from the large displacement engine. The transmission is also engineered to be ultra-lightweight but has the durability to perform race after race.

The state-of-the-art KEIHIN Engine Management System, with electronic fuel injection, features a 44 mm throttle body. The injector position guarantees optimal atomization of the fuel and air on the way to the combustion chamber, resulting in instant response and maximum performance when opening the throttle.

2. Suzuki DR-z 50

The DR-Z50’s engine has a smooth power band with peak power that can be controlled via the adjustable throttle limiter that allows supervising adults to control engine output to suit the rider’s ability. Starting the DR-Z50 requires a simple push of the electric start button. Riders can also kick-start the bike, so a fun day of riding is always available.

The easy-to-use automatic clutch smoothly transmits power through the three-speed transmission, so beginning riders learn key-shifting techniques while discovering the joy of riding. Don’t be fooled by the DR-Z50’s light weight: It has a durable steel frame and swingarm designed to carry a wide range of riders and can easily tackle a variety of riding conditions.

Strong braking performance is provided by front and rear drum brakes. Adjustable front brake lever fits a variety of different-sized hands for optimum young rider control.

3. Aprilia RXV 550

The first Aprilia RXV550 to hit the market in 2006 was an animal. It was scary. It had a light switch for throttle and more ponies than the Ponderosa. On a test day, while doing 140kph on a flat dirt road, I listened to the rear wheel screaming for traction and wondered how you’d ever get the thing up a hill – and how I was going to pull up at the next corner. I wasn’t keen to get back on it any time soon, and yet here I am, all suited up and ready to roll on the 2007 model of the wicked Italian.

It’s hard to know where to start when describing the RXV. Its predominantly black and red colour scheme is striking, as is Lion’s head on the radiator shrouds and the super aggressive front and rear guards. Then there’s the frame – or lack thereof. The forward part of the frame is non-existent and the job is instead done by making the engine a structural part of the bike.

It looks great, but there’s nothing to stop the engine from taking a direct hit from a log or ledge, so a bashplate is a necessity. It’s packing a fairly healthy 396mm of ground clearance, however, which compares well to the current king of the big bores, the KTM 530 EXC-R, which has 380mm.

4. Husqvarna Tx 300cc

The Husqvarna TX 3oocc stroke features off-road capabilities, it’s fast, light and modern. Its engine’s shaft organisation is designed to centralize oscillating mass while a counterbalance shaft decreases vibration.

The engine is an electric starter for protection. To keep up with the compact design of the engine, the Li-Ion battery used is 2.2 pounds lighter than a standard battery. A 6-speed wide-ratio gearbox well complements the off-road design of the bike. Another commendable feature of the TX 300 is the 38mm Mikuni TMX carburettor that offers smooth delivery over the entire RMP range. The bike’s maximum speed is 112mph (180 km/h).

5. Honda XR 650l

Honda’s XR 650L line soldiers on, despite having little changes done since it was introduced in 1993. The Honda XR stays capable multiple years on to be one of the most reputed dual-sport bikes in the market. The bike’s air-cooled 650cc engine produces about 40 horsepower and a maximum speed of 110 mph (177 km/h).

The suspension is as capable as it was when the bike was first rolled out, and you also get colossal ground clearance and suitable off-road tires. Despite these decades-old components, the bike holds out its own on trails, city streets, and dirt roads.

The XR650L is a dual-sport motorcycle manufactured by Honda, part of the Honda XR series. The bike was released in 1992 as a 1993 model. It combines the RFVC engine from the proven NX650 Dominator dual sport with the lighter, off-road capable XR600R chassis, which is not road legal in the US (the XR600R). This bike has been produced virtually unchanged since 1993 and is still in production as of 2022.

6. MuZ Baghira 660cc

The Mz Baghira is a dual-purpose offering with a premium build quality. The first thing to note about this bike is that the seat is very tall. The 930mm seat height provides the required suspension travel and ground clearance to negotiate your way through dirt roads. You can comfortably ride the bike in the standup position because of the wide handlebars and footpegs.

The bike’s power is contained in the four-stroke Yamaha 650cc engine that produces 37 horsepower at 6,500 RPM. You can breeze to speeds of 102 mph (164 km/h) with a bike that can handle all kinds of terrain. The five-valve cylinder head is arranged in a Dual Overhead Cam setup with a 9.2 compression ratio. The engine also features water cooling, an electric starter, and a counterbalancer.

The MuZ Baghira is fitted with large Grimeca brakes. The rear wheel is equipped with a 9.65-inch hydraulic disc brake while the front has an 11.1-inch single hydraulic disc brake. The bike’s capable suspension system can handle rocks and stumps just as well as it can ride on asphalt. The bike can handle two passengers, and it is ideal for exploring the mountainsides over the weekend.

7. Husqvarna FE 501

The Husqvarna FE 501 is a reputed and competitive segment in the motorcycle community. It will suit off-road enthusiasts who want a serious machine with impressive engine performance. The 510- cc engine may weigh only 29.4 kg, but it provides formidable performance in any terrain. It features a standard electric start, electronic rider functions like traction control, and a 6-speed wide ratio gearbox. Users can easily finetune the bike to fit their skill levels.

The gearbox encourages smooth and accurate shifting while the gear lever’s design prevents dirt buildup. The bike is packed with advanced technologies to improve rideability. The Dampened Diaphragm Steel (DDS) clutch, for example, makes the clutch pull quite light. You can also enjoy more traction and durability thanks to the model’s integrated damping system.

The Husqvarna FE 501 can reach maximum speeds of 101 mph (163km/h). iIs acceleration times are also remarkable at 0-60 miles in 4.5 seconds and a peak horsepower of 58.

It has a single cylinder and an engine displacement of 651cc with a 40mm throttle body. This bike reaches the dry weight of 456 pounds and is definitely a heavyweight. Over the last few years, we’ve seen an improvement in the features of this bike, which continue to make it a superstar on the streets and on rugged terrains.

At 432 pounds, the Kawasaki KLR is quite heavy with a horsepower of 42. The instrumentation on the bike is not fancy, and the orange gauge needles bring about a 1980s-style nostalgia. The throttle is stiff and mechanical, and it has square indicator lights. Users can easily view the gauge displays since they are suitably placed above the bars. The fender will prevent dirt from flying to your face, and the plastic fairing is solid.

A 651 cc four-stroke engine powers the bike, and it can top speeds of 98 mph. It will fire on the first try thanks to the bike’s reliable capacitor-discharge (CDI) ignition system.

9. KTM SX-F 350cc

The 2019 model features a lightweight 350 cc engine with a maximum rpm range of 13, 400 rpm. The engine’s 57hp power output will propel you to a maximum speed of 98 mph. The bike also includes a sophisticated Keihin engine management system for extra user-friendliness. The engine recovery time for the bike is less than that of the 2019 model, and it also requires a little less clutch work.

The bike’s rigid frame helps it to stay on a straight light on the throttle, and its rear end remains connected to the road even when accelerating out of extended sweepers. Transmission is also incredibly smooth thanks to the Pankl, and you only need to perform an upward or downward motion with your foot.

KTM made significant changes to the bike’s suspension settings in 2020, and users can easily set up the model to suit their riding ability and style.
