For motorcycles meant to deliver thrills off paved roads, reaching blistering high speeds may seem like an afterthought. Jumps, skids, and climbs excite most dirt bike riders enough. However, you have to arrive at the location first, so you might as well entertain yourself on the commute.

Some of the best dirt bikes can manage speeds over 100 mph with the right rider, conditions, and level of bravery. Here are the 12 fastest dirt bikes in the world in the segment of supermoto and dual-sport bikes weighing less than 450 lbs.

10. Suzuki DR-Z400SM

  • Top speed: 94 mph

The DR-Z is a dual-sport classic. Like modern crossovers, a dual-sport is cross between a street bike and a dirt bike. But don’t let its appearance fool you. The Suzuki DR-Z400SM is a competent dirt bike. It tops out at a respectable 94 mph, with acceleration that is nothing to sneeze at. The bike can go from 0 to 60 mph in 4.54 seconds. The DR-Z needs an experienced rider who can handle it in messy conditions. But in the right hands, it’s a great bike.

9. Honda XR650L

  • Top speed: 98 mph

This is a tremendous all-around dual-sport bike from Honda, the XR650L offers speed and quality for a fair price. While not able to top 100 mph, this bike can still satisfy someone’s need for speed with a top speed of 98 mph. Its acceleration won’t blow you away, but it is still respectable, with the ability to reach 60 mph in 5.83 seconds. Don’t sleep on this classic. There’s a reason it’s been around for over 20 years.

8. Kawasaki KLR650

  • Top speed: 98 mph

Like a few other bikes on our list, the Kawasaki KLR 650 skews more to the street side, but its off-road capabilities are solid. The redesign between 2006 and 2008 earned rave reviews, and as competitors entered the scene, it remained an excellent value and is still a perennial best-seller.

In terms of speed, it can hit 98 mph in its fastest editions and still reach speeds in the mid-90s in later models. It hits 60 mph in 6.04 seconds.

7. Husqvarna FE 501 S

  • Top speed: 101.5 mph

With 58 hp from the 510cc engine, the 2016 Husqvarna FE 501 street model delivers plenty of power for anyone hunting for a dual-sport machine. Combined with the weight savings offered in this model, this bike can match the top speed of 650 editions from before the manufacturer’s KTM era.

The 501 dirt model broke 100 in informal testing. Street models will match the 101.5 mph once clocked on the TR650. Sprinting to 60 takes about 4.5 seconds.

6. MuZ Baghira

  • Top speed: 102 mph

Since its disappearance in 2007, the MuZ Baghira has endured as one of the classics of the dual-sport segment. For a bike considered more street than trail-worthy, it takes 5.22 seconds to hit 60 mph.

However, its power output sent it to impressive top speeds, once topping 102 mph in tests. Exhilaration on- and off-road was always Baghira’s most significant selling point, and those who can track one down used can get it cheap.

5. BMW G650 XChallenge

  • Top speed: 104 mph

When you think of BMW, you probably don’t envision ripping a dirt bike around trails. However, the BMW G650 XChallenge dirt bike can easily hang with other traditional bikes. Topping out at 104 mph, this bike has all the power you’d expect from BMW. This bike is perfect if you’re looking to keep it classy in the trials.

4. ATK Intimidator

  • Top speed: 110 mph

Whether packing the Maico 620 or 700 engine, the limited edition ATK Intimidator has long been in the running for the fastest dirt bike in the world. The 700 houses a 685cc two-stroke engine capable of 78 hp for a bike with a dry weight of just 238 pounds. Compared to the fastest dirt bikes tested, an ATK Intimidator would have a clear edge with the proper modifications. Racers have pushed the 700 Intimidator to speeds over 110 mph.

3. Beta 450RS

  • Top speed: 110.9 mph

You’d be surprised to learn that this sleek dirt bike is street legal in the United States. Beta might not be a familiar company to many people in the U.S., but this bike makes a name for itself. With a top speed of almost 111 mph, it has more speed than you could ever want. If you want a fast bike that can rip around trails but also cruise down the road, you can’t go wrong with the Beta 450RS.

2. Aprilia RXV 5.5

  • Top speed: 113 mph

At 303 pounds, the Aprilia RXV 5.5 is a heavy bike that rides light. Most of this weight can be attributed to the 549cc engine, which puts out 55 hp. This bike topped 100 mph with ease, getting up to 113 mph.

Its weight didn’t hamper the bike’s acceleration either, as it could get from 0 to 60 in 4.16 seconds. While this bike comes in heavier models that offer a little more power, in terms of bang for your buck, the RXV 5.5 is your best bet.

1. KTM 450 SX-F

  • Top speed: 123 mph

KTM always produced bikes challenging the fastest two-wheeler on the planet. The 450 SX-F was a Motocross Champion under rider Ryan Dungey in the dirt bike category.

The 449cc engine is used to power a bike weighing just 237 pounds. KTM 450 bikes will win races among any sprinting dirt bikes with the right rider. With a top speed of 123 mph, nothing under 450 pounds can compare, so feel free to “drop the hammer.”
