A: The KTM 450 SX-F is currently the fastest 4 stroke dirt bike on the market. It’s also the fastest dirt bike you can buy in general. Few dirt bikes can measure up to the top speed of this dirt bike, which boasts a heady maximum speed of 123 miles per hour.

Typically a better bike for beginners, a four-stroke engine is great for both trail riding and racing. When trail riding on a four-stroke, you’ll rarely ride above second gear, because they can rev higher than a two-stroke can. This means less work for you and your engine.

If you are a pro at dirt bike riding and you want to experience real power while riding, then get a 250cc dirt bike. 250cc dirt bike delivers powerful acceleration with high performance. Depending on the type of engine, a 250cc dirt bike comes at a maximum speed of between 55 to 70 mph (90-113 km/h).

FIRST PLACE: KAWASAKI KX450 In the end, we weren’t especially surprised that the Kawasaki KX450 emerged as the top pick. It was our favorite 450 motocrosser in 2020 and it only got better. It still handles predictably, it still has excellent suspension and it still has a sweet power delivery that anyone can appreciate.

So, this 4-stroke dirt bike is a fantastic choice for dirt racing. Other fast 250cc four-stroke dirt bikes by Yamaha include the Yamaha YZ250F and the Yamaha WR250F. Both of these dirt bikes can hit a top speed of 70mph under favorable riding conditions.

Registered. My friend has a 750 and 90 mph is max speed on it.

Because 2-stroke engines are designed to run at a higher RPM, they also tend to wear out faster; a 4-stroke engine is generally more durable. That being said, 2-stroke engines are more powerful. Two-stroke engines are a much simpler design, making them easier to fix.

Best of all, IF you do keep up with basic maintenance, I’ve found my KTM and many of my riding buddy’s KTMs to be very very reliable. I’m 100% trail, no racing, so I don’t stress the motor with prolonged high RPM riding like some.

While max speed will vary slightly based on the type of engine, a 250cc dirt bike will come in between 70-78 miles per hour.

For weekend warriors and beginners, a newer 250-cc 2-stroke offers the ridability of most 4-strokes, minus some torque. Plus, they’re less expensive to maintain. A 250-cc 4-stroke is also a great option since it’s less expensive, lighter and easier to ride for a beginner.
