Factors Determining How Fast a Razor Dirt Bike Goes

A Razor dirt bike ‘s top speed essentially depends on the five factors listed here.

1. Motor Size

Razor dirt bikes like many other dirt bikes depend on the motor size to attain top speed. Bigger motors often lead to faster speeds and can sometimes extend run time by a few minutes.

For instance, a 250w dirt bike may reach a top speed of 14 mph. But, you may be able to expect a top speed of 17 mph from a 500w Razor dirt bike.

Interestingly, larger-sized dirt bikes not only go faster, but they have a longer battery life. For example, while 250-watt dirt bikes have a 30-35 minute run time, 500-watt and 650-watt razor dirt bikes reach an average of 40-50 minutes on a full charge.

The following table here illustrates the motor size differences among the Razor dirt bikes.

Razor Dirt Bike Motor Size Top Speed (mph) Top speed (kph) Runtime 
250w 14mph 22.5kph 30 – 35 min
350w 14mph 22.5kph 30 – 35 min
500w 15mph 24kph 40 min
650w 15–17mph 24-27kph 40 – 50 min

2. Rider’s Weight

Every Razor dirt bike has a maximum weight restriction. You mustn’t exceed the limit, but you should be careful not to be so light that you don’t know how to control the bike.

3. Terrain

Razor dirt bikes come in MX and SX Motocross (MX and SX) and Street Racing (RSF) choices to match varying surfaces. A Razor MX or SX dirt bike will start until it reaches its top speeds on dirt and racing tracks, and a Razor RSF can be used in the streets.

When you find a racing bike that’s straight for your terrain, you’ll be satisfied with it. For example, the Razor MX350 (available on Amazon) will accelerate up to fourteen miles per hour on dirt tracks and motocross courses.

Get yourself a Razor RSF350 (view on Amazon) to excel at such speed on the road. Likewise, you can’t do 14 mph off-road using an RSF350 as using an MX350.

4. Runtime

One essential thing to not forget is that the duration of race output can determine how long a Razor dirt bike can run at top speed. None of the Razor electric dirt bikes can run for more than 50 minutes on one charge.

Note that these dirt bikes will not go at a constant top speed for 30 to 50 minutes. They will hit maximum speed for approximately half the time.

5. Range

Let’s now turn our attention to travel range (distance traveled). Generally, more powerful engines (larger motors) have a greater travel distance to match their high speed.

The less time it takes you to go, the shorter the runtime and the time to travel. So, you won’t be able to travel at the fastest speed possible.
