What is the top speed of a dirt bike?

A Dirt Bike's top speed can vary depending on factors such as its engine size, weight, and terrain. Generally, most dirt bikes have top speeds ranging from 55 to 85 miles per hour (88 to 137 kilometers per hour). However, there are high-performance dirt bikes designed for professional racing that can reach speeds of over 100 miles per hour (160 kilometers per hour). It's important to note that riders should always follow LOCAL traffic laws and ride at safe speeds based on their skill level and the conditions of the trail or track.
