Dirt bikes and street bikes have different specs- that is, dirt bikes are equipped with aggressive and knobby tires that offer great traction off-road.
Street bikes are equipped with slick tires that make it easier to control during highway riding
A dirt bike is also known as a motocross bike. It's lighter and less bulky than a street bike, and was specifically designed for riding off-road.
It is important for a vehicle to be sturdy enough to withstand the pressure of the road. This ensures you can hold on to your bike effectively. For this reason street bikes are designed with a sturdy frame and strong build.
The tread pattern of street tires can deflect water that may get stuck in the tire's design.
