Pit bike riders realized this and started moving their focuses to the KLX110. The KLX110 is bigger and faster than an CRF50 and has a greater top speed so it needs fewer parts to make it comfortable for bigger riders. This bike, as with Honda's XR50, was designed for smaller riders. In 2002, Kawasaki came out with the KLX110. As more and more people put these upgraded parts on their Z50's their popularity grew and lead to pit bike races across the United States. Some of these parts include heavy duty suspension, tall handle bars, tall seats, and big bore kits. As teenagers and young adults began to show interest in Z50's, companies started to be formed which make upgraded aftermarket parts for pit bikes that make them comfortable and powerful for bigger riders. A few of these changes include a plastic gas tank, single rear shock, spoke wheels, seat, plastics, total redesign of the frame, and the total appearance of the bike. By the time the trend caught, Honda had changed the name from Z50 to XR50 in 1999 and made great changes to the bike. The fairly cheap price and the mobility of these bikes made them easy to use at racing events.

The name pit bike originated from the use of a Honda Z50 to ride around the pit areas of dirt bike races and race events across the United States. Since the early 2000s pit bike racing, a sport similar to motocross, has become popular in the United States, especially in Southern California. A pit bike is a small off-road/on-road motorcycle originally used for riding around the pits or staging area of a motocross race.
