A trials motorcycle is a specialized bike designed for motorcycle trials, a sport where riders navigate through an obstacle course without setting their feet on the ground, known as taking “dabs.” Unlike standard motorcycles, trials bikes are lightweight, have a small fuel tank, and lack a seat, emphasizing the rider’s need for balance and control. They feature a strong frame, high ground clearance, and are built to maximize maneuverability and torque instead of speed.
Manufacturers like Sherco, Beta, Montesa, Scorpa, OSET, Gas Gas, TRS, Vertigo, and Honda produce these motorcycles, often incorporating materials such as titanium to reduce weight. The design fosters precise throttle control, enabling the bike to respond to the subtle input necessary during a trial. In observed trials, an event overseen by the Federation Internationale de Motocyclisme, competitors are scored based on their ability to navigate sections without faults.
In addition to solo trials, there are sidecar trials where bikes, modified to include a sidecar, add a cooperative dimension to the sport. These mototrials require synchronized teamwork for riders to overcome natural terrain features. Spanish manufacturers have a robust history with trials motorcycles, with riders like the legendary Sammy Miller advancing the sport significantly. Trials bikes in the United States and other countries continue to evolve as manufacturers innovate parts and designs to improve the riding experience.
