Motorcycle Trials is a competitive sport where riders navigate through a series of obstacles on their motorcycles. The goal is to complete the course without putting a foot down or falling off the bike. Obstacles can include rocks, logs, and steep hills, testing the rider's balance, control, and skill. Riders are scored based on their performance, with penalties given for mistakes such as touching the ground or failing to clear an obstacle. Trials bikes are specially designed for this sport, featuring lightweight frames and powerful engines to help riders tackle challenging terrains effectively.
