Motorcycle trials
（重定向自Observed Trials）
Motorcycle trials, also known as observed trials, is a non-speed event on specialized motorcycles. The sport is most popular in the United Kingdom and Spain, though there are participants around the globe.
Modern trials motorcycles are distinctive in that they have evolved to become extremely lightweight, lack seating (they are designed to be ridden standing up) and have suspension travel that is short, relative to a motocross or enduro motorcycle.
