Mototrials, formerly called observed trials, is a unique subset of the off-road realm that focuses on overcoming insane obstacles with a combination of balance, finesse and strategy. Horsepower isn’t discussed among trials guys; they're all about torque and traction. The bikes typically weigh about 150 lbs.—the same as a two-stroke 85cc mini-motocrosser. The biggest difference between a mototrials bike and other motorcycles is riding style. You don’t sit, and you should _never _put a foot down.
