The Honda MT125R was a production Grand Prix motorcycle racing roadracer designed for closed-course competition roadracing. It was produced by Honda Racing Service Center (RSC) and made available to the general public. It was also marketed for the U.S. market in the years 1977–1978 through the American Honda Motorcycle dealer network and in Canada through Canadian Honda Motors Ltd., (later Honda Canada Inc.)

For many champion motorcycle roadracers, the road to the top started on a small engine capacity two-cycle motorcycle. Top roadracers like Randy Mamola got their start on a 125 cc GP racer. Others like Ángel Nieto spent their entire careers racing in the 50 cc, 80 cc and 125 cc classes.
