The Kawasakui G31M (Centurian) was a 100cc off-road motorcycle manufactured by Kawasaki from 1970 through 1971. In the early 1970s the highly tuned G31M was a dominate force in Flat Track, Tourist Trophy and some motocross racing along with its larger brother the 250cc Kawasaki F21M. This model consistently dominated the 100cc class with its unheard of 18.5 horsepower rated engine. The small tip on the expansion chamber gave the Centurion a distinct sound that is unmistakable to this day. Only 4490 units were made in 1970.
