(1968 / Production Model)
This sport model featured clean styling and coloring and was aimed at riders around 20 years of age. Based on the AT90 (released in 1965), it adopted the "Autolube" system and a twin-carburetor 90cc 2-cylinder engine with a 5-port layout to boost exhaust efficiency. It also featured a sporty return-type 5-speed transmission and a diamond frame of the same strength as a 125cc model in a package that achieved powerful performance with the lightest chassis in its class.
