The Sport model that was renewed in 1970, received a further update in 1975 with the addition of electronic ignition.
The aesthetics were profoundly redesigned and resembled the “350 Ipotesi”.
Among the details inspired by the “350” were the square crank and the cooling fins on the cylinder.
The aggressive colour scheme combined red and silver bodywork with a black exhaust.
The front disc brake was notable, and to underline the sporty nature of the bike, a version with full fairing was also produced.
