The MAC was the 349 cc overhead-valve single that Velocette made by lengthening the stroke of the MOV. By 1959 it had the post-war swinging-arm chassis and telescopic forks and was a quiet, practical machine, overshadowed by the sporting Venom and Viper. It was among the last of the traditional high-camshaft Velocette roadsters before the MSS and Venom took over.
