The 1968 Meierdres special.
Dutchman Jan Meierdres bought the entire Tohatsu- teams 50cc racebikes, eight pieces all in all. These Japanese 50cc twins were rendered useless by the onset of the 1969 ruleset, so some of the engines were converted into singles. As you can see, the crankcases has been narrowed, and a DRM watercooled cylinder fitted.
