4 strokes ruled Baja back in the day also. Ad from May 1970 Cycle Mag. 1969 Baja Race - 1st Ducati 350 Scrambler - D. Douglas / J. McClerk. Ducati Desmo with race tested desmodromic valve mechanism. Below is 450cc model. Ad says also available with "Scrambler" type fuel tank on 250cc and 350cc models. Love all the old bikes, the style and nostalgia. Looking forward to owning a cool old ride one day myself.
