The swept back handlebar clamps are correct, the 1978 KX125 had straight upright mounts, they may have got the photos wrong in the manuals or possibly the preproduction prototype which they use for the photos for the manual may have had the 125 clamps - who knows. Also note on the preproduction KX250A4's which were given to the press for magazine testing in advance of the actual production bike launch had fins which ran all round the base of the forks below the axle, but the production bike had only token fins on the front section of the forks below the axle. They are great bikes, attention to detail which was comparable to that only seen on factory bikes at that time.
