Puch 250 Moto-Cross

Here's a two page flyer for a bike I had hitherto not known the existence of, Puch's 250cc Moto-Cross. I am not sure of the exact year but it is circa 1965. Puch were unusual, but not unique, in sticking with the split single 'twingle' two stroke engine format for a number of years. The advantage was greater efficiency and torque but with a trade off against expense, complication and friction. Ultimately disc valves and reed valves gave greater benefit, cheaper. Puch made their twingles from 1953 to 1970, in the States they were marketed as 'Sears Allstates' and this model was marketed as the 'Scrambler'.
