Except for the front disc brakes AND the mufflers, this one IMO looks like a modified 1971 edition: new gaiter-less forks, chrome guards, no oil cooler covers , what looks like the so-called "conical" rear drum brake, two-tone side panels and fully exposed shock springs. BTW, the 1969 vintage gas tank remained std on the European version until the end of 1971.
By way of contrast, the original 1971 edition had a twin leading shoe "conical" front brake and more conventional mufflers with a long megaphone shape.
