Next (4) is the YF1A (Jun. '65), the YF1 got new telescopic forks. (5) is the YJ1 (60 cc) of May '64 and (6) the YJ2 (Jun. '65) where it got also telescopic forks and "Autolube". (7) is the H1 (May '65) A 90 cc model joined the family. With a different tankshape from the YG1 it was more similar with the YA6 (125 cc) and YDS (250 cc). (8) is the YK80 (Sep. '66) A direct evolution of the YG series with H1 type tank. (9) is the YP1 of Mar. '65, a sporty model with the same type "T" backbone-frame. The 50 cc engine had 6 hp and the semi upswept exhaust, sporty shockabsorbers and other details made it a nice little machine. Picture (10) is the YGS1, a very sporty variant in the series with a very healthy 8,8 hp engine.
