Kinda hard to figure it out, but it looks as though the next generation Honda was the 1951 E type.
This bike is the first to be exported, with demand so great they struggled to produce 160 units a day.
First improvement one sees is the rear
shocks, going from ridged frame and the motor,
from a single cylinder 2 stroke to a 150cc 4 stroke.
The clutch went from wet to dry, and when they added a 3rd gear sales hit 500 a month.
