in 1968 released by YAMAHA corporation.
Currently, the two stroke engine being persecuted all over the world because of the environmental
pollution issue.
But at that time, most small motorcycle have two stroke engine because two stroke engine give us good power and good feeling than four cycle one.
AS-1 is first YAMAHA machine which have 125cc twin engine.
Two 43mm diameter pistons output maximum 15 horse power and 130km/h.
This is very exciting specification !
Shrill exhaust sound and smoke also very exciting !
Unfortunately, 125cc class motorcycle changed to single piston model for manufacturing cost.
But I love such kind of motorcycle which have two stroke twin engine and I call LITTLE TWIN.
I would like to support two stroke machine.
