New built AYK Boost with TWO SPEED ( A real story behind AYK Two Speed )
As far as I remembered, I saw Mr. Mok ( AYK H.K.dealer & shop 's owner since 80's ) in his shop who was holding a PB Mini Mustang Two Speed system & chat with someone......
He said ' We could make a copy from this PB Two Speed system , then we will have our own AYK Two Speed with better plastic than this , let's make a call to Japan AYK......' Then after a few months, AYK Maverick ( with Two Speed ) was produced !
