Here is one more hint for this trivia...It seems this is a hard one
The company that produced this bike a long time ago, 47 years ago to be exact, is Japanese as I already mentioned in an earlier post, and is still in business! But it's not producing motorcycles anymore...
Another thing is that this bike is really very small in size, it looks to be normal size because the owner standing next to it, a really nice guy, is small as well
Alright. I'm about to give up. The closest that I have found (and I know it's not the same bike) is this, Its a TOHATSU (See? Contains an "H" ) PK54. The logo doesn't look the same but the bikes do look similar and the time period is right. I don't know much about outboard motors but I know that Tohatsu does makes them.
