Would like to know who was behind the two strokes expension chambers? or did you know already? Fortnine seems to have that story!

It's a fairly well known story, but Ryan makes it interesting.

I only got half way through that. Two mates of mine in Melbourne had RG 500s. Both rode hard, and neither of them died.

Could have stuck to history without the political commentary, but fundamentally good. 

Oh, and "The engines are identical" is at best misleading, and at worst, well, misrepresentation. Anybody who's ridden one knows it's not 170 horsepower, doesn't come on like a light switch- in fact, the powerband is much less abrupt than a Kawasaki Triple. Even if every part number in the engine is the same, the pipes and the porting make all the meaningful difference. On most 2-strokes, an hour by a professional and a tailored pipe can add 10-50% to any 2-stroke, depending on era and state of tune.

Well, I had never dug into where those expansion chambers came about. All I know, is that I had a Gitane Testi when I was 14 years old, and I purchased the expansion chamber sold by Motori Minarelli for my 49.9cc engine.

I knew the reason and the principle about it, but I never imagined it came from Germany.

The interesting part came towards the end of the video, and has nothing to do with the RG 500.
