I would take a 2 stroke over a 4 stroke any day, My first 2 bikes were 4 strokes, then I started riding 2 strokes and never looked back...Well I think the fact the 2 stroke won’t overheat as fast, has smoother /better power delivery and light weight is what drove the revolution- If you go to an Enduro and look at the starting line it will just be a sea of orange and white (husky/ktm makes them too) bikes.
This started around 07-08- the Japanese abandoned 2 strokes At the same time the Austrians perfected theirs-
This is not to say that four strokes are not viable - But to get the same power they had to up displacement of the four stroke and they became monsters- There are still a lot of people that love both, But when you start looking at guys doing slower , tight trail riding you’re going to see a lot more two strokes overall.
A big thumper is still fun-that is the word for a 4 stroke.
Like you said, KTM and Husky have pretty much perfected 2 strokes
