In my opinion, crf 150 is one of the most ridiculous inventions in motocross. Pretty much everyone says that running one is at least as expensive as running a 250f, and I for sure bet that 100cc two stroke, and even 85cc will straight up beat 150 four stroke in every conditions. JUST CMON FACTORIES, 2 STROKES IS WHAT PEOPLE WANT! We may still be little in the "minority" side, mut I bet most of the pro racers think 2 strokes are still cool and would race one IF the rules wouldn't pretty much kill those things.
