    I have to agree with this. They are waay more flexible than 4 strokes. BUT most people want torque, high rpm and high speed on small cc bikes WITH managable riding, without any difficulties or liftime problems. Sadly that is not really possible. I'm speaking the under 100cc class. On higher cc's its more possible. Altough High tourque and high RPMs are not really easy to port. They dont really like each other.

    For some info, I saw a guy on some Facebook group make a 2t bike with 2 clinders, one was ported for high rpms, one was ported for low rpm high torque. On low rpm only the low rpm cylinder worked. On high rpm only the high rpm one worked. If I remember correctly he made a custom cdi for it and a mechanical weird stuff what disconnected the other crankshaft so just 1 cylinder was spinning. It was fucking interesting. Sadly he ran out of money and wasnt been started up. Someone bought it, now we dont know anything about it

    Sounds like an interesting project to read about, but not one that I'd actually want to install on any of my bikes.
