Would one rather have a Malossi T5 172cc with the 5 ports, or a Malossi 210 with a 3 port engine case? Question dives into ports vs displacement. Powerband with either setups?

I worked out...

150 = REVS
200 = TORQUE.

Revs is far more fun, unless you are heavy or live at the top of a big hill.

It depends. Ports, timings and displacement are parts of the equation. Gearing is also important.

My stock 200 with the 23/65 primary does higher speeds and stays cool. It feels heavy and cruisey. Shifting is really easy and forgiving.

My VMC 187 with 22/68 primary has a totally different feel. It's quicker and more responsive. Shifting requires more attention to keep the revs in the right place when downshifting. In some ways it's more fun to ride.
