| i have both the 6-port bizeta top-end and polini 5port on rep cases.
The BZM has a much flatter power delivery, and is easier to ride. It has a vast midrange.
The Polini 5-port 50cc is peakier. It makes all its power up top, revs a little harder. Great fun to ride, but not as easy to ride.
If you want something that will be consistent, good on twistier tracks and is easier to ride, go the Bizeta kit.
If you want something to get the blood flowing and put a massive smile on your face go the polini. It is an experts engine, but with a very good rider, would outperform the bizeta (given that neither are modified)
