Bidalot C20

[Speed Fury]

Hey Forum

I was wondering:

In wich area (rpm) does the c20 work? Í have heard from some friends its around 13,500 - 14,000. Is this correct?

Im asking this question because I might gonnar order it for my Piaggio Zip!

Approximately this data is correct, but the expansion chamber's operating rpm depends from the exhaust port's duration!

Okay!

Thanks for the answer
