That's what they be brought up with and understand just as us "old guys" understand try Open bikes. Many think it's all about what's "fastest" not about the developed skill it take to ride an "Open" bike fast.
Don't get mad at people that don't understand. Perhaps an influx of emails from people wondering why we need a fixed displacement and not just a truly 'open' class to Vital MX is in order.
Constructive criticism is much better/effective them criticism ATMO.
