    OK, I have been riding for quite awhile and have heard the terms Stage 1 Stage 2 Stage 3 etc...

    never really paid much attention nor did I ask about what it meant.

    Now I am wondering:

    What do these terms mean and where did it originate from?

    Also is there a website or link that details the different stages or am I to assume that this is all marketing hype and does not mean very much.

    Thanks to all replies and especially those that quote some sources for additional reading.
