I may be talking out of my "other end" but I seem to recall somewhere that Gilera started reducing the power of their 125 two-strokes as it was getting into a session of the young Italians would buy whichever bike was the quickest at that time. To me it makes no sense to deliberately reduce power if the sale of the bike depended on it being quicker. Maybe something was lost in translation, or maybe there was some technical reason, but I'm sure it was done for a reason.
