Sorry but in follow up I had to post this also after checking out A J's website - its part of the description for his Service Honda CR250.. so funny!
"Terror, the reaction is unmistakable. Service Honda 250AF, say the name and watch the reaction of factory supported 250cc motocross race teams. When the AMA was considering making the 250AF legal for Pro Racing these race teams told the AMA ' if a Privateer team shows up on the 250AF we will not race'. No surprise that the factory supported race teams reacted this way, the 250AF is lighter, more nimble and more powerful than the competition.
Not only does the 250AF perform better than the 4 stroke competition it is vastly cheaper to maintain, cutting the TOTAL operating budget for a national outdoor motocross team by nearly one third!"
