I like the idea of a pro/cons of speedways thread. If i was going to do a poll, i would weigh 10" wheel versus 14" wheel speedways. I would not include the 2 stroke speedways. those are just damn rare, no very many people have seen one, much less rode one, much less own one.
On the Speedway vs japanese bikes... honda was underselling their mini bikes to capture the market. figuring if they could hook you at 12 years old, they would have a customer for life.
