Some of it is cheaper brake systems and less magnesium components etc. I really don’t feel most karts on the market are 206 specific as much as the manufacturers threw together a kart with a straight rear bar to take advantage of the fastest growing karting market in North America. I’m very skeptical to think many of these manufacturers even tested their karts with a 206 before they started selling to the public. And the prices are lower because they know cheaper alternatives are out there, not because it actually costs that much less to produce. They are just go karts made of metal. How does one cost as much as 1500 less from the same company just because it has a different brake, axle, and wheels?
