why doesnt ama or any of the motorcycle racing industries, you know the ones you see on tv, have any naked bike classes. i dont know bout any of you but i would like to see some naked bike races

marketing mostly.  The factories want to sell you the latest and greatest bike, and they all have fairings.

Its also a almost Darwinian thing.  Fairings work, so those with them go faster, win races, which sell more bikes, and so see the above point.

AHRMA has several classes for "naked" bikes.

well yea i see your point but why not do that same thing for bike without all the extra plastic? you know find the best out of that category

Those were the old days of racing without all that bodywork... The closest years of racing like that, that I can remember, are when Wes Cooley, Keith Code, Eddie Lawson and Freddie Spencer were racing in the Superbike Series in the '80's. Times have changed, modern machinery race with billboards attached to them. Seems that that is the only way to obtain sponsorship is if you have bodywork to advertise their name.

AMA does so have naked roadracing machines.  They're called Supermotos!
