If my memory serves me correctly, back in the early 70's following the unveiling of the Kawasaki 900 monster bike of it's time, federal legislation was introduced to limit horsepower-to-weight ratio on all motorcycles. Luckily the AMA & every single manufacturer was all over it and beat the proposed legislation.
Now moving forward to our time of WoT, WoD, no-knock raids, helmet law changes nationwide, motorcycling enthusiam, TV shows, massive weeklong bikefests, etc. etc. etc., are we in for another round of restrictive laws aimed at the 200+ mph crowd?
The only other consideration that is an accepted norm is that cage drivers have little to fear from a 500lb motorcycle and driver. But the hazmat scrape and removal teams are staying busy cleaning flesh, blood and fuel spills after a high speed crotch rocket squish. At triple digit speeds the only thing a helmet does is crack like an egg and retain DNA samples.
Perhaps they'll bring back the Saint Joan of Claybrook (the DOT head under the Carter administration that brought us the "Backwards Bike") federally mandated 85mph speedometers!
