Maybe it's well known already, but it seems as though the four-stroke agenda (tm?) is hitting the road racing world too.
Caught this blurb when looking over a race bike overview:
"With the four-stroke Moto3 class to replaced the current two-stroke 125cc Class in FIM Grand Prix racing, Honda will release the 2012 Honda Racing Corporation (HRC) NSF250R in America.
...
The NSF 250 R features a liquid-cooled, single-cylinder 249cc four-stroke engine that will be legal in USGPRU Moto3 and WERA racing in the USA, and others."
...
To twist the knife further... I quote HRCA:
"Just as off-road riders can purchase and race one of our full-on CRF450R or CRF250R motocross bikes, now road racers have the means to buy a race-ready track bike."
The price: $28,600 USD. 28K is Ducati 'S' teritory. What's a good Yamaha TZ or Honda RS or Aprilia RS worth? A lot less!
