American Honda has released information on the first of its planned 2011 rollouts. As is usually the case this early in the cycle, the first bikes announced are dirtbikes. Topping the list is a new CRF450R, which received updates to the engine to broaden its powerband with more bottom- to midrange power. Additionally, a new throttle body is used for improved engine response. A redesigned muffler has a quieter 94-dB sound rating, which is required by various racing organizations. Tweaks were made to suspension for improved ride quality and better rear-wheel traction. The CRF450R will be available in October for $8199.
