We applied the following noise reduction technologies to the CBR 1000RR, introduced in Japan in February 2006, enabling us to improve the engine output while meeting the third noise regulation standards of Japan:

• Engine noise

To reduce radiation noise, sound insulating materials used in the cowl were replaced with lighter, more effective materials.

• Drive system

Urethane foam was injected into the interior of the drive system to reduce drive chain noise and radiation noise that are caused by vibrations of the engine and emanate through the surface of the swing arm.
