Document Type and Number:
Japanese Patent JP2009292358

A
Abstract:

To provide a motorcycle can restrain increase of unsprung weight when a dynamic damper is provided.

The dynamic damper is constructed by using mass and spring properties that existing components of a wheel 8, a brake device 9, and a wheel support member 10 possess, therefore, the unsprung weight can be reduced compared to the case for externally disposing a new dynamic damper where a conventional weight is built in, thus improving response to road surface vibration accordingly. The mass and the spring properties that at least one of components of the wheel 8, the brake device 9, and the wheel support member 10 possesses construct the dynamic damper 48 for absorbing the vibration of the wheel 8.
