GENERAL DESCRIPTION

M1321000100373

• The engine front mounting bracket is a 

dome-shaped fluid-filled mount for improved 
responsiveness during acceleration and more 
stable vehicle performance against road distur-
bances.

• The liquid-filled transaxle mounting body side 

bracket improves riding comfort by its refined 
insulator.

• A roll stopper bracket in the upper area limits 

engine rolling. Furthermore, large diameter insu-
lator reduces idle vibration.
