GENERAL INFORMATION
M1321000100340
The engine mounting system employs the inertial
axis four-point suspension method, which is field
proven.
•The optimised locations of the front and rear roll
mounts well distribute their loads thereby reduc
-
ing engine idling vibrations.
•The fore-and-aft, liquid-filled engine mount of cyl-
inder type is adopted to reduce engine shake for
improved riding comfort.
