PISTONS
The pistons are made of a special aluminum alloy.
Their weight has been reduced by lowering their
overall height and increasing the depression at each
end of the piston pin.
The piston pin hole center is offset 0.8 mm (0.031 in)
towards the thrust side of the piston center.
The skirt portion along the perimeter of the piston is
finished with streaks that excel in oil retention and
seizure resistance.
PISTON PINS
The piston pins are the semi-floating type. Each pin
is press-fit and secured in the small end of the con
-
necting rod, while it floats in the piston.

•The seat frame and head restraint have been
installed to the proper positions to minimize the
severity of whiplash injury at rear-end collision at
a low speed. (Whiplash injury reduction seat
structure)
•The overall height mechanism raises and lowers
the seat cushion together with the seatback, thus
the driver's posture is always kept at the best
position, resulting in the improved riding comfort.
•The pump-type height lever has been adopted for
easier operation with a light force by the vertical
adjustment system. Also, the height adjustment
amount has been increased for more optimum
driving position.
•The variable hardness pad has been adopted for
the sporty-look seat with increased bucket
amount of side bolster in order to establish the
sporty shape with support function , and
the standard shape which is basic and for actual
use and comfortable driving.
•Heated seats are available for the driver's and
