SUSPENSIONS
The connection points between the wheel riser and the levers are coated to exploit the available space inside the 16'
rims to the maximum with considerable benefits on lateral stiffness. The adoption of a very stiff hub has additionally
improved this stiffness.
Coaxial shock absorber spring unit with double tube shock absorber has increased size and now fits a 15 mm rod
and 32 mm valve unit. The oversized dimensions have increased the shock absorbing filtering capacity by also
reducing the hysteresis levels. The unit is connected to the body by a generously dimensioned split mount with a
high noise filtering capacity.
The aluminium lower swing arm combines excellent structural features to lower weight with respect to earlier
solutions. The main feature is the specialised bushings connected the arm to the chassis. The lower bushing is
extremely stiff and withstands most lateral and longitudinal loads, by opposing extremely low distortion with benefits
on loss of camber when cornering. The double sized hydraulic rear bushing is only responsible for providing the
suspension with an excellent longitudinal filtering capacity.
