ECA22950 LIF
The lift control system reduces the rate
at which the front wheel will continue to
rise during extreme acceleration, such
as during starts or out-of-corner exits.
When front-wheel lift is detected, en-
gine power is regulated to slow
front-wheel lift while still providing good
acceleration.

suspension damping. The system is
controlled by the SCU which makes in-
dependent adjustments of both the
front and rear suspension's compres-
sion stroke and rebound stroke damp-
ing forces. There are two modes,
automatic and manual. Automatic
mode is an active suspension control
system which actively adjusts suspen-
sion damping forces based on running
conditions. Manual mode is a finely-tu-
neable traditional suspension set-up.
