GENERAL
SYSTEM DESCRIPTION
(FEATURES)
The Dynamic Power Steering (DPS) provides
a computer controlled, variable power assist,
achieved by an electric motor to optimize the
amount of steering input required by the rider.

1. Dynamic power steering unit (DPS)
The DPS system uses the following parameters to
determine how much steering assist it provides:
– Engine RPM
– Battery/electrical system voltage
– Vehicle speed
– DPS shaft torque sensor input.
The amount of steering assist provided is depen-
dent on the handlebar effort (steering torque),
electrical power available, and vehicle speed.

The greater the handlebar effort (torque), the
greater the assist will be.
The slower the vehicle speed, the greater the as-
sist will be.
If the electrical system is activated but the engine
is not running, there is no power assist provided.
When the handlebar is in the straight ahead posi-
tion, there is no steering assist.
Steering torque may also come from the wheels
due to rough terrain. Steering kickback is reduced
while providing feedback to the driver.
The greater the power steering assist, the greater
the load on the electrical system.
When the electrical system is under high load
(battery not at full charge, operating the vehicle
for prolonged periods of time at slow speed and
low RPM which, requires higher power steering
assist), the battery power reserve will gradually
decrease. This further increases the load on the
charging system and the electrical system volt-
age will drop. As system voltage drops, so does
power steering assist.
NOTE: It is important to maintain the battery at
a full state of charge to ensure proper DPS oper-
ation. The magneto output is 650 watts to mini-
mize battery drain and system voltage drop.

DPS Assist Mode

The DPS system provides three rider selectable
modes of operation.
DPS MAX provides maximum steering assist for
technical low speed riding in rough or muddy ter-
rain, or for touring.
