CONTROL FUNCTIONS
EASB111030ENGINE STOP SWITCH
The engine stop switch “1” is located on the left
handlebar. Continue pushing the engine stop
switch till the engine comes to a stop.
EASB111031LAUNCH CONTROL SWITCH
The launch control switch “1” is located on top
of the left handlebar.
When the launch control switch is pressed, the
ignition timing is delayed to reduce slipping at
the rear wheel which occurs when the vehicle
accelerates from a stationary position.
This can be used to starting off in a stable man-
ner on a slippery road surface.
However, the effect may not be adequate de-
pending on the rider’s operations and road sur-
face conditions.
How to operate
1. Put the gear into the neutral position.
2. Start the engine.
3. Push the launch control switch for more than
one second to turn on the launch control
switch.
TIP
When the launch control switch is turned on, in-
dicator “2” will flash.
4. Put the gear into the 1st or 2nd gear for start-
ing off.
5. After starting off, the launch control switch
will turn off automatically when the gear is
shifted into the 3rd gear.
The launch control switch will also turn off when
the engine is stopped or the gear is shifted into
the 3rd gear or higher.
TIP
When the launch control switch is turned off, in-
dicator will stop flashing.

TIP
Turn the handlebar toward right and left to
make sure that the brake hose does not touch
other parts (e.g., wire harness, cables, leads).

reservoir up to the specified level.
EWA13540
WARNING
• Use only the designated brake fluid. Other
brake fluids may cause the rubber seals to
deteriorate, causing leakage and poor
brake performance.
• Refill with the same type of brake fluid that
is already in the system. Mixing brake flu-
ids may result in a harmful chemical reac-
tion, leading to poor brake performance.
• When refilling, be careful that water does
not enter the brake master cylinder reser-
voir. Water will significantly lower the boil-
ing point of the brake fluid and could
cause vapor lock.
ECA13540
NOTICE
Brake fluid may damage painted surfaces
and plastic parts. Therefore, always clean
up any spilt brake fluid immediately.
