Attention
Although combined braking is available (rear
brake activation when rider uses only the front
brake), using the two brake controls separately
reduces the motorcycle braking power.
Never use the brake controls harshly or suddenly as
you may cause rear wheel lift-up and lose control of
the motorcycle.
When riding in the rain or on low-grip surfaces,
braking will become less effective. Always use the
brakes very gently and carefully when riding under
these conditions. Any sudden manoeuvres may lead
to loss of control. When tackling long, high-gradient
downhill road tracts, shift down gears to use engine
braking. Apply one brake at a time and use brakes
sparingly. Keeping the brakes applied all the time
would cause the friction material to overheat and
reduce braking power dangerously. Underinflated
and overinflated tyres reduce braking efficiency,
handling accuracy and stability in a bend.
Note
Emergency braking
In the event of heavy braking from a speed of more
than 55 km/h the tail light flashes rapidly in order to
warn the vehicles behind. When deceleration is
reduced below a predefined threshold, the flashing
is automatically deactivated.
