Warning
When ABS is disabled, the motorcycle restores
the standard brake system features; using the two
brake controls separately reduces the motorcycle
braking efficiency. Never use the brake controls
harshly or suddenly as you may lock the wheels and
lose control of the motorcycle. When riding in the rain
or on slippery 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 tyres reduce
braking efficiency, handling accuracy and stability in
a bend.
