A soft or spongy feeling in the
brake lever can indicate the
presence of air in the brake
system. This air must be
removed by bleeding the brake
system before the motorcycle
is operated. Air in the system
will cause greatly diminished
braking capability and can
result in loss of control and an
accident. Have a Yamaha
dealer inspect and bleed the
system if necessary.
