CAUTION

• Do not disassemble the rear wheel hub assembly.
• The vehicle speed detection magnetic encoder collects any metallic particle easily, because it is

magnetised.Make sure that the magnetic encoder should not collect any metallic particle. Check
that there is not any trouble prior to reassembling it.

• When the rear wheel hub assembly is removed and installed, make sure that the vehicle speed

detection magnetic encoder does not contact with surrounding parts to avoid damage.

• When the rear wheel speed sensor is removed and installed, make sure that its pole piece does

not contact with surrounding parts to avoid damage.
