Removal
1 Place the machine on an auxiliary stand.
Position a support under the rear wheel so that it
does not drop when the shock absorber lower
mounting bolt is removed, but also making sure
that the weight of the machine is off the rear

2 Remove the seat (see Chapter 8). If required
for improved clearance, also remove the exhaust
system (see Chapter 4). On XTZ models, where
fitted, remove the rubber boot from around the
shock absorber lower mounting.
