Periodic Maintenance Procedures
Install the front forks to the motorcycle (see Front Fork
Installation in the Suspension chapter).
Loosen the front fork mounting bolts (upper).
After installing the front fork, tighten the top plug [A].
Special Tool - Top Plug Wrench, 49 mm [B]: 57001-1653
The torque of fork top plug is specified to 30 N·m (3.1
kgf·m, 22 ft·lb) however, when you use the top plug wrench
(special tool) [A], reduce the torque to 90% of the spec-
ified value [27 N·m (2.8 kgf·m, 20 ft·lb)] due to the dis-
tance [B] between the center of the square hole, where the
torque wrench is fitted, and that of the octagonal hole of the
This torque value [27 N·m (2.8 kgf·m, 20 ft·lb)] is appli-
cable when you use a torque wrench whose length gives
leverage of approximately 310 mm between the grip point
to the center of the coupling square.
Torque - Front Fork Top Plug: 30 N·m (3.1 kgf·m, 22 ft·lb)
Front Fork Clamp Bolts (Upper): 20 N·m (2.0
kgf·m, 15 ft·lb)
Install the removed parts (see appropriate chapters).
Adjust the compression and rebound dumping force ad-
justers (see Compression Damping Adjustment and Re-
bound Damping Adjustment in the Suspension chapter).
Number Plate (see Number Plate Removal in the Frame
Front Wheel (see Front Wheel Removal in the
Air Valve Plug [A]
Bleed air by pushing down the air valve.
Do not compress the inner tube.
Loosen the front fork clamp bolts (upper) [A].
Set rebound and compression damping setting to the
softest settings before disassembly to minimize damp-
ing forces that can hinder disassembly. Record the set-
ting before turning the adjuster.
