Tighten the front fork top plug before tightening the han-
dlebar clamp bolt and upper front fork clamp bolt.
The torque of front fork top plug is specified to 35 N·m
(3.6 kgf·m, 26 ft·lb) however, when you use the top
plug wrench (special tool: 57001-1741) [A], reduce the
torque to 90% of the specified value [31 N·m (3.2 kgf·m,
23 ft·lb)] due to the distance [B] between the center of
the square hole, where the torque wrench is fitted, and
that of the octagonal hole of the wrench.
This torque value [31 N·m (3.2 kgf·m, 23 ft·lb)] is ap-
plicable when you use a torque wrench whose length
[C] gives leverage of approximately 310 mm (12.2 in.)
between the grip point [D] to the center of the coupling
To obtain the correct tightening torque with your torque
wrench, you need to calculate as follows.
a × b ÷ (b + c) = d
[a] Specified torque
[b] Length from center of square hole to grip point
[c] Offset = 44 mm
[d] Tightening torque
For an example:
35 N·m × 310 ÷ (310 + 44) = 31 N·m
Install the fork so that the top end [A] of the outer tube as
9 mm (0.35 in.) [B]
Steering Stem Head [C]
Torque - Lower Front Fork Clamp Bolts: 23 N·m (2.3 kgf·m,
Tighten the two lower front fork clamp bolts alternately
two times to ensure even tightening torque.
Torque - Upper Front Fork Clamp Bolts: 20 N·m (2.0 kgf·m,
Install the removed parts (see appropriate chapters).
