Turn the spring preload adjuster [A] counterclockwise until the fully position.
Unscrew the top plug [B] out of the inner tube.
Holding the piston rod nut [A] with a wrench [B], remove the fork top plug from the piston rod.
Remove:
- Rebound Damping Adjuster Rod [A]
- Washer [B]
- Spacer [C]
- Washer [A]
- Fork Spring [B]
Drain the fork oil into a suitable container.
Pump the piston rod [A] up and down at least ten times to expel the oil from the fork.
Hold the fork tube upright, press the inner tube and the piston rod all the way down.
Pour in the type and amount of fork oil specified.
Fork oil:
- Viscosity: SAE 10W
- Amount (per side):
- When changing oil: approx. 456 mL
- After disassembly and completely dry: 537±4 mL
★ If necessary, measure the oil level as follows.
Hold the outer tube vertically in a vise.
Pump the inner tube several times to expel air bubbles.
Using the piston rod puller [A], move the piston rod up and down more than ten times in order to expel all the air from the fork oil.

Wait until the oil level settles.
With the fork fully compressed and the piston rod fully pushed in, insert a tape measure or rod into the inner tube, and measure the distance from the top of the inner tube to the oil.
Oil level (fully compressed, without spring):
Standard: 116±2 mm (from the top of the inner tube)
Note. Fork oil lever may also be measured using the fork oil level gauge.
Special Tool - Fork Oil Level Gauge: 57001-1290 [A]
With the fork fully compressed and without fork spring, insert the gauge tube into the inner tube [B] and position the stopper across the top end of the inner tube.
Set the gauge stopper [C] so that its lower side shows the oil level distance specified [D].
Pull the handle slowly to pump out the excess oil until the oil no longer comes out
★ If no oil is pumped out, there is insufficient oil in the inner tube. Pour in enough oil, then pump out the excess oil as shown above.
Pull the piston rod [A] up above the inner tube top.
Screw the rod nut [B] on to the piston rod with the chamfered side [C] down.
Check that the visible thread length is at least 11 mm [D].
Insert the rebound damping adjuster rod into the piston rod.
Screw the fork piston rod puller onto the end of the rod.

Install the fork spring with the smaller end facing downward.
Install:
- Washer
- Spacer
- Washer
Check the О-ring [A] on the top plug and replace it with a new one if damaged.
Screw in the damper adjuster [B] of the top plug so that the distance between the adjuster bottom and the spring adjuster [C] end is 25 mm [Dj.
Holding the top plug [A] with a wrench, tighten the piston rod nut [B] against the top plug.
Torque - Piston Rod Nut: 28 N·m (2.9 kg·m, 21 ft·lb)
Raise the outer tube and screw the top plug into it.
Install the front fork (see Front Fork Installation).
