Fork Oil Level (fork fully compressed)
Fork oil level chart
Warning! Any variation from the figures quoted in the fork oil level chart could result in an unsafe riding condition leading to loss of motorcycle control and an accident.
Fork Leg | Oil Level* | Oil Volume | Oil Grade |
Left Hand | 60 mm | 557 cc | Showa SS47 |
Right Hand | 60 mm | 534 cc | |
* Fork fully compressed with the spring, upper spring collar and preload/damping assembly fitted. |
Warning! Make sure that the upper spring collar is fitted in the correct orientation as noted during removal. Incorrectly assembled components could lead to an unsafe riding condition resulting in loss of motorcycle control and an accident.
1. Fit the spring and upper spring collar into the fork inner tube as noted during removal.

1. Upper spring collar; 2. Spring; 3. Fork outer tube
2. Fill the fork with the specified fork oil until the oil level passes the side holes in the fork inner tube.

1. Hole (one of four shown); 2. Fork inner tube
3. Pump the fork outer tube several times to expel any trapped air then fully compress the fork and support it in an upright position. Leave the fork for a few minutes to allow the oil level to stabilise.
Warning!
- The left hand and right hand fork leg assembles differ internally, with the left fork leg containing an adjustable preload assembly and the right fork leg containing an adjustable damping assembly.
- If these components are fitted to the wrong fork, the front suspension will not function correctly which may lead to loss of motorcycle control and an accident.
Note:
- Ensure the preload assembly is fitted to the left hand fork leg. The preload assembly is identified by its shorter preload rod guide case. The top cap has a single preload adjuster.
- Ensure the damper assembly is fitted to the right hand fork leg. The damper assembly is identified by its longer damper rod guide case. The top cap has two damping adjusters labelled TEN and COM.
- The method for installing the preload or damping assembly and setting the oil level is the same for both forks. However, a different volume of oil will be required for each fork to achieve the oil level settings detailed above.
- When fitting the fork top cap and fork preload/damping assembly, care must be taken not to damage the top ring of the assembly.

1. Preload assembly (left fork leg); 2. Preload rod guide case; 3. Damper assembly (right fork leg); 4. Damper rod guide case; 5. Top caps
4. With the fork fully compressed use T3880367 - Wrench, Damper Cylinder, 33mm to fit the fork preload/damping assembly to the inner tube.

1. T3880367 - Wrench, Damper Cylinder, 33mm; 2. Top cap; 3. Preload/Damper rod; 4. Fork outer tube
5. With the lower end of the fork inner tube secure in T3880171 - Fork Holding Tool, tighten the preload/damping assembly to 90 Nm using a torque wrench fitted with a suitable crow foot spanner adapter (see Use of Crow Foot Spanner Adapters with Torque Wrenches).
6. Fill the fork with the specified fork oil until the oil level passes over the preload/damping rod guide case.

7. Pump the fork several times to expel any trapped air then fully compress the fork and support it in an upright position. Leave the fork for a few minutes to allow the oil level to stabilise.
8. Refer to the oil level chart and set the scale on T3880160 - Fork Oil Filler/Evacuator to the specified level.

1. T3880160 - Fork Oil Filler/Evacuator; 2. Adjuster plate; 3. Scale area; 4. Hole (zero position)
Note: Zero level on the tool is set at the small exit hole in the side of the scale tube, NOT AT THE END TIP. Do not attempt to block this side hole as this will cause the final fluid level to be incorrect.
9. Insert the scale end of the tool into the fork inner tube.
10. Hold the tool adjuster plate level with the upper surface of the fork outer tube and draw fluid into the syringe until fluid flow ceases (empty the syringe if the body becomes full before fluid flow stops).
11. The fluid level in the fork is now set to the height set on the tool scale. Check the tool scale setting and repeat the process if incorrectly set.
12. Fit a new O-ring to the top cap.
13. Lubricate the O-ring on the top cap with a smear of clean fork oil then screw the top cap fully into the outer tube.
14. Using T3880186 - 45 mm Octagonal Socket tighten the top cap to 35 Nm.
Note: It is much easier to tighten the top cap when the fork has been refitted.
