FUEL AND OIL RECOMMENDATION

FUEL

Gasoline used should be graded 91 octane (Research Method) or higher. Unleaded gasoline is recom-
mended.

ENGINE OIL

Use a premium quality 4-stroke motor oil to ensure longer ser-
vice life of your motorcycle. Use only oils which are rated SF or
SG under the API service classification.
The recommended viscosity is SAE 10W-40. If an SAE 10W-40
motor oil is not available, select an alternative according to the
following chart.

BRAKE FLUID

Specification and classification: DOT 4
!
Since the brake system of this motorcycle is filled with a glycol-based brake fluid by the manufac-
turer, do not use or mix different types of fluid such as silicone-based and petroleum-based fluid
for refilling the system, otherwise serious damage will result.
Do not use any brake fluid taken from old or used or unsealed containers.
Never re-use brake fluid left over from a previous servicing, which has been stored for a long
period.

FRONT FORK OIL

Use fork oil #10.

BREAK-IN PROCEDURES

During manufacture only the best possible materials are used and all machined parts are finished to a very
high standard but it is still necessary to allow the moving parts to "BREAK-IN" before subjecting the engine to
maximum stresses. The future performance and reliability of the engine depends on the care and restraint
exercised during its early life. The general rules are as follows.
• Keep to these break-in procedures:
Initial 800 km : Less than 1/2 throttle
Up to 1 600 km : Less than 3/4 throttle
• Upon reaching an odometer reading of 1 600 km you can subject the motorcycle to full throttle operation.
• Do not maintain constant engine speed for an extended time period during any portion of the break-in. Try
to vary the throttle position.
