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
right 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 manu-
facturer, 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 SS-08, #10 or equivalent fork oil.

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 re-
straint exercised during its early life. The general rules are as follows.
• Keep to these break-in engine speed limits:
Initial 800 km: Below 5 000 r/min.
Up to 1 600 km: Below 8 000 r/min.
Over 1 600 km: Below 10 500 r/min.
• Upon reaching an odometer reading of 1 600 km you can subject the motorcycle to full throttle operation.
However, do not exceed 10 500 r/min. at any time.
