Maintenance Fundamentals
*1. The JASO T 903 standard is an index for engine
oils for 4-stroke motorcycle engines. There are
two classes: MA and MB. For example, the
following label shows the MA classification.
*2. The SAE standard grades oils by their viscosity.
*3. The API classification specifies the quality and
performance rating of engine oils. Use SG or
higher oils, excluding oils marked as "Energy
Conserving" or "Resource Conserving" on the
circular API service symbol.

Brake Fluid
Do not add or replace brake fluid, except in an
emergency. Use only fresh brake fluid from a
sealed container. If you do add fluid, have the
brake system serviced by your dealer as soon as
possible.
NOTICE
Brake fluid can damage plastic and painted surfaces.
Wipe up spills immediately and wash thoroughly.
Recommended brake fluid:
Honda DOT 4 Brake Fluid or equivalent
Drive Chain
The drive chain must be inspected and lubricated
regularly. Inspect the chain more frequently if you often
ride on bad roads, ride at high speed, or ride with
repeated fast acceleration.
2
If the chain does not move smoothly, makes strange
noises, has damaged rollers, has loose pins, has missing
O-rings, or kinks, have the chain inspected by your
dealer.
