! WARNING

• The brake system of this motorcycle is filled with a glycol-based brake fluid. Do not use or mix different types of fluid such as silicone-based or petroleum-based. Do not use any brake fluid taken from old, used or unsealed containers. Never re-use brake fluid left over from the last servicing or stored for a long period.
• Brake fluid, if it leaks, will interfere with safe running and immediately discolor painted surfaces. Check the brake hoses and hose joints for cracks and fluid leakage before riding.

Brake Fluid Level Check

1) Keep the motorcycle upright and place the handlebars straight.

2) Check the brake fluid level by observing the lower limit lines on the front and rear brake fluid reservoirs.

3) When the level is below the lower limit line, replenish with brake fluid that meets the following specification.

Specification and classification
DOT 4

Brake Pad Check

The extent of brake pad wear can be checked by observing the grooved limit line "A" on the pad. When the wear exceeds the grooved limit line, replace the pads with the new ones. Refer to "Front Brake Pad Replacement" and "Rear Brake Pad Replacement".

! CAUTION Replace the brake pad as a set, otherwise braking performance will be adversely affected.

Front Brake Hose Inspection

Inspect the front brake hoses and hose joints for crack, damage or fluid leakage. If any defects are found, replace the brake hose with a new one.

Rear Brake Hose Inspection

Inspect the rear brake hose for crack, damage or fluid leakage. If any defects are found, replace the brake hose with a new one.

Tire Tread Condition

Operating the motorcycle with excessively worn tires will decrease riding stability and consequently invite a dangerous situation. It is highly recommended to replace a tire when the remaining depth of tire tread reaches the following specification.

Special tool : 09900-20805 (Tire depth gauge)

Tire tread depth (Service Limit)
FRONT: 1.6 mm (0.06 in)
REAR: 2.0 mm (0.08 in)

Tire Pressure

If the tire pressure is too high or too low, steering will be adversely affected and tire wear increased. Therefore, maintain the correct tire pressure for good roadability or shorter tire life will result. Cold inflation tire pressure is as follows.

Cold inflation tire pressure
