WARNING

The tires, rims, and air valves on this motorcycles
are designed only for tubeless type wheels.
The recommended standard tires, rims and air valves
must be used for replacement.
Do not install tube-type tires on tubeless rims.
The beads may not seat properly on the rim causing
Tire deflation.

Tires

Payload and Tire Pressure

Failure to maintain proper inflation pressures or observe payload limits for your tires may adversely

 affect handing and performance of your motorcycle and can result in loss of control.

The maximum recommended load on addition to vehicle weight is 180kg

 (

397lb

) , 

including rider

 passenger

,

baggage and accessories

. 

Remove the air valve cap.

Check the tire pressure often, using an accurate gauge.

Make sure to install the air valve cap securely

.

NOTE

Measure the tire pressure when the tires are cold (that is, when the motorcycle

 has not been ridden more than a mile during the past 3 hours).

Tire pressure is affected by changes in ambient temperature and altitude and so 
the tire pressure should be checked and adjusted when your riding involves wide

 variations in temperature or altitude.

Tire Wear, Damage

As the tire tread wears down, the tire becomes more susceptible to puncture and failure.

An accepted estimate is that 90% of all tire failures occur during the last 10% of tread life (90% worn).

So it is false economy and unsafe to use the tires until they are bald.

In accordance with the Periodic Maintenance Chart, measure the depth of the tread with a depth 

gauge, and replace any tire that has worn down to the minimum allowable tread depth.

Tire Depth Gauge

Visually inspect the tire for cracks and cuts, replacing the tire in case of bad damage.

Swelling or high spots indicate internal damage, requiring tire replacement.

Remove any imbedded stones or other foreign particles form the tread.

NOTE

Most countries may have their own regulations requiring a minimum tire tread 
depth; Be sure to follow them.
Have the wheel balance inspected whenever a new tire is installed.

-94-

WARNING

To ensure safe handling and stability, use only the recommended standard pressure.
Tires that have been punctures and repaired do not have the same capabilities as

 undamaged tires. Do not exceed 100km/h (60 mph) within 24 hours after repair, and
 180 km/h (110 mph) at any time after that.

NOTE

When operating on public roadways, keep maximum speed under traffic law limits.

Battery Sulfation

Sulfation occurs when the battery is left in a discharged condition for an extended time. Sulfate is a

 normal byproduct of the chemical reactions within a battery. But when continuous discharge allows

 the sulfate to crystallize in the cells,

 

the

 

battery

 

plates

 

become

 

permanently

 

damaged

 

and

 

will

 

not

 

hold

 

a

 

charge

. 

If

 

this

 

happens

, 

you

 

must

 

replace

 

it

 

with

 

a

 

new

 

battery

.

Battery Maintenance 

Always keep the battery fully charged. Failure to do so can damage the battery and result in a shorter

 

life

. 

If

 

you

 

ride

 

your

 

vehicle

 

infrequently

, 

inspect

 

the

 

battery

 

voltage

 

weekly

 

with

 

a

 

voltmeter

.

 

If

 

it

 

drops

 

below

 12.8 

volts

, 

the

 

battery

 

should

 

be

 

charged

 

with

 

an

 

appropriate

 

charger

 (

check

 

with

 

your

 

dealer

) .

If

 

you

 

will

 

not

 

use

 

the

 

vehicle

 

for

 

longer

 

than 2 weeks, the battery should be 

charged with an appropriate charger. Don

'

t use an automotive-type quick charger that may overc-

harge the battery and damage it.

Battery recharger

Contact your dealer for the charger specification.

Battery Charging

Remove

 

the

 

battery

 

from

 

the

 

vehicle

（

refer to Battery Removal

）

Attach the leads from the charger and charge the battery at a rate that is a tenth of the battery

 capacity. For example, the charging rate for a 10Ah battery would be 1.0 ampere.

Ensure that the battery is fully charged before installation.

（

see Battery Installation

）.

-96-

CAUTION

Never remove the sealing strip, or the battery can be damaged. Don't install a

 conventional battery in this motorcycle , or the electrical system can't work
 properly.

NOTE

If you charge the sealed battery, never fail to observe the instructions shown in

 the label on the battery.

-97-

Battery Removal

Remove the front seat.

Disconnect the wires from the battery, first from the (-) terminal, then the (+) terminal.

Take the battery out of the case.

Clean the battery with a solution of baking soda and water. Ensure that the wire connections are

 clean.

Battery Installation

Place the battery in the battery case.

Connect the wire to the (+) terminal first, then connect the 

wire to the (-) terminal.

CAUTION

Routing the (-) cable to the (+) terminal of the battery or 
the (+) cable to the (-) terminal can seriously damage the 
electrical system.

Headlight Beam

Horizontal Adjustment

The headlight beam is adjustable horizontally. If improperly adjusted

,

the beam will point to left or

You can use a screw driver to turn the horizontal adjuster clockwise or counterclockwise until

 

the beam points straight ahead

Vertical Adjustment

    The headlight beam is adjustable vertically. If adjusted too low, neither low nor high beam will

 illuminate the road far enough ahead. If adjusted too high, the high beam will fail to illuminate the

-100-

 road close ahead, and the low beam will blind oncoming drivers. Turn the vertical adjuster clockwise
 or counterclockwise to adjust the vertical angle of the beam. 

NOTE

On high beam, the standard point should be slightly below with the motorcycle 
on its wheels and the rider seated. Adjust the beam according to local regulations.

Cleaning Your Motorcycle

General Precautions

Keeping your motorcycle clean will improve its appearance, optimize its performance and extend the

 life of various components. Covering your motorcycle with a high quality, breathable motorcycle

 cover will help protect its finish from harmful UV rays, pollutants, and reduce the amount of dust

 

reaching

 

its

 

surfaces

.

Always wash the motorcycle before the engine and muffler cool down. 

Avoid applying degreaser to seals, brake pads, and tires.

Always use non-abrasive wax and cleaner.

Avoid all harsh chemicals, solvents, detergents, and household cleaning products like ammonia-

based window cleaners. 
Gasoline, brake fluid, and coolant will damage the finish of painted and plastic surfaces: wash them

 off immediately.

Avoid wire brushes, steel wool, and all other abrasive pads or brushes.

Be careful when washing the windshield, headlight cover, and other plastic parts as they can be

 easily scratched.

Avoid high water pressure, as it may penetrate seals and electrical components, resulting in vehicle

 damage.

Avoid spraying water in delicate areas such as air intakes, fuel line, brake components, electrical

 components, muffler outlets and fuel tank openings.

-105-

Washing Your Motorcycle

Rinse with cold water from a garden hose to remove any loose dirt.

Mix a mild neutral detergent (specified for motorcycles or automobiles) and water in bucket. Use 

a soft cloth or sponge to wash your motorcycle. If needed, use a mild degreaser to remove any oil

 or grease build up.

After washing, rinse your motorcycle with clean water to remove any residue (residue from the

 detergent can damage the components of your motorcycle.) 

Dry off your motorcycle with a soft cloth to avoid scratches.

Start the engine and allow it idle from several minutes. The heat from the engine will help dry off

 the moist areas.

Carefully ride your vehicle at a low speed and apply the brake several times. Doing so help dry the

 brakes and restores them to normal operating performance. 

Lubricate the drive chain to prevent rusting.

NOTE

After a ride in an area where the roads are salted or near the ocean, immediately wash your 
motorcycle with cold water. Don't use warm water to wash your vehicle as it accelerates the

 chemical reaction of the salt. After drying, apply an anti-corrosion sprays on all metal or
 chrome surfaces to prevent corrosion. In the case of riding in the rain or washing the 

motorcycle, condensation may form on the inside of the headlight lens. To remove the 
moisture, start the engine and turn on the headlight, gradually the condensation formed on

 the inside of the lens will clear off.
