OWNER’S SERVICE MANUAL

FOREWORD

This manual is presented as a means whereby you

can maintain your RM-Z450 in top working condi-

tion at all times. Your riding skill and the mainte-

nance steps outlined in this manual will assure you

of top performance from your machine under any

type of competition.

We sincerely wish you and your Suzuki motorcycle

a successful partnership for many years of happy

riding.

All information, illustrations, photographs and speci-

fications contained in the manual are based on the

latest product information available at the time of

publication. Due to improvements or other changes,

there may be some discrepancies in this manual.

Suzuki reserves the right to make production

changes at any time, without notice and without

incurring any obligation to make the same or similar

changes to motorcycle previous built or sold.

Suzuki Motor Corporation believes in conservation

and protection of Earth’s natural resources. To that

end, we encourage every motorcycle owner to recy-

cle, trade in, or properly dispose of, as appropriate,

used motor oil, engine coolant, and other fluid, and

tires.

GENERAL CONSIDERATIONS

• Wear a helmet and goggles

A helmet is the most important piece of gear to

wear. Helmets do not reduce essential vision or

hearing. Generally, helmets do not cause or

intensify injury if you crash. Helmets simply help

your skull protect your intelligence, your memory,

your personality, and your life.

Your eyesight is equally valuable. Wearing suit-

able eye protection can help keep your vision

unblurred by the wind and help shield your eyes

from branches and airborne matter like bugs, dirt,

or pebbles kicked up by tires. Wear a helmet and

eye protection every time you ride.

• Wear protective gear

Wear proper clothing when you ride. Avoid loose

clothes or scarves, which could get caught in

moving parts. Abrasion injuries can be minimized

by wearing protective clothing including gloves,

strong boots that fit over the ankle, long pants,

and a long sleeve shirt or jackets. Experienced

riders often wear a kidney belt and chest or back

protector for additional comfort and protection.

• Inspect your machine before riding

Before each use, perform an inspection per “Peri-

odic Inspection” section starting on page 2-3.

• No Passengers

Suzuki RMs are designed for the rider only.

• Practice on level ground

Before you begin riding, you should find a good

place to practice the skills you need to ride

safely. Find a flat, open area with enough space

to maneuver. Check with your Suzuki dealer or

call police department if you do not know where

you can ride.

Review the controls on your motorcycle before

riding.

•Knowyourlimits

Always ride within the boundaries of your own

skills. Knowing these limits and staying within

them will help you avoid accidents. Ride only in

events appropriate for your experience.

Safely competing on a motorcycle requires that

your mental and physical skills are fully part of

the experience. You should not attempt to oper-

ate a motorcycle, especially one with two wheels,

if you are tired or under the influence of alcohol

or other drugs. Alcohol, illegal drugs, and even

some prescription and over-the-counter drugs

and cause drowsiness, loss of coordination, loss

of balance, and loss of good judgement. If you

are tired or under the influence of alcohol or other

drugs, PLEASE DO NOT RIDE your motorcycle.

• Conclusion

The actions of other riders are unpredictable.

Your motorcycle’s condition can change. These

factors can best be dealt with by giving every ride

your full attention.

Circumstances beyond your control could lead to

an accident. You need to prepare for the unex-

pected by wearing a helmet and other protective

gear, and practicing safe riding techniques to

minimize the damage to you and your machine.

May all of your rides on your new Suzuki be winning

rides!
