Work rules

Unless specified otherwise, the ignition must be turned off during all work (models with ignition lock, models with transpon-

der key) or the motor must be at a standstill (models without ignition lock or transponder key).

Special tools are necessary for certain tasks. The tools are not a component of the vehicle, but can be ordered using the

number in parentheses. Example: bearing puller (15112017000)

Unless otherwise noted, normal conditions apply to all tasks and descriptions.

Ambient temperature

20 °C (68 °F)

Ambient air pressure

1,013 mbar (14.69 psi)

Relative air humidity

60 ± 5 %

During assembly, use new parts to replace parts which cannot be reused (e.g. self-locking screws and nuts, expansion

screws, seals, sealing rings, O-rings, pins, and lock washers).

In the case of certain screws, a screw adhesive (e.g. Loctite^®) is required. Observe the manufacturer's instructions.

If thread locker (e.g., Precote^®) has already been applied to a new part, do not apply any additional thread locker.

After disassembly, clean the parts that are to be reused and check them for damage and wear. Change damaged or worn

parts.

After completing a repair or service work, check the operating safety of the vehicle.

2.9

Environment

If you use your motorcycle responsibly, you can ensure that problems and conflicts do not occur. To protect the future of

the motorcycle sport, make sure that you use your motorcycle legally, be environmentally aware, and respect the rights of

others.

When disposing of used oil, other operating and auxiliary fluids, and used components, comply with the laws and regula-

tions of the respective country.

Because motorcycles are not subject to the EU regulations governing the disposal of used vehicles, there are no legal regu-

lations that pertain to the disposal of an end-of-life motorcycle. Your authorized GASGAS Motorcycles dealer will be glad to

advise you.

2.10

Owner's Manual

It is important that you read this Owner's Manual carefully and completely before making your first trip. The Owner's Man-

ual contains useful information and many tips on how to operate, handle, and service your motorcycle. This is the only way

to find out how best to customize the vehicle for your own use and how you can protect yourself from injury.

Tip

Store the Owner's Manual on your terminal device, for example, so that you can read it whenever you need to.

If you would like to know more about the vehicle or have questions on the material you read, please contact an authorized

GASGAS Motorcycles dealer.

The Owner's Manual is an important component of the vehicle. If the vehicle is sold, the Owner's Manual must be down-

loaded again by the new owner.

The Owner's Manual is also available for download from your authorized GASGAS Motorcycles dealer and on the GAS-

GAS Motorcycles website. A printed copy can also be ordered from your authorized GASGAS Motorcycles dealer.

IMPORTANT NOTES

3.1

Manufacturer warranty, implied warranty

The work specified in the service schedule may only be carried out in an authorized GASGAS Motorcycles workshop and

confirmed in the GASGAS Motorcycles Dealer.net, as otherwise all warranty claims will be void. Damage or secondary dam-

age caused by tampering with and/or conversions on the vehicle are not covered by the manufacturer warranty.

3.2

Fuel, auxiliary substances

Note

Environmental hazard Improper handling of fuel is a danger to the environment.

- Do not allow fuel to enter the groundwater, the soil, or the sewage system.

Use fuels and auxiliary substances in accordance with the Owner's Manual and specification.

3.3

Spare parts, accessories

For your own safety, only use spare parts and accessory products that are approved and/or recommended by

GASGAS Motorcycles and have them installed by an authorized GASGAS Motorcycles workshop. GASGAS Motorcycles

accepts no liability for other products and any resulting damage or loss.

Certain spare parts and accessory products are specified in parentheses in the descriptions. Your authorized

GASGAS Motorcycles dealer will be glad to advise you.

The latest news GASGAS Technical Accessories on your vehicle can be found on the GASGAS Motorcycles website.

International GASGAS Motorcycles website: http://www.gasgas.com

3.4

Service

A prerequisite for perfect operation and prevention of premature wear is that the service, care, and tuning work on the

engine and chassis is properly carried out as described in the Owner's Manual. An incorrect suspension setting can lead to

damage and breakage of chassis components.

Use of the vehicle under difficult conditions, such as on sand or on wet, dusty and muddy surfaces, can result in significantly

increased wear of components, such as the drive train, brake system, air filter or suspension components. For this reason, it

may be necessary to inspect or replace parts before the next scheduled service.

It is imperative that you adhere to the stipulated run-in times and service intervals. If you observe these exactly, you will

ensure a much longer service life for your motorcycle.

The relevant mileage or time interval is whichever occurs first.

3.5

Figures

The figures contained in the manual may depict special equipment.

In the interest of clarity, some components may be shown disassembled or may not be shown at all. It is not always neces-

sary to disassemble the component to perform the activity in question. Please follow the instructions in the text.

3.6

Customer service

Your authorized GASGAS Motorcycles dealer will be happy to answer any questions you may have regarding your vehicle

and GASGAS Motorcycles.

Cold start button

The cold start button 1 is fitted to the bottom of the throttle valve

body.

The electronic fuel injection system extends the injection time if the

engine is cold and the ambient temperature is low. To help the engine

burn the increased fuel quantity, it must be supplied with additional

oxygen by pushing the cold start button.

Info

Check whether the cold start button has returned to its basic

position.

6.16

Idle speed adjusting screw

The idle setting of the throttle valve body substantially influences

the vehicle’s starting behavior, a stable idle speed, and the vehicle’s

response when the throttle is opened.

An engine with a correctly set idle speed is easier to start than an engine

with the idle speed set incorrectly.

The idle speed is adjusted using the idle speed adjusting screw 1.

Info

If the idle speed is high, the engine is slow to run, the engine

brake is low and the throttle response is aggressive, the adjust-

ing screw must be turned counterclockwise.

If the idle speed is low, the engine is running fast, the engine

brake is high and the throttle response is not clean, the adjusting

screw must be turned clockwise.

For optimum performance, it is recommended to adjust the idle

speed using the dedicated functions in the diagnostics tool.

(

p. 117)

PREPARING FOR USE

– Get used to handling the motorcycle on a suitable surface before undertaking a more challenging trip.

Info

When offroad, it is recommended that you are accompanied by another person on another vehicle so that you

can help each other.

- Try also to ride as slowly as possible and in a standing position to get a better feel for the motorcycle.

- Do not make any off-road trips that exceed your ability and experience.

- Hold the handlebar firmly with both hands and keep your feet on the footrests when riding.

- If you carry luggage, make sure you secure it firmly as close as possible to the center of the vehicle and ensure even

weight distribution between the front and rear wheels.

Info

Motorcycles react sensitively to any changes of weight distribution.

- The maximum permissible overall weight and the maximum permissible axle loads must not be exceeded.

Guideline

Maximum permissible overall weight

335 kg (739 lb.)

Maximum permissible front axle load

145 kg (320 lb.)

Maximum permissible rear axle load

190 kg (419 lb.)

– Check the spoke tension. ( p. 96)

Info

The spoke tension must be checked after half an hour of operation.

- Run the engine in. ( p. 27)

8.2

Running in the engine

– During the running-in phase, do not exceed the specified engine performance.

Guideline

Maximum engine performance

During the first 3 operating hours

< 70 %

During the first 5 operating hours

< 100 %

– Avoid fully opening the throttle!

- Check the idle speed regularly.

PREPARING FOR USE

8.3

Starting power of lithium-ion batteries at low temperatures

Lithium-ion batteries are far lighter than lead batteries, have a low

self-discharge rate, and have more starting power at temperatures over

15 °C (60 °F). At low temperatures, however, the starting power of

lithium-ion batteries drops to below that of lead batteries.

Multiple starting attempts may be needed. Press the start button for

5 seconds, and wait 30 seconds between attempts. The pauses are nec-

essary so that the heat created can distribute through the lithium-ion

battery and the 12-V battery is not damaged.

If the charged lithium-ion battery is unable to actuate the starter motor

or does so only weakly when temperatures are below 6 °C (45 °F), the

402555-01

battery is not faulty but needs to be warmed up internally to increase its

starting power (current output).

The starting power increases as the battery warms up.

8.4

Preparing the vehicle for difficult operating conditions

Info

Use of the vehicle under difficult conditions, such as on sand or on wet and muddy surfaces, can result in signifi-

cantly increased wear of components, such as the drive train, brake system, or suspension components. For this

reason, it may be necessary to inspect or replace parts before the next scheduled service.

- Clean the air filter and air filter box.

(

p. 63)

Info

Check the air filter approx. every 30 minutes.

- Check the electrical connector for humidity and corrosion and to ensure it is firmly seated.

» If humidity, corrosion, or damage is found:

- Clean and dry the connector, or change it if necessary.

Difficult operating conditions are:

- Rides on dry sand. ( p. 28)

- Rides on wet sand. ( p. 29)

- Rides on wet and muddy circuits. ( p. 30)

- Rides at high temperatures or slow riding. ( p. 30)

9.2

Starting the vehicle

Danger

Danger of poisoning Exhaust gases are toxic and inhaling them may result in unconsciousness and death.

- Always make sure there is sufficient ventilation when running the engine.

- Use effective exhaust extraction when starting or running the engine in an enclosed space.

Note

Engine damage High revving speed with a cold engine negatively impacts the lifespan of the engine.

- Always run the engine warm at a low speed.

RIDING INSTRUCTIONS

- Take the motorcycle off side stand 1 and secure the side stand

with rubber strap 2.

- Shift the transmission to neutral position.

Condition

Ambient temperature: < 10 °C (< 50 °F)

- Push the cold start button in all the way.

Info

If the engine is warm, the cold start button must be

401944-10

deactivated.

- Press the start button.

Info

Do not open the throttle.

Press the start button for a maximum of 5 seconds. Wait for

30 seconds before a further attempt at starting.

At temperatures below 6 °C (45 °F), several attempts at

starting may be necessary to warm-up the lithium-ion bat-

tery and thereby increase the starting power.

During the starting process, the malfunction indicator lamp

400733-01

lights up.

9.3

Starting off

Info

Switch on the light before riding the vehicle. You will be seen earlier by other motorists.

When you are riding, the side stand must be folded up and secured with the rubber strap.

- Pull the clutch lever, shift into first gear, release the clutch lever slowly and at the same time open the throttle carefully.

9.4

Shifting, riding

Warning

Danger of accidents If you change down at high engine speed, the rear wheel blocks and the engine races.

- Do not change into a low gear at high engine speed.

Warning

Engine failure The engine will not be lubricated unless there is 2-stroke oil in the oil tank.

If the oil level warning light lights up, the 2-stroke oil is sufficient for the remaining tank of fuel.

- As soon as the oil level warning light lights up, ride for no longer than until the remaining fuel in the tank is

depleted.

- At the next opportunity add 2-stroke oil before you refuel.

- Time the oil pump if the 2-stroke oil hose has been removed or the 2-stroke oil tank has been fully depleted in

error.

Info

If you hear unusual noises while riding, stop immediately, switch off the engine, and contact an authorized GAS-

GAS Motorcycles workshop.

First-gear is used for starting off and for steep inclines.

RIDING INSTRUCTIONS

– Shift into a higher gear when conditions allow (incline, road situation, etc.). To do so, release the throttle while simulta-

neously pulling the clutch lever, shift into the next gear, release the clutch lever and open the throttle.

- If the cold start function was activated, deactivate the cold start button after the engine has warmed up.

- After reaching maximum speed by fully opening the throttle grip, turn the throttle back so it is ¾ open. This will barely

reduce the speed, but fuel consumption will be considerably lower.

- Always open the throttle only as much as the engine can handle - abrupt throttle opening increases fuel consumption.

- To shift down, apply the brakes and close the throttle at the same time.

- Pull the clutch lever and shift into a lower gear, release the clutch lever slowly, and either open the throttle or shift

again.

- Switch off the engine if running at idle speed or stationary for a long time.

Guideline

≥ 2 min

- Avoid frequent and longer slipping of the clutch. This causes the gear oil, engine and cooling system to heat up.

- Ride at a low engine speed instead of at a high engine speed with a slipping clutch.

9.5

Braking

Warning

Danger of accidents Excessively forceful application of the brakes blocks the wheels.

- Adjust application of the brakes to the respective riding situation and riding surface conditions.

Warning

Danger of accidents A spongy pressure point on the front or rear brake reduces braking efficiency.

- Check the brake system and do not continue riding until the problem is eliminated. (Your authorized GAS-

GAS Motorcycles workshop will be glad to help.)

Warning

Danger of accidents Moisture and dirt impair the brake system.

- Brake carefully several times to dry out and remove dirt from the brake linings and the brake discs.

- On sandy, wet or slippery surfaces, use the rear brake.

- Braking should always be completed before you go into a bend. Change down to a lower gear appropriate to your road

speed.

9.6

TUNING THE CHASSIS

11.1

Checking the basic chassis setting with the rider's weight

Info

When adjusting the basic chassis setting, first adjust the shock absorber and then the fork.

- For optimal motorcycle riding characteristics and to avoid damage

to forks, shock absorbers, link fork and frame, the basic settings of

the suspension components must match the rider's weight.

- As delivered, GASGAS offroad motorcycles are adjusted for an aver-

age rider's weight (with full protective clothing).

Guideline

Standard rider weight

75 … 85 kg (165 … 187 lb.)

– If the rider's weight is above or below this range, the basic setting of

the suspension components must be adjusted accordingly.

- Small weight differences can be compensated by adjusting the

spring preload, but in the case of large weight differences, the

springs must be replaced.

401030-01

11.2

Compression damping of the shock absorber

The compression damping of the shock absorber is divided into two ranges: high-speed and low-speed.

High-speed and low-speed refer to the compression speed of the rear wheel suspension and not to the vehicle speed.

The high-speed compression adjuster has an effect, for example, when landing after a jump: the rear wheel suspension

compresses quickly.

The low-speed compression adjuster has an effect, for example, when riding over long ground swells: the rear wheel sus-

pension compresses slowly.

These two ranges can be adjusted separately, although the transition between high-speed and low-speed is gradual. Thus,

modifications in the high-speed range affect the compression damping in the low-speed range and vice versa.

Checking the basic setting of the fork

Info

For various reasons, no exact rider sag can be determined for the fork.

- As with the shock absorber, smaller differences in the rider's weight

can be compensated by the spring preload.

- However, if the fork frequently bottoms out (hard end stop on com-

pression), harder springs must be fitted to avoid damage to the fork

and frame.

- If the fork feels unusually hard after extended periods of operation,

the fork legs need to be bled.

Info

Only mount tires approved and/or recommended by GASGAS Motorcycles.

Other tires could have a negative effect on handling characteristics.

The type, condition, and pressure of the tires all have a major impact on the handling characteristic of the motorcy-

cle.

Worn tires have a negative effect on handling characteristics, especially on wet surfaces.

- Check the front and rear tires for cuts, embedded objects, and other

damage.

» If the tires have cuts, run-in objects, or other damage:

- Change the tires.

- Check tread depth.

Info

Adhere to the legally required minimum tread depth.

400602-10

Minimum tread depth

≥ 2 mm (≥ 0.08 in)

» If the tread depth is less than the minimum tread depth:

- Change the tires.

- Check the tire age.

Info

The tire date of manufacture is usually contained in the tire

label and is indicated by the last four digits of the DOT num-

ber. The first two digits indicate the week of manufacture

and the last two digits the year of manufacture.

GASGAS Motorcycles recommends that the tires be changed

Checking spoke tension

Warning

Danger of accidents Incorrectly tensioned spokes impair the handling characteristic and result in secondary dam-

age.

The spokes break due to being overloaded if they are too tightly tensioned. If the tension in the spokes is too low,

then lateral and radial run-out will form in the wheel. Other spokes will become looser as a result.

- Check spoke tension regularly, and in particular on a new vehicle. (Your authorized GASGAS Motorcycles work-

shop will be glad to help.)

- Strike each spoke briefly using a screwdriver blade.

Info

The frequency of the sound depends on the spoke length

and spoke diameter.

If you hear different tone frequencies from different spokes

of equal length and diameter, this is an indication of differ-

ent spoke tensions.

You should hear a high note.

401061-01

a soft sponge.

Never apply motorcycle cleaner to a dry vehicle; always

rinse the vehicle with water first.

After rinsing the motorcycle with a gentle spray of water, allow it to

dry thoroughly.

Remove the closure of the exhaust system.

Warning

Danger of accidents Moisture and dirt impair the brake

system.

- Brake carefully several times to dry out and remove dirt

from the brake linings and the brake discs.

After cleaning, ride the vehicle a short distance until the engine

warms up.

Info

The heat produced causes water at inaccessible locations in

the engine and on the brake system to evaporate.

After the motorcycle has cooled down, lubricate all moving parts

and pivot points.

Clean the chain. ( p. 70)

–

Treat bare metal (except for brake discs and the exhaust system)

with a corrosion inhibitor.

CLEANING, CARE

Preserving materials for paints, metal and rubber ( p. 146)

- Treat all plastic parts and powder-coated parts with a mild cleaning

and care product.

Special cleaner for glossy and matte paint finishes, metal and

plastic surfaces ( p. 147)

(All EU models)

- Oil the steering lock.

Universal oil spray ( p. 147)

Checks and maintenance steps for winter operation

Info

If you use the motorcycle in winter, salt can be expected on the roads. You should therefore take precautions

against aggressive road salt.

If the vehicle has been used on salted roads, use cold water for cleaning after riding. Warm water enhances the cor-

rosive effects of salt.

- Clean the motorcycle. ( p. 127)

- Clean the brakes.

Info

After EVERY trip on salted roads, thoroughly clean the brake

calipers and brake linings, after they have cooled down and

without removing them, with cold water and dry them care-

fully.

After riding on salted roads, thoroughly clean the vehicle

401060-01

with cold water and dry it well.

- Treat engine, link fork, and all other bare or zinc-plated parts (except

the brake discs) with a wax-based corrosion inhibitor.

Info

Corrosion inhibitor must not come in contact with the brake

discs as this would greatly reduce the braking force.

- Clean the chain. ( p. 70)

STORAGE

21.1

Storage

Warning

Danger of poisoning Fuel is harmful to health.

- Avoid skin, eye and clothing contact with fuel.

- Immediately consult a doctor if you swallow fuel.

- Do not inhale fuel vapors.

- Rinse the affected area immediately with plenty of water in the event of contact with the skin.

- Rinse the eyes thoroughly with water, and consult a doctor in case of fuel contact with the eyes.

- Change your clothing if fuel spills on them.

- Keep fuels correctly in a suitable canister, and out of the reach of children.

Info

If you plan to garage the motorcycle for a longer period, perform the following steps or have them performed.

Before storing the motorcycle, check all parts for function and wear. If service, repairs, or replacements are neces-

sary, you should do this during the storage period (less workshop overload). In this way, you can avoid long work-

shop waiting times at the start of the new season.

- Clean the motorcycle. ( p. 127)

- Change the gear oil.

(
