Maintenance

A prerequisite for perfect operation and prevention of wear is that the engine and chassis maintenance and adjustment work described in the owner's manual are properly carried out. Poor adjustment and tuning of the engine and chassis can lead to damage and breakage of components.

Using the motorcycle in extreme conditions such as very muddy or wet terrain can lead to above-average wear of components such as the transmission train or the brakes. For this reason, it may be necessary to service or replace worn parts before the limit specified in the greasing and service table is reached.

Pay careful attention to the prescribed running-in period, inspection and maintenance intervals. If you observe these exactly, you will ensure a much longer service life for your motorcycle.

Warranty

The maintenance work prescribed in the greasing and service table must be carried out in an authorized KTM workshop and confirmed in the customer's service record, since otherwise no warranty claims will be recognized. No warranty claims can be considered for damage resulting from manipulations and alterations to the motorcycle.

Fuel, oils, etc.

You should use the fuels, oils and greases according to specifications as listed in the owner's manual.

Spare parts, accessories

For your own safety, use only spare parts and accessories approved by KTM. KTM accepts no liability for other products and any resulting damage or loss.

Transport

Note

Danger of damage Danger of damage by the vehicle running away or falling over.

Note

Fire hazard Some components (engine, radiator and exhaust system) get very hot when the engine is running.

Environment

Offroad motorcycling is a wonderful sport and we naturally hope that you will be able to enjoy it to the fullest. However, it is a potential problem for the environment and can lead to conflicts with other persons. But if you use your motorcycle responsibly, you can ensure that such problems and conflicts do not have to occur. To protect the future of motorcycle sport, make sure that you use your motorcycle legally, display environmental consciousness, and respect the rights of others.

Checking the basic chassis setting with the rider's weight

KTM 450 EXC-R UK - Checking the basic chassis setting with the rider's weight - 1

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, swing arm and frame, the basic settings of the suspension components must match your body weight.
- As delivered, KTM offroad motorcycles are adjusted for a standard rider weight (with full protective clothing).

Specification

Standard rider weight

75...85kg(165...187lb.)

If your weight is above or below the standard range, you have to adjust the basic setting of the suspension components 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.

Compression damping of shock absorber

The shock absorber can regulate compression damping in low- and high-speed range separately (Dual Compression Control).

The term low and high speed refers to the movement of the shock absorber during compression and not the riding speed of the motor-cycle.

The low- and high-speed technology works non-specifically.

KTM 450 EXC-R UK - Danger - 1

Info

If there is a big engine speed rise, reduce the idle speed to a normal level and repeat the above steps.

The extremely sporty rider will set the mixture about 1/4 of a turn back from this ideal value (leaner, in a clockwise direction) since the engine becomes hotter in sporting use.

If the procedure described here does not lead to satisfactory results, the cause may be a wrongly dimensioned idling jet.

If you can turn the idle adjusting screw to the end without any change of engine speed, you have to fit a smaller idling jet.

The idle adjusting screw must not be opened more than two turns. If more than two turns are necessary (rich mixture), use a larger idling jet.

After changing the idling jet, start from the beginning with the adjusting steps.

  • Dispose of oil, grease, filters, fuel, cleaning substances, brake fluid, batteries, etc. according to regulations.

KTM 450 EXC-R UK - Warning - 1

Info

If you clean the motorcycle regularly, its value and appearance are maintained over a long period.

Avoid direct sunshine on the motorcycle during cleaning.

Before you clean the motorcycle, seal the exhaust system to prevent penetration by water.
- First remove coarse dirt particles with a gentle water spray.
Spray very dirty areas with a normal motorcycle cleaner and then clean with a paintbrush.

Motorcycle cleaner (P. 115)

KTM 450 EXC-R UK - Info - 1

Info

Warning

Danger of accidents Reduced braking due to wet or dirty brakes.

Clean or dry dirty or wet brakes by riding and braking gently.

After cleaning, ride the vehicle a short distance until the engine warms up, and then apply the brakes.

KTM 450 EXC-R UK - Warning - 1

Info

The heat produced causes water at inaccessible positions in the engine and the brakes to evaporate.

  • Push back the protection covers on the handlebar instruments to allow water to evaporate.
    After the motorcycle has cooled off, oil or grease all moving parts and bearings.
    Clean the chain. (P. 50)
    Treat bare metal parts (except for brake discs and exhaust system) with anti-corrosion materials.

Cleaning and polishing materials for metal, rubber and plastic (P. 115)

Treat all painted parts with a mild paint polish.

High-luster polish for paint (P. 116)

  • To prevent electrical problems, treat electric contacts and switches with contact spray.

Contact spray (P. 116)

Info

If you want to garage the motorcycle for a longer period, take the following actions.

Before storing the motorcycle, check all parts for function and wear. If service, repairs or replacements are necessary, you should do this during the storage period (less workshop overload). In this way, you can avoid long workshop waiting times at the start of the new season.

Clean the motorcycle. (P. 86)
- Change the engine oil and oil filter and clean the engine oil screen. (P. 79)
- Change the gear oil and clean the gear oil screen. (P. 82)
- Check the antifreeze and coolant level. (P. 71)
- Drain the fuel from the tanks into a suitable container.

KTM 450 EXC-R UK - Info - 1

Info

KTM recommends propping up the motorcycle.

  • Jack up the motorcycle. (P. 32)
    Cover the motorcycle with a porous sheet or blanket. Do not use non-porous materials since they prevent humidity from escaping, thus causing corrosion.

KTM 450 EXC-R UK - Info - 1

Info

Avoid running the engine for a short time only. Since the engine cannot warm up properly, the water vapor produced during combustion condenses and causes valves and exhaust system to rust.

JAS0 T903 MA

Different technical development directions required a new specification for 4-stroke motorcycles – the JASO T903 MA Standard. Earlier, engine oils from the automobile industry were used for 4-stroke motorcycles because there was no separate motorcycle specification. Whereas long service intervals are demanded for automobile engines, high performance at high engine speeds are in the foreground for motorcycle engines. With most motorcycles, the gearbox and the clutch are lubricated with the oil as the engine. The JASO MA Standard meets these special requirements.

SAE

The SAE viscosity classes were defined by the Society of Automotive Engineers and are used for classifying oils according to their viscosity. The viscosity describes only one property of oil and says nothing about quality.
