Driving instructions
Running in
next ; Index
| DANGER |
Risk of accident! New tyres do not have their optimal roadholding at first,
therefore they must be run in. Ride cautiously for the first 100 km (60 miles)!
Even run-in tyres have to warm up before they reach their maximal roadholding. |
|
During the first few hours of operation the engine has a higher degree of internal friction.
All the moving parts have worn in.
Therefore, observe the following instructions while running in during the first 1000 km (600 mi):
0 to 150 km (0 to 90 miles):
- Vary the speed and the revs from time to time.
- Keep the revs below 6000 rpm.
Recommended speed:
gear | 1 | 2 | 3 | 4 | 5 | 6 |
km/h | 20 | 30 | 40 | 50 | 60 | 70 |
150 to 500 km (90 to 300 miles):
- Keep the revs below 8000 rpm.
Recommended speed:
gear | 1 | 2 | 3 | 4 | 5 | 6 |
km/h | 25 | 40 | 55 | 65 | 80 | 95 |
- You can use the full engine speed range in all gears up to 8000 rpm. Do not ride at full throttle!
| DANGER |
Risk of accident! New brake blocks do not reach their optimal frictional force for the first 200
km (120 miles). They must be worn in. You can compensate for the somewhat reduced braking effect
by exerting more force on the brake pedal or hand-brake. The same applies after the brake blocks
have been changed. |
|
500 to 800 km (300 to 480 miles):
- Do not ride for long distances at full throttle or longer stretches at over 8000 rpm.
After 800 km (480 miles):
- The engine load can be increased to maximum for short periods.
| ATTENTION |
The engine oil and oil filter must be changed after the first
1000 km (600 mi), see the maintenance schedule. |
|
After 1000 km (600 miles):
- You can ride at full throttle.
If the RPM exceed 10500, the ignition box switches off the ignition current
(rev limiter).
| ATTENTION |
Risk of engine and transmission damage! The revs may not go into the
area of the rev limiter. |
|
If any problems become evident during the running-in period contact an authorised MZ
Workshop without delay.
Safe driving
next ; Index
| DANGER |
Risk of accident! Check the operational safety and roadworthiness of your
motorcycle before every journey. If you notice any irregularities, the
necessary repairs must be made before starting the motorcycle! |
|
Pre-ride checks:
The following list of checks does not take very long. The increased safety gained is
worth much more than the few moments needed for the checks.
- Front and rear brakes:
Check the braking effect and brake fluid level.
- Lights and horn:
Check that the headlight, rear and brake lights, indicators, warning lights
and horn are functioning properly.
- Tyres:
Check the condition and pressure of the tyres (see section Maintenance - Tyres).
- Fuel level:
Check the fuel level and fill up if necessary (see section
Operation instructions - Refuelling).
| WARNING |
Risk of being scalded! Hot oil can spray out. Never open the cap on the oil
tank while the engine is running. |
|
| WARNING |
Risk of being scalded! Never open the cooler cap while the engine is running. |
|
- Coolant level:
Check the coolant level and top up if necessary (see section
Maintenance - Coolant).
- Driving chain:
Check the condition and slack of the chain (see section
Maintenance - Driving chain).
- Throttle twist grip:
Check for smooth opening and closing in all steering positions.
- Clutch:
Check efficiency, condition and free play (see section Maintenance - Clutch).
Individual riding styles:
| ATTENTION |
Your safety on the road is very much determined by your personal
conduct and the way you drive. |
|
Therefore:
- Do not drive when you are tired.
- Never drive when you are not fit to ride (for instance, when you are under the
influence of alcohol, drugs or medication).
- Always adjust your speed to road and traffic conditions.
- Always observe traffic regulations strictly, especially the speed limits.
- Ride your motorcycle in accordance with your riding ability.
Loading:
| WARNING |
Risk of accident! Carrying baggage affects the motor-cycle's performance and stability.
Adjust your way of riding and speed accordingly! Do not exceed the maximum authorised load. |
|
If you want to take baggage with you, please observe the following instructions:
- Keep the baggage weight as low as possible.
- Place the baggage as near as possible to the centre of gravity of the motorcycle.
- Distribute the weight as evenly as possible.
- Check regularly that the baggage is secure. No part of the baggage or its
securing gear may come into contact with any of the motorcycle's moving
parts, e.g. a wheel.
Drive economically and protect the engine and the environment
next ; Index
| WARNING |
Increased engine wear! The engine should not be warmed up while stationary! First
warm up the engine before riding at higher speeds. |
|
When the engine is idling it takes a very long time for it to reach operating temperature.
During the warm-up period the wear is especially high. Therefore, ride off with a low engine
speed shortly after starting the engine. When the engine had warmed up a higher
performance could be retrieved.
| ATTENTION |
Risk of environmental damage! Do not accelerate at full throttle! Try to
avoid driving at maximum speed! |
|
Using moderate acceleration reduces the fuel consumption, environmental damage and
engine wear considerably.
Fuel consumption, exhaust gases and vehicle noise increase disproportionately at high speeds.
| ATTENTION |
Risk of environmental damage! Do not run the engine at
higher revs than necessary. Shift up as soon as possible and shift down only if the
engine no longer runs smoothly. |
|
The fuel consumption in second gear is more than double that in top gear. Reducing the
engine speed also reduces the noise emission.
| ATTENTION |
Risk of environmental damage! Drive at a steady speed and be alert! |
|
Unnecessary acceleration and braking manoeuvres result in higher fuel consumption.
Operating instructions
Starting the engine
next ; Index
| WARNING |
Risk of poisoning! There is a danger of poisoning if the engine is run in enclosed spaces. |
|
A battery in good working condition is the prerequisite for a sure starting procedure.

- Switch the light on.
- Ride off in first gear.
| ATTENTION |
Risk of damage to the regulator, rectifier and ignition box. Never start the engine
without a or with a flat battery by pushing the motorcycle. Only use external batteries as
a starting aid when the nominal voltage of the external battery is between >12 V and a
maximum of 13.8 V, and if the capacity is not higher than your motorcycle's own battery! |
|
Changing gear
next ; Index
| ATTENTION |
Risk of damage to the gear box, engine and transmission.
Never try to change gears without disengaging the clutch. |
|
The gear change pattern is shown in Operation section.
To shift up or down, pull the clutch lever completely to the stop, change to the next
gear and then release the clutch lever slowly.
To change into neutral gear, activate the clutch while repeatedly pressing down the
foot pedal (some resistance will be noticed in first gear), then let the foot pedal up
gently.
| ATTENTION |
When starting an 125 SX/SM governed to 80 km/h, keep the engine speed below 6500 rpm.
Otherwise a quick start is impossible. |
|
Braking
next ; Index
Always apply both brakes simultaneously. Just using one brake reduces the braking effect.
| DANGER |
Risk of accident! Never brake too hard! This can lead to the
wheels locking and the motorcycle going out of control |
|
Please observe the following instructions:
- Reduce speed when approaching a curve. Braking in a curve may cause skidding.
- Apply the brakes with care on wet roads.
- On long, steep, downhill stretches use the braking effect of the engine by shifting down.
You can supplement this by applying both brakes intermittently.
Stopping the engine
