This lesson focuses on the critical pre-ride maintenance of your motorcycle, covering the mechanical systems you must inspect before every journey. As part of our comprehensive A and A1 motorcycle course, you will learn how to verify your lights, adjust your mirrors for optimal visibility, and inspect your drive chain for safety. These routines are vital for your practical safety and represent key topics found in the Swiss motorcycle theory exam.
Lesson content overview
Ensuring the optimal functionality of your motorcycle's lights, mirrors, and drive chain is not merely a matter of routine maintenance; it is a critical component of rider safety and legal compliance. This lesson provides a comprehensive guide to inspecting, adjusting, and maintaining these vital systems, which collectively enhance your visibility, awareness, and the reliable operation of your motorcycle within the framework of the Swiss Motorcycle Licence Theory Course for Categories A and A1.
Regular upkeep of these components directly impacts your ability to navigate traffic safely, communicate your intentions to other road users, and maintain precise control over your vehicle. Neglecting these areas can lead to reduced conspicuity, impaired situational awareness, and potential mechanical failure, all of which significantly increase the risk of accidents.
The lighting system on your motorcycle plays a dual role: it illuminates your path, allowing you to see hazards, and, crucially, it ensures that other road users can see you. Proper functionality and correct usage of all lights are paramount, especially given that motorcycles have a smaller frontal area and can be less conspicuous than larger vehicles.
Before every ride, and especially before night journeys or in adverse weather, a thorough check of all lighting components is essential. This ensures that your motorcycle meets safety standards and legal requirements, enhancing your conspicuity on the road.
Headlamp: The headlamp is your primary source of forward illumination. Motorcycles are generally required to have their dipped beam (low beam) on at all times in Switzerland, even during daylight hours, to enhance visibility. You must check both the dipped beam and the main beam (high beam) for proper operation. Ensure the light cast by the headlamp is clear and unobstructed by dirt or damage to the lens.
Taillight: The taillight provides rear illumination, making your motorcycle visible from behind. Its constant operation is vital, particularly at dusk, dawn, night, or in poor weather. A non-functional taillight significantly increases the risk of a rear-end collision.
Brake Light: The brake light illuminates when you apply the brakes, signaling your deceleration to following traffic. It is activated by both the front and rear brake levers. Test both activations to ensure both switches are working correctly.
Turn Signals (Indicators): Turn signals communicate your intention to turn or change lanes. Check that all four signals flash at a consistent rate and that their lenses are clean and undamaged. Delayed or absent signaling can lead to confusion and dangerous situations for other road users.
Hazard Warning Lights: These lights flash simultaneously to warn other drivers that your vehicle is stationary and potentially posing a hazard, or during an emergency. Ensure they activate and flash correctly.
When checking lights, it's often easiest to do so with the engine running to ensure proper power supply. Stand at a distance around your motorcycle to observe all lights from various angles.
The appropriate selection between dipped and main beam is crucial for both your visibility and the safety of other road users. Misuse of these beams can lead to dangerous glare, impairing other drivers' vision.
The low-intensity headlamp setting that provides a wide-spread illumination for normal night riding. It is designed not to dazzle oncoming traffic and is generally mandatory for continuous use during the day in Switzerland.
The high-intensity headlamp setting that offers longer-range illumination for increased visibility on unlit roads. Its powerful light beam can temporarily blind other drivers if used incorrectly.
When to Use Dipped Beam:
When to Use Main Beam:
Failing to switch from main beam to dipped beam when approaching or following other vehicles is not only dangerous but also a legal offence in Switzerland, potentially resulting in fines.
Mirrors are fundamental for maintaining awareness of your surroundings, enabling safe lane changes, overtaking maneuvers, and general traffic monitoring. Correct adjustment and cleanliness are just as important as their presence.
The effective use of rearview mirrors hinges on their correct positioning. An improperly adjusted mirror can create dangerously large blind spots.
Adjusting Your Mirrors:
Swiss road traffic regulations mandate that motorcycles must be equipped with at least one functional rearview mirror.
While a right (near-side) mirror is generally mandatory, an additional left (off-side) mirror is highly recommended for all riders and is often a requirement for specific training categories (A and A1) to ensure comprehensive rearward visibility. Both mirrors must be clean, undamaged, and securely fixed, providing a clear, undistorted view.
Even with perfectly adjusted mirrors, blind spots will always exist. Always perform a quick head check (a brief glance over your shoulder) before changing lanes or making significant lateral movements to confirm the path is clear.
The drive chain is a vital component responsible for transmitting power from the engine to the rear wheel. Its condition directly affects your motorcycle's performance, fuel efficiency, and, most importantly, safety. Neglecting chain maintenance can lead to accelerated wear, poor power delivery, and even catastrophic chain failure, resulting in a sudden loss of drive.
Correct chain tension is paramount. A chain that is too loose can whip, jump off the sprockets, or damage other components. A chain that is too tight increases wear on the chain, sprockets, and gearbox bearings, and can restrict the rear suspension's movement.
Position the Motorcycle: Place your motorcycle on its side stand or a paddock stand so the rear wheel is off the ground or the suspension is fully extended, depending on manufacturer recommendations.
Locate Midpoint: Find the midpoint between the front (countershaft) and rear (sprocket) sprockets.
Measure Slack: Gently push the chain upwards with one finger until it resists, then pull it downwards until it resists. Measure the total vertical movement (slack) between these two points.
Compare to Specifications: Consult your motorcycle's owner's manual for the manufacturer-specified chain slack, typically expressed in millimeters (e.g., 20-30 mm).
Adjust if Necessary: If the tension is outside the specified range, it must be adjusted. This usually involves loosening the rear axle nut, adjusting the chain adjusters on both sides of the swingarm equally, and then re-tightening the axle nut to the correct torque.
Regular cleaning and lubrication are essential for extending chain life and maintaining smooth power transmission. Dirt, grit, and old lubricant combine to form an abrasive paste that rapidly wears down the chain and sprockets.
Prepare the Area: Place cardboard or a drip tray under the chain to catch excess cleaner and lubricant.
Clean the Chain: Use a dedicated chain cleaner (or kerosene/paraffin, never gasoline) and a soft brush (a toothbrush or specific chain brush) to remove dirt, grime, and old grease. Work in sections, rotating the wheel carefully.
Rinse and Dry: Allow the chain cleaner to evaporate or wipe the chain dry with a clean rag. Ensure it is completely dry before lubricating.
Lubricate: Apply a specialized motorcycle chain lubricant evenly to the inside of the chain (where it meets the sprockets) while rotating the rear wheel. Aim for the O-rings or X-rings to ensure proper penetration.
Allow to Set: Let the lubricant penetrate and set for at least 15-20 minutes, or as recommended by the lubricant manufacturer, before riding. This prevents excess lube from flinging off.
Lubricate your chain approximately every 500-1000 km, or more frequently if riding in wet, dusty, or dirty conditions. Always clean and lubricate after riding in rain to prevent rust.
Chains are wear items and will eventually need replacement. Recognizing the signs of wear can prevent unexpected failure and further damage to your motorcycle.
Signs of Chain Wear:
Adhering to vehicle maintenance standards is a legal obligation for all riders in Switzerland. These regulations are designed to ensure road safety for everyone.
While specific chain tension or lubrication intervals may not be explicitly legislated in numerical values, the overall requirement for a "roadworthy" vehicle includes the functional integrity of all essential components. A poorly maintained chain that poses a risk of failure would render the vehicle non-roadworthy, potentially leading to fines or consequences in the event of an accident. Regular inspection and maintenance, as per manufacturer guidelines, are therefore implicitly mandatory.
Neglecting routine checks and maintenance can lead to dangerous situations and legal penalties. Understanding common mistakes can help you avoid them.
The environment and conditions in which you ride influence how frequently and thoroughly you need to perform maintenance and how you use your motorcycle's features.
The principles underlying effective maintenance of lights, mirrors, and chain are deeply rooted in road safety and vehicle dynamics:
Data-driven insights reinforce these points: studies consistently show that motorcycles with non-functional or improperly used lighting systems have a significantly higher crash involvement rate, especially at night or in poor visibility. Similarly, issues with the drivetrain can lead to unexpected loss of control or propulsion, which can be catastrophic.
This lesson covers the essential pre-ride maintenance checks required for motorcycle lights, mirrors, and drive chain in Switzerland. Learners must understand that dipped beam is legally mandatory during daylight hours and that all lighting components must be fully functional for road legality and conspicuity. Proper mirror adjustment while seated in riding gear minimizes blind spots, but a head check is always necessary before lateral movements. Chain maintenance involves checking tension against manufacturer specifications, cleaning with appropriate solvents, and lubricating every 500-1000 km to prevent wear and catastrophic failure. Swiss regulations under Art. 46-48 mandate proper light usage, and neglecting these maintenance routines not only creates safety hazards but can result in fines and liability in accidents.
A short set of high-value points that capture the most important learning from this lesson.
In Switzerland, motorcycles must have dipped beam headlights on at all times during daylight hours, even when the sun is shining.
Mirrors should be adjusted while seated in your normal riding position, with only a small portion of your shoulder visible at the innermost edge.
Chain slack must be measured at the midpoint between front and rear sprockets, and the total vertical movement should match manufacturer specifications.
All lights must be checked before every ride as non-functional lighting significantly increases crash risk and violates roadworthiness requirements.
A chain that requires frequent tension adjustment or shows kinks, rust, or worn sprocket teeth has likely exceeded its service life and needs replacement.

Use dipped beam when approaching oncoming traffic, following other vehicles, in urban areas, and in fog or heavy rain; reserve main beam for unlit roads with no traffic within approximately 150 meters.
Clean and lubricate your chain every 500-1000 km, or more often in wet, dusty conditions, and always after riding in rain to prevent rust.
Swiss law requires motorcycles to have at least one functional rearview mirror, but for training categories A and A1, both left and right mirrors are effectively mandatory.
When checking chain wear, if you can see more than half a tooth of the rear sprocket when the chain is lifted at the 3 o'clock position, the chain is likely worn beyond safe limits.
Always perform a head check over your shoulder before changing lanes, even if your mirrors appear perfectly adjusted, to compensate for inherent blind spots.
Riding with main beam activated in traffic, urban areas, or when following another vehicle, which can blind other road users and is a legal offence in Switzerland.
Adjusting mirrors while standing beside the bike rather than seated in the riding position, leading to incorrect field of view once actually riding.
Using gasoline to clean the chain, which damages O-rings and X-rings; only use dedicated chain cleaners or kerosene/paraffin.
Failing to lubricate the chain after cleaning before it is completely dry, preventing proper lubricant penetration and reducing effectiveness.
Installing a new chain on worn sprockets, which causes the new chain to wear unevenly and fail prematurely; always replace both sprockets with a new chain.
