The 1985 BMW K100, also known as the “Flying Brick,” is one of the most iconic motorcycles produced by BMW in the 1980s. Known for its smooth inline-four engine and distinctive design, the K100 offers a unique and enjoyable riding experience. One of the key elements that contribute to the bike’s usability and overall riding experience is its handlebar controls. These controls are essential for maneuvering the motorcycle, controlling its functions, and ensuring safety. In this article, we will delve into the handlebar controls of the 1985 BMW K100, their functions, and how to maintain and troubleshoot them.
Overview of the 1985 BMW K100 Handlebar Controls
The 1985 BMW K100 features a set of ergonomic handlebar controls designed to give riders full control over the motorcycle’s operation. These controls are strategically placed for easy access, ensuring that riders can operate the bike efficiently without taking their hands off the handlebars for too long. These controls manage essential functions such as throttle, braking, signaling, and starting the engine.
Here’s a breakdown of the key handlebar controls on the 1985 BMW K100:
1. Left-Hand Controls
The left-hand side of the handlebar features several essential controls for rider convenience and safety. These controls include:
- Clutch Lever: Located on the left-hand side, the clutch lever allows riders to disengage the clutch for shifting gears. It is crucial for smooth gear transitions and starting the bike in motion.
- Turn Signal Switch: The turn signal switch is used to activate the left and right indicators. BMW equipped the K100 with an intuitive toggle switch that makes signaling while riding easy and convenient.
- Horn Button: The horn button is located just below the turn signal switch. It is used to alert other road users of your presence or to signal for attention in emergency situations.
- Headlight Dimmer Switch: The dimmer switch adjusts the headlight’s brightness. The rider can toggle between low and high beams depending on riding conditions.
- Kill Switch: Located near the left-hand grip, the kill switch is used to turn off the engine in case of an emergency. It is also used to shut off the bike when parking.
2. Right-Hand Controls
The right-hand side of the handlebar houses controls that are primarily focused on the bike’s acceleration, braking, and engine management.
- Throttle Grip: The throttle grip is located on the right handlebar and controls the engine’s speed by regulating the flow of air and fuel into the engine. Twisting the throttle toward the rider increases the engine speed (revving), while releasing it slows the engine down.
- Front Brake Lever: The front brake lever is located just below the throttle. This lever is responsible for activating the front brake of the motorcycle, helping the rider to slow down or stop the bike.
- Starter Button: Located near the throttle, the starter button is used to start the engine after the ignition switch has been turned on. Pressing the button activates the bike’s electrical system and cranks the engine.
Functions of the Handlebar Controls on the BMW K100
The handlebar controls of the BMW K100 are designed to offer intuitive functionality, ensuring that riders can operate the motorcycle with minimal effort. The placement of these controls reflects BMW’s focus on rider comfort and safety. Here’s an overview of their key functions:
Throttle
The throttle on the right-hand side of the handlebar is crucial for controlling the engine’s power. By twisting the throttle, the rider can control the speed and acceleration of the bike. It is vital for smooth acceleration and deceleration.
Clutch
The clutch lever on the left side allows the rider to disengage the clutch and change gears. Pressing the clutch lever temporarily disconnects the engine’s power from the wheels, allowing smooth gear shifts. This control is essential for starting and stopping the bike, as well as changing gears while riding.
Brakes
Both the front and rear brakes are vital components for rider safety. The front brake lever is located on the right handlebar, while the rear brake is operated by a foot pedal. Proper brake maintenance ensures that the rider has full control over the motorcycle’s stopping power.
Signals and Lighting
The BMW K100 is equipped with turn signal controls, a headlight dimmer, and a horn. The turn signal switch enables the rider to communicate their intentions to other drivers. The headlight dimmer switch ensures optimal lighting conditions for night riding. The horn button is used for alerting others, especially in emergency situations.
Engine Management
The kill switch and starter button on the left-hand side are critical for managing the engine. The kill switch instantly turns off the engine in case of emergencies, while the starter button activates the engine after the bike is in the “on” position.
Maintaining and Troubleshooting Handlebar Controls
Proper maintenance of the handlebar controls is vital for ensuring smooth operation and safety. Here are some maintenance and troubleshooting tips for the 1985 BMW K100 handlebar controls:
1. Clutch and Throttle Cables
The clutch and throttle cables should be checked regularly for signs of wear or damage. Over time, these cables can stretch or fray, making it difficult to engage the clutch or control the throttle smoothly. Lubricating the cables and adjusting their tension can help maintain their responsiveness.
2. Brake Levers and Cables
Both the front and rear brake levers should be checked for proper function. Ensure that the brake fluid is at the correct level and that the brake lines are not cracked or leaking. Brake pads should be inspected for wear, and the brake levers should have a firm, responsive feel when pressed.
3. Electrical Connections
The electrical components, such as the turn signal switch, horn button, and starter button, should be cleaned and checked for corrosion. Loose or damaged wiring can lead to malfunctioning controls, so ensure that all connections are secure and properly insulated.
4. Adjusting the Clutch and Throttle Levers
If you find that the clutch or throttle levers are too stiff or too loose, adjustments may be necessary. For the clutch, ensure that there’s proper free play in the lever. For the throttle, check the grip for any binding and ensure that it moves smoothly when twisted.
5. Replacing Faulty Components
If any of the handlebar controls become damaged or worn out, it’s important to replace them immediately. Common issues include broken levers, malfunctioning switches, or faulty cables. Replacing these parts with high-quality OEM or aftermarket parts ensures that your bike remains in safe, working condition.
Conclusion
The handlebar controls on the 1985 BMW K100 are integral to the rider’s experience, providing easy access to crucial functions such as braking, acceleration, signaling, and engine management. Proper maintenance and adjustment of these controls can greatly enhance the riding experience, ensuring that the bike operates smoothly and safely. Whether you’re replacing worn-out components or fine-tuning your control settings, paying attention to the handlebar controls will keep your BMW K100 in optimal condition for years to come.
