BMW Motorcycle Electrical Systems

The electrical system of a BMW or Triumph motorcycle contains several essential components that ensure your bike's optimal performance and reliability. The electrical system is responsible for powering your motorcycle's lights, horn, starter motor, and other electrical pieces.

How an Electrical System in a Motorcycle Works

With power stored and distributed from the battery and charged by the alternator, there are smaller and more intricate electrical components like the regulator/rectifier, ignition coils, and auxiliary cables. Each of these components plays a critical role in the motorcycle's electrical system and must remain in good condition.

Motorcycle Aux Cables

Auxiliary cables are used to connect additional electrical accessories to the motorcycle's electrical system. These accessories can include heated grips, additional lighting sources, and audio systems. It's important to use high-quality auxiliary cables that are designed to handle the electrical load of these additional accessories, and if you're installing aftermarket parts, always doublecheck to make sure you don't overload on voltage. Poor-quality cables can result in electrical problems, including short circuits and damage to the motorcycle's electrical system.

The Important of Healthy Ignition Coils in a Motorcycle

The ignition coils are another important component of a BMW or Triumph motorcycle's electrical system. They are responsible for generating the high voltage required to ignite the fuel in the engine's cylinders. Faulty ignition coils can result in engine misfires, reduced acceleration, and poor fuel economy. It's essential to use high-quality ignition coils that are designed to meet the motorcycle's specifications so that you maintain that punchy performance you're used to.

Why Battery Brackets are Important on a Motorcycle

Battery brackets are also an important component of a BMW or Triumph motorcycle's electrical system because they hold the motorcycle's battery in place. Over time, however, these brackets can come loose or bend out of shape. This can cause damage to the battery and throw off the motorcycle's electrical system. Inspect your battery bracket regularly and replace it ASAP if there are any signs of damage or wear.

Maintaining Your BMW or Triumph Motorcycle

Without a functional and reliable electrical system, your bike is a sitting duck. It is critical to maintain your bike's auxiliary cables and gnition coils, with OEM replacement parts. When the time comes to switch out old electrical components of your bike, find the high-quality parts designed to meet your motorcycle's specifications.
