Do Motorcycles Have Horns? Yes But They Aren’t Good Enough

A horn is an essential requirement for a motorcycle to be considered roadworthy and street-legal. As such, most if not all mass-produced street bikes have horns. A horn in a bike is similar to that of a car or truck, and the purpose is to warn others. 

The use of a horn is a part of safety in some countries. In Italy, if you’re leading up a steep hill on a zig-zag road and you can’t see the oncoming traffic, or on a narrow road with a blind corner, you need to use your horn to signify your presence. In the USA, road users use the horn as a way of life for road users. Hence, the noise pollution. In Japan, it’s not a good idea to honk your horn. Although drivers use them, it’s only when necessary.

This website has a comprehensive list of state laws related to horns.

The problem with stock horns

Many riders believe that a loud horn saves lives. The problem? most manufacturers install horns that, although legally compliant, are too puny if not annoying. Most riders want to replace the stock horns with aftermarket ones. 

However, horn brands and models come with a pre-made wiring harness that’s ready to install, so cutting or tapping into the motorcycle’s wiring is unnecessary. An example of this is Murph’s kit, which offers a perfect well-designed harness whether you want a single or dual horn setup. RevZilla offers similar equipment.

With motorcycle riders getting more popular, more and more motorcyclists are out on the road.

It’s far less safe to ride a motorcycle than to drive a car or ride a bike. No matter how experienced you are, riding a motorcycle is dangerous.

Bikes are pretty fast, and since you’re in a hurry to complete your journey, you need to be focused all the time on the road ahead.

If you are a motorcycle rider, you will also need to watch out for other riders ahead or in close range. The last thing you want to do is crash into another biker or car driver. To ensure that doesn’t happen, you will need a motorcycle horn loud enough to catch attention.

Every motorcycle comes with a factory horn. However, sometimes it isn’t enough. Your best alternative is to get a significantly louder horn, so you can alert other motorists and pedestrians and mitigate the possibility of an accident.
