Horn (buzzer) -BGM ORIGINAL- BACHEL 12V AC for Vespa

Original look as from the factory, but suitable for modern conversions: This 12V AC snare replaces the early 6V version on classic Vespa models without battery (Wideframe and selected Largeframe). Made in Italy, manufactured on the original tools and exclusively for BGM Original.

12V AC ratchet Like original ex works Made in Italy For models without battery 6-hole mounting

Field of application

Many classic Vespa models run without a battery with an AC electrical system - including Wideframe and selected Largeframe models. It is ideal if you have converted your Vespa to a modern alternator and ignition with 12V, but want to retain the classic look and original mounting.

Why replacement makes sense

Original look, but 12V: This BGM ORIGINAL version looks like the factory version, but is designed as a 12V AC version for conversions to a modern alternator and ignition.
The inner workings of old buzzers and horns often suffer over decades due to corrosion - the sound becomes weak or stops altogether.
In today's traffic, a functioning horn is a real safety feature.

Fitting instructions

Suitable for vehicles without battery with 12V AC vehicle electrical system.
Original design with 6-hole mounting (bolt circle Ø 65 mm) for easy installation.

AC or DC - briefly explained

AC means alternating current, i.e. alternating voltage. On AC vehicle electrical systems without a battery, buzzers are generally used, recognizable by a pitch that rises and falls with the engine speed.
DC means direct current, i.e. direct voltage. A real horn sounds constantly, regardless of the engine speed, and is usually used on vehicle electrical systems with a battery.

FAQ

This version is designed for 12V AC. It is ideal if the vehicle has been converted from 6V to 12V (modern alternator and ignition) and the original look is to be retained.
A buzzer (AC) changes pitch with the speed. A horn (DC) sounds constant and typically requires a DC on-board power supply (usually with a battery).
With 12V AC, a horn rectifier can be retrofitted. This converts the AC voltage for the horn into DC voltage if a snare is not accepted. If no DC horn is available for the original mounting location on the front of your scooter (horn cascade), a conventional DC horn can alternatively be mounted elsewhere (e.g. under the side cover on the left) and the original snare can remain on the front of the vehicle as an optical element.
