Review on Dual-tone SoundOriginal DL168-A 500Hz High & 400Hz Low Tone Car Horn – Perfect for Golf Carts, Trucks, Cars, Motorcycles & More! by Lance Foster

I definitely like this horn as it's not too loud but is still significantly louder than the standard horn that bikes are usually fitted with. I think the Fiamm 72112 was a bit louder but the one I got broke after 4-5 days. This one is also slightly smaller (and cheaper too) than the Fiamm, so the smaller dimensions plus the shorter bearing bracket worked better on my Moto Guzzi Stelvio for space reasons.
