This page includes a listing of our motorcycle horn reviews and accessory reviews. Some of the reviews have decible ratings for the horns and there also a couple of motorcycle horn comparison reviews. Note that you may need a motorcycle horn wiring harness with a relay to get the most and “cleanest” power to your new horn and we have a couple of reviews of those also.
A The Soundbomb horn has a variant that splits the compressor from the horn trumpets. It doesn’t necessarily make mounting any easier but it did help on the Versys 650. We found a unique location for both.
This detailed article compares the Hella Supertone; Fiamm Freeway Blasters; Stebel Magnum; Stebel Nautilus Max; and the Stebel Nautilus Compact motorcycle horns. Includes decibel ratings and comparisons.

Air Horn Notes: From “L.H.”: “I was reading through info on horns. I noticed that the add for Wolo 419 Bad Boy looks exactly like the Stebel compact air horn. Wolo seems to charge for a few decals and cosmetic alterations. In addition the advertisement’s instructions imply that you simply attach the wires from the original horn. That is misleading since a relay is needed and comes with the Stebel.”
