Motorcycle Consumer News had a horn comparison in their latest issue .... They showed the Stebel pulling around 8 Amps.
Slight correction, 18 amps .
I too separated the Stebel into two pieces connected by a hose on my Concours 14. There is a slight delay in sound as it spins
up which is more noticeable if you pair it with an instantaneous horn like I did, a low tone Fiamm freeway blaster (about 4+ amps IIRC).
The Stebel Nautilus is a loud horn, however some of the write ups are a little
too generous. I'll admit that I have not ever heard two Stebels activated
at the same time, but I have doubts about them sounding like
...sounds very much like a semi truck's horn on steroids!
I think that "an angry driver in a large Mercedes " would be more accurate.
From my experience,
the article in MCN seems pretty much right on the money. (links may break with time passage)
