Stebel Nautilus Horn

[Dahoum]

I got an unused Nautilus for sale if anyone is interested. Bought and fitted the Magnum and more than satisfied although my last one died probably through water ingress. New one wrapped in a couple of miles of cling film!

If you fit the magnum as adirect replacement to a 1200 water does gather in the base of the horn. Using it the next time calls forth a large wet farting sound (almost as embarrassing as the oem 'horn').

A simple cure is to drill a small hole in the lowest part of the horn - water drains straight out - no dying horn, no farting sounds

Yes you did see me tosser!!!

A BLAHHH actually makes them stand upright in their car seats for their mis demeniour

Fitted a Nautilus Horn replacing the impressively loud magnum to my 1150GS and then tried it while still in the garage (even after reading on this site not to). Oh its loud! New under pants loud!!

Putting my safety head on for a moment, sound pressure (decibels) is measured as a logarithmic scale, so for every three decibels increase equals a doubling of sound pressure.
The Nautilus is 139dba and the Magnum is 136dba so the Nautilus is roughly twice as loud as the magnum.

Oh yea!!! without a doubt.

Yes but ... "twices as loud" on a meter/power scale.

The human ear can only just detect a 3dB change. So to us humans 3 dB does not sound twice as loud.

Sorry....

Sorry folks.... but if you need your horn then you need your brakes

Never used my horn, dunno where it is

The person you're using your horn to warn of your presence, the car door about to open, the child at the side of the road playing, the car about to swap lanes.... they might be deaf, or listening to the 1812 at full volume!

No good telling the Coroner that you sounded the horn just before the kiddy ran out.... no good someone else telling the Coroner that you sounded your horn just before the car pulled out. It might work... but one day it wont!

Sorry...

Yes but when used in conjunction with the brakes the horn is a usefull accessory !

Useful accessory?

The only use I see for the fitting of extra loud horns is that of aggression

I say again... old man or child on the pavement about to step in to the road, a car just starting to move across into your lane... the horn is no substitute for defensive riding, it will not stop you from sharing the same bit of road if the other person is deaf, or has a personal stereo stuck in their ears

So why sound your horn at all? As I said, it might work, most probably will have the desired effect... great

But one day it won't

As my old instructor said... "Never sound your horn and still have the accident"

Different opinions are most welcome on this forum. Yours appears different to some others.

Does the same logic apply to uprating your brakes?

I thought 2dB increase was double?

I get my students to ride their favourite stretch of road WITHOUT using their brakes... but on the pace! By gum, they don't half ride smoother

Nürburgring Course (2nd in group) and we were taught to ride the circuit without using the brakes... lap times only seconds slower

I get 30,000 to 40,000 miles out of my pads... so no Al, mi brakes don't need uprating!

The horn regularly makes pedestrians step back onto the pavement in enough time that I do not need to slow. If I choose to do this, yet still be able to stop if I need to, this does not make me a worse rider.

Edited to add that no-one suggested it was used in place of defensive riding, either. The intelligent and able rider uses every tool at their disposal.

Suggesting otherwise (and thinking 40k miles from a set of pads is virtuous)comes across as quite "holier than thou".

And if the horn is really loud, they leap back into the path of a bus on the other carriageway whilst clutching their chest and gasping for breath!

I used to have air horns on my VFR400. You'd get a real look of confusion as the frozen pedestrian would wonder where the invisible lorry was bearing down on them from.

The standard horn would just be ignored on a busy London street.

I find that when a car or truck is drifting into me, I move first and don't have time for the horn. If they are changing lanes slowly, than I do use the horn. A very loud horn at time that would be great. (Or it might scare them. )

As has been already said, for some-one about to open a car door, walk-out, turn or whatever. A polite little toot is all you need.



Can you give a little toot with these monster horns?

And do they just hook-up to where the stock horn is on a 1200.

Thanks

I've got the Magnum fitted to my 12GS

When I fitted it, in my enclosed garage, first thing I did was press the horn button - bad move!! Scared the sh1t out of me!

When I first started using it on the road on my commute into London, it also scared the bejesus out of me - nearly fell off!! However, recently it seems to be getting quieter - either that or I'm going deaf!!

Anyone else think theirs is getting more muted?

Apparently the Magnum hooks straight in. I have not installed mine yet as I want to fit it into the original socket, without cutting wires, and I need to make up new connnectors ending in single core wire, so that I can push it into the old connector block (very small holes, tight fit). It is not an air horn, so should still give a short parp if you need it to.

Crossing London, you make better progress with a loud horn. Drivers who you woudl have simply had to let block you in can be encouraged to move back over with a decent horn.

People react differently to bikes than to cars. You see this when you look a driver in the eye, and they still pull out in front of you. You are simply not seen as a risk, and their brain tells them it is OK. When drivers are on automatic brain mode, a little parp will often simply not register as being worth reacting to. A sound like a large car horn makes themm think they are going to sustain damage, and gets them back into lane.

And of course, at the same time, you are riding defensively.

Advocating no use of the horn is pretty similar to advocating riding in underpants and nothing else. A helmet does not negate the need to ride carefully, neither does a loud horn.

 

[Micky]

Well I never....

Oh dear Northern Boy.. if it came across as 'holier than thou' then I'm sorry... but >>>>>

To freeze pedestrians, look of confusion on their face, wondering where the invisible lorry is... aggressive indeed, so I rest my case!

As for saying that advocating the none use of a horn is akin to advocating riding in underpants....

If your extra loud horns work for you then fine, but all I'm saying is that the horn shouldn't be sounded in lieu of evasive action, so why sound it... the person may be deaf or have personal stereo deep in his lugs and not respond to your cacophony of sound.. or just be confused at your belligerant attitutude of 'get out of my way'

Personally I'd just rather get out of their way, cos it's me that's gonna get hurt if it goes pear shaped... and get on with my day, not ride round honking and papping....
