2021 F3 Limited Horn upgrade

[2katz]

I’ve been researching horns to upgrade the puny horn on my bike. Everything I find notes they fit pre 2020 model's.

Two questions:
- Is there ‘that’ big of a difference in the current model vs. older, that would keep a horn from being installed? It already appears that I would need to relocate.

- I do want a two tone horn. I don’t see much of a difference (sound, physical appearance or reviews) between the Wolo Big Boy and the Stebel Nautilus Compact. Is one really better than the other and/or is the another manufacturer I’m missing entirely?
While a train horn is an option, I don’t like how far it would need to be mounted off the frame to clear the panels.

Once again, thanks for your insight!

I ‘think’ this is the last upgrade for awhile. After I install a few items coming in this week and the horn, I’ll update my signature, noting all upgrades and include a photo.

Which ever horn you get, be sure to use a relay. I added a fuse block to attach all electrical accessories to avoid the bike's fussy electronics. Here's a photo of my dual car horn installation on the back wall of the frunk, above the battery. Note the fuse block between the horns.

Thanks for the reminder re: the relay. Hubby says I really need one to ensure the horn can reach it’s full potential!

Try a search here for: Horn Upgrade or WOLO Horn. Lots of info!

That, and not melt the switch.

I installed a set of goldwing horns in the cavern under the frunk liner. Got them for less than $20 off eBay. Had great result with that. One must be aware that the OEM horn is switched by the ground wire, the hot +12v is always hot with the bike on or off. I'm showing the necessary circuit diagram for using a relay to beep your extra horns (if you are not going to run horny strobes ignore any extra wires not hooked to the horns).
