    Aftermarket Horn

    Anyone recommend a good, loud aftermarket horn for my GS650G?

    I mounted up a pair of the Fiamm Freeway Blasters.

    Most aftermarket horns that are louder than the stock ones (in other words ALL of them) will draw more current. Recommend putting in a relay - existing horn switch powers the relay, the horn current comes direct from the fuse block.

      +1 on the Fiamms. One of the first mods I make on new to me bikes as they've saved me being merged into a couple of times now. they come in a High and a Low tone models so mount one of each. They are not overly expensive at between $10 (on sale) to $20 but if price is an issue even mounting just a high tone makes a big difference over stock.

        I did this with the headlights on some of my cars and it made for a visible difference in brightness, it's one of the things I plan to do on the GS once I get all her missing/damaged bits replaced/fixed. I can definitely see how it would make sense to do it for the horn on a bike, considering the relative fragility of the electrical system.

          What about hardware? Do I need anything or does it mount where the stock mounts?

          Thanks!

            They're larger than the stock horns, so may or may not fit in exactly the same spot. I've got mine mounted on the Vetter bracket.

            Each horn is a single-bolt mount, so not too tough to figure out alternative locations.

              These WOLO Bad Boys can be found at Harbor Freight, I forget how much it was. This one is mounted to my sold '81GS750L. Yes, it's loud !!!

                What 850GT said, I installed that horn (high note and the relay) very loud, very good. Easy install.

                  About $40, IIRC.

                    I'd go with the Walo Bad Boy. Use a relay to hook it up. Very loud horn.

                    Where in Baltimore are you located? Maybe we can go for a ride sometime.
