The Stebel Nautilus is very loud but needs a relay to pull the juice out of the battery direct, comes in a variety of colours....ebay
Stebel Magnum is also quite LOUD and will happily just plug in in place of the standard horn with no other electrickery needed..
Yeah... hahaha Anth!!! Just spent fruitless half hour on t'interweb....... apparently Stebel don't make that model now. Stebel site quotes a TM80, but does not say whether it will fix to a Ducati.... ??? Anyone know???
Might only be an issue with CanBus bikes, but I fitted one of these to my MTS 1200, and it needed a relay to get it to work - the power to the OE horn wasn't enough. Worth the effort though and not difficult to do...
Ah - didn't know that - been a while since I fitted mine. Being an ex BMW rider I got mine from Nippy Norman, and a quick look on his site showed up this one; Not as loud as the Magnum, but still better than OE, and looks like it would be easier to fit too - may not even need a relay?
anyone tried the Denali canbus compatible horn? Denali SoundBOMB Mini 113dB Horn Compatible with all CANbus electrical systems | eBay
