Funnily enough, I just fitted my used (off my 2015 Triumph Tiger sport 1050) Denali Soundbomb mini onto my 2019 Tracer gt900. Took almost 4 minutes. Would have been slightly less if I'd known the mounting bolts were 10mm and not what I thought were 12's..... It's definitely plug and play, turned on my ignition, quick blip of the horn button and the familiar breathy honk greeted me! Well worth the upgrade even if it's not massively louder, it is definitely a different tone that gets the attention of, well, everyone!
