Of the few cages I wouldn't mind having, the DeLorean is at the top of the list. A few mods and tweaks, throw in a decent flux capacitor, and I'd be good to go (back to the future)
I've done that a couple times. First time it happened was at 1 AM on the way home from the clubhouse in GA. Went to hit the turn signal to change lanes and hit the horn instead. Damn near jumped off the bike at 60 mph.
The horn on my '16 FLHTK is louder than the stock horn on my previous bike. However, I went with after market air horns on both bikes. Stebel on the the previous and a Custom Dynamics "Mini Beast" on the FLHTK.
I've always hated the horns on Harley's. A big, powerful, loud bike with a toy sounding horn. Luckily, I hardly ever use mine and when I've tried, I usually hit the turn signal instead.
