Kovix KNX6 Steel 120dB Siren Disc Brake Lock 6mm Lock Pin IP67 Waterproof Motorcycle Security Fluorescent Orange

It's easy to use, small enough to not look terrible on your parked vehicle and sensitive enough for me to set this thing off a minimum of two times a week lol. Would love to see other colors though ,maybe a chrome plated one that would complement my bike. I'm used this on a 2016 Harley Davidson street 500 and a 2019 Harley Davidson Road King classic

Ninja 400 won't fit the smaller round rotor holes, but goes though the larger "smile" shaped route. All in all if you even tilt the bike up its gonna be a bloodbath. Did it in my garage on accident and woah...

The alarm has stopped functioning. I changed the batteries and when I lock it, it does beep to let me know that it is alarmed (long beep after lock). But when I move the alarm, even slap it around, it does not sound the alarm. I'm giving it 2(not 1 star) stars because at least the lock still works. Not worth the extra money because cheaper locks are out there.

The media could not be loaded. The first one this was broken it just wouldn’t work. I couldn’t get it to pop up the second one that y’all sent perfect so far it works great. It’s like the first one you sent didn’t have the battery didn’t have the Allen wrench and by the way, you need a longer Allen Wrench

The media could not be loaded. After few hours of locking the motion detection stops working. No matter how much you shake the bike or the device it doesn't beep
