2 PCS Motorcycle Helmet Lock & Cable, Multifunctional Helmet Lock & Theft Deterrent Cable, Tamper-Proof Helmet Lock for Motorbike Scooter Bike, Motorcycle Accessories

Using this on a 2015 Triumph Street Triple.I could not use the entire rubber strip, as it was too crowded, but I was able to cut off a 3/4" piece for each half of the bracket. Also the adhesive is weak. After that mounting was pretty easy.I've only used it a few times, so no opinion about longevity, but the shackle snaps closed firmly and the key works smoothly to release it (I've read reviews where these things are problematic). I also like that it's totally inconspicuous, and the open shackle can't hit the tank.Obviously the shackle culd be easily cut with bolt cutters, so I wouldn't leave my $600 Shoei attached to it for a long period, but it's fine for trips to the store, the gym, even work (for me anyway, as I work in an office in an upscale business park).For me this is an item of convenience rather than security, and for ~$8 it's exactly what I expected. I accidentally purchased the one including the cable, which I'm not using, but it might come in handy at some point, though again, it too could easily be cut if one were so inclined.
