Not quite sensitive enough.
I bought this lock to protect my 2005 Honda CBR600RR. The lock works perfectly as lock. It fits right in the spaces on my rotor and will keep my bike from moving. But the alarm itself was partially disappointing. It is definitely a loud enough alarm, but it is simply not sensitive enough to work properly. It has to have a lot of movement in order to trigger the alarm, which means someone could carefully be messing with the lock without me knowing. Because of this sensitivity issue, I would have rather purchased a more sensitive lock for the money or even just a non-alarmed lock for much less money. At least it will last a very long time from what I can tell. I mainly wanted the alarm as a deterrent but if it does not get tripped, then it won't deter any thieves.

Good product not quite perfect
I feel pretty safe with this thing. It'd be pretty hard to move it or the bike without setting off the alarm.

Unfortunately I can barely hear the alarm through my window (my bike is parked within 10ft of my window). I wish it was louder, but it's probably enough to spook a thief. I've also had two or three false alarms in the month I've used it. Not a big deal.

Overall I recommend it. And thank you Revzilla for your great customer service so far. You rock.

Great, so far
Heavy duty lock, the shackles are beefy but it just barely fits around a gap in my rotor. It's advertised as being extremely weather proof, it has rained a few times since I've got it and it still operates like nothing happened.

It's very easy to use, simply line up the red arrow with the red sided shackle and it's armed. The alarm has a perfect amount of sensitivity for it to trigger. I have had Xena's in the past that have gave me nothing but problems, and they're alarms are extremely sensitive and even sound if they're is a slight breeze or if it rains.

Overall a great lock so far, have had it for about two weeks so only time will tell how it continues to protect my bike.

Will this product work for the Yamaha R3?
Derrin H on Sep 8, 2015
BEST ANSWER: Yes, and if it doesn't fit the rotor the spokes on the R3 wheel will be big enough for the padlock to fit around.
Does this alarm make noise? If so, how do you shut it off?
JoshuaZ on Sep 25, 2015
BEST ANSWER: Yes it does, the alarm sounds for 10 seconds. If it's moved again it will go on for another 10 seconds, etc. Though if you move it by accident you have 5 seconds to insert your key and open the lock to shut off the alarm, which can be frustrating sometimes. There is a red arrow on the alarm to match with the shackle, you can turn it around and have the option to use it with out the alarm if you would like.
