If you can read french, you can read the investigation of french motorbike magazine. They asked me to pick their own anti-theft Abus Plus and Abus X Plus put on their own Motorbike in a street (like in real life). And they timed me. I wish you a good reading http://www.test-serrures.org/moto-jou...
I picked the tops of Abus Granit X Plus : The Abus Granit Extreme X Plus 59/180 HB 310
It's very, very, very expensive. And yet, it's easy to pick !
I love Abus Plus and Abus X Plus, It's a pleasure to pick them !
