As mentioned, securing your motorcycle by means of a chain lock is the best protection against theft. But what if you don't have anything in the garage or on the street to attach your bike to? Ground anchors are solid metal brackets that can be mounted in walls or on the ground. Some ground anchors can be mounted using brackets and bolts, others will need to be recessed into the wall and secured with cement. Pass your chain lock through the ground anchor for the best protection against theft. Which ground anchor is best depends entirely on where you want to mount the ground anchor.
