A CLM handlebar lock blocks the handlebar of your scooter and makes it a lot more difficult to steal it. The bracket holder for the lock is mounted under the buddy seat. The lock itself is just outside your buddy just below the edge so you lose no space in your helmet compartment and still the lock can be used easily. A pen is mounted in the handlebar which connects to the cable if you lock the scooter. Because the cable is just long enough, it's impossible to turn the handlebar and your scooter is a lot harder to steal.
