Yep, I bought a bright yellow GripLock for my LIKE200I 4yrs ago.
Use it when parking in very public places. Just to keep it from being rolled away - like that guy did with the Vespa in front of that SoCal dealership. Rolled it right down the sidewalk.
Bought one for son's Honda & R6.
Have an alarmed, pagered, Bully wheel lock for more secure parking. (Used it when at the dentist - sadly no one touched my scoot - so visit went uninterrupted )
Reading the stories told by London scooter riders....I wouldn't even try to own a scooter there.
