2 issues to ask about 1 ) bought a small bike about 3 years ago in the name of my girlfriend, we're splitting up at the moment, it's registered in her name, but I'm looking to keep it is there anything I need to do/look out for ? 2) how common is theft of this type of bike (honda wave, honda cup etc) parked in and around BKK ie close to BTS stations, outside markets etc ? thanks
