i had a 2005 hayabusa stolen back in august. i had the bike for 2 weeks before it was stolen and regret that i did not have insurance on it. so i have to pay for the bike so some low life can ride it. there is a video on youtube of some guys breaking in a motorcycle shop and within 10 minutes had stolen 7 or 8 bikes and were gone. 4 guys can easily pick one up so the lock is pointless there. so yeah i think something like lo jack would be a great investment. the guy that thinks the lock is enough obviously hasnt had one stolen....
