6 foot cable w/ master lock through frame back tire and swing arm. when a pole presents itself there's even more security(i always lock forks). but i only take the cable when i might park in danger, cuz its a pain lugging it around on a naked bike. At home i use cable locke in locked garage with car parked in front of door...........and Smith and Wesson,Kel-tec,Remington,etc. etc.
