Abstract: A motorcycle lock consists of a housing containing a lock in an intermediate portion and two deadbolt bases in two lengthwise ends, two deadbolts on the deadbolt bases, an upper rotatable disc on the lock and a shackle. The shackle has two feet able to be inserted in two shackle holes in the housing and coil spring holes in the deadbolt bases and then separately locked by the deadbolts by rotating a key inserted in the lock. In unlocking the key is used to rotate the lock to free the two deadbolts from the two feet of the shackle.
