Good sturdy chain and lock, came with 5 keys, bought this to use as an extra lock on my E bike so I carry 2 locks, the chain is far more versatile and flexible than my other lock and chain is long enough to loop round most static anchor points like barriers and lampposts, the cover is quite good quality and stops the frame getting marked, haven't had it long so can't really say how long it would last, its perfect for my pushbike and not too heavy to carry, you would probably need the more heavy duty one for a motorcycle but this does me fine.
