I actually bought another make 1st but you needed to have the strength of Thor to lift it , that Oxford chain is far better with a really good padlock which can be used as a disc lock as a bonus. First class chain and lock
Good Silver Grade Lock for motorbikes though a bit heavy for bicycles
Very heavy, rust resistant and an adequate lock from a reliable manufacturer.
Not gold grade... check your motorcycle insurance documentation...
Won't protect you from a skag head with 5 minutes to spare and nothing to lose.
Don't forget to oil the lock mechanism (perhaps the manufacturer should have done this...) or else it will seize within 6 months.
