Listing details to confirm
Listing details conflict: the title and contents list describe a 14mm U-lock, while manufacturer copy calls it a 100D lock with a 16mm shackle. Rating descriptions also differ, with one passage claiming Diamond for cycles and Gold for motorcycles and another describing the lock as Diamond for cycles. Confirm the selected kit’s exact lock and applicable ratings before relying on them for insurance or a motorbike.
