Messages from sbk

SBK appears to be a service, app or website that sends SMS messages containing unique codes. The recipient is instructed not to share the code with anyone else. A web search reveals that SBK could stand for several things such as Self Calibrating Underwater Breathing Attire and Single Canister Underwater Breathing Appliance; however, it seems more likely that in this context, SBK refers to Superbike World Championship - a road racing series based on heavily modified production sports motorcycles. It's unclear how these two concepts might be related though without further information from the sender of the SMS messages themselves.
