I suspect that may be an aftermarket sourced fairing, being sold as a Suzuki accessory....kind of like how they sold the GIVI windshields for the naked Bandits and SV650 as Suz stuff in the US.
That doesn't mean there's anything wrong with the fairing....but....you may be able to buy it directly from the manufacturer....colormatched and everything...MAYBE cheaper.
Somebody may chime in who recognizes the maker.....
JMV is one euro company that has colormatched fairing lowers for the Bandit.
Here's the JMV lowers......
