I don't understand. Sounds serious, please explain.
All bikes sold in the European Common Market Countries have a common standard of emission controls which get stricter about every 5 years.
The present standard is called Euro 4 for petrol engined motorcycles; Euro 5 is somewhere around 2021. Cars and trucks have their own Euro standards.
The Euro 4 is accepted as California CARB compliant and therefore the other 49 States.
Euro 4 commenced on 1/1/2016 and bikes that could not comply have for pre 2016 ( Euro 3 compliant design's) 2 years to use up new production made before 2016 to 2018 and old stock in the warehouses.
Australia is getting freshly minted non Euro 4 bikes during 2018, where Europe was not. For how long, depends on US demand, due to Factory profit. 50 -100 GSX-R's a year just for Australia just won't cut it.
When 23:59 strikes that clock, those Euro 3 bikes cannot be road registered in European Countries that enforce Euro 4 emission, noise, and a myriad of other things that comprise that standard.
I've read it on line, it's an unbelievably long & complex document.
Suzuki is not alone, it applies to all Factories which want to sell in Europe. Suzuki decided the Hayabusa, the GSX-R's were not selling well enough to get a return on the technicalities of meeting the strict standards.
The V Strom's got the nod, those above died.You'll see old bikes get new motors that meet newer standards. The Bandit 1200 become gifted with a cleaner Euro 3 1250cc motor, but the GSX1400 did not.
