I would say 2002/51/EC is what hindered them. 400, 750 and 1200 Inazumas were all fantastic retro style bikes built on a reliable Bandit platform. And they were only manufactured for 2-4 years before being killed by the emissions laws. End of the carburetted UJM era in all its glory. And Suzuki completely missed the retro revival too, dreaming about electric instead, even dropping GSX-R1000 because they cannot meet the emissions...
These bikes, even the instrument panels are all analogue, where the LCD gauges would fade to unreadable, the instrument panel on mine is 26yo and looks and reads like new.
Inazuma 250 is a 2012 bast*rd child of emissions laws compliance and cost cutting, it is neither a real Inazuma nor a real Suzuki. It is a Chinese bike made at a Chinese factory with a Chinese engine. It is not bad for a Chinese bike, glossy plastic on top of a heavy bike with an underpowered engine, cheap good quality bike but just not something to be proud about... Inazuma 1200 is a very different beast though.
