Europe is next, atleast apparently. Suzuki managed to sell just 350 Cars in U.K last year... Impressive, right?:

Oh, and just so you know, their Motorcycle Industry isn't exactly 'thriving' as you put it. Say, BMW S1000R, Triumph Speed Triple 1050, Aprilia Tuono V4 or Ducati Monster 1200 costs just a grand or two more than Suzuki's GSX-S1000 and offer so much better performance and electronics rider aids like ABS, traction control, EAS, Ride By Wire, Engine Maps, keyless ignition and quick shifters etc. And Besides, most would rather have a Ducati in their garage than a bloody Suzuki! A Ducati is a status symbol, whereas Suzuki screams budget friendly.
It's only India and Pakistan where Suzukis are still selling strong (only cars, Suzuki motorcycles aren't big news even in India, use google). Partly due to: "Ma te Mehran he laisan" mindsets...
P.S Suzuki might bring a GS150 successor, who knows? And I'd welcome it with open arms if so happens provided it's a quality product at affordable price... I'd love to see them back in the game.
