And what's the source, brother? It's sounds like raw speculation to me, I'm afraid!
Thing with Suzuki is, it's going downhill since the American Economy recession, not just in Pakistan but all across the world. And even though the economy has recovered, Suzuki hasn't!
Suzuki has already indefinately (most likely permanently) halted production of it's automobiles in several western countries due to extremely poor reception... Have become quite an underdog among Japanese Brands, really.
I won't be surprised if PS decides to shut-off it's motorcycles division in near future... Not much unlike SNK Kawasaki! So, forget about a new Suzuki 150cc model in the stable...! It's a long shot! Truth be told...
