I personally think it was just time for Suzuki to create a naked bike that could compete in botb performance and sales with other manufacturers, not just BMW. Suzuki is also competing against the bikes like the Kawasaki Z-1000, Ducati Monster 1200 and to a lesser extent the Yamaha MT-09. (I say 'lesser extent' as i dont see the mt-09 being in same league as the other bikes mentioned and it also has a smaller engine capacity).
The BMW offering is a nice bike, but i dont see how its better than the Suzuki or even the kawasaki, and insurance and registration on the Japanese bikes would be far cheaper not to mention the price difference of the initial purchase. Japanese bikes = great package at a good price Euro trash= about the same as japanese quality + 10k + lol
