good first look http://www.visordown.com/road-tests-first-rides/first-ride-suzuki-gsx-s1000-review/26462.html
After a long test ride on the all-new 2015 model in southern Spain, I can tell you it was worth the wait.
No, it doesn’t have 177hp like the Super Duke R. Neither does it have a complete (optional) electronics package like the S1000R. And it doesn't look like it came from the 'Dark Side of Japan'. But it does offer all the fun you expect from a super-naked.
A big part in that is played by the silky smooth, rev-happy engine, taken from the 2005 GSX-R1000 K5 and retuned. At 143.5hp, it's got enough power to satisfy former superbike owners, especially when it's so broadly spread over the rev-range.
