It's in the details
The most obvious difference between the 2012 Suzuki and its predecessor is the single-muffler exhaust that replaces the dual-muffler design adopted back in 2007; it's been a long time coming, but we're glad to see the old, unwieldy exhaust go out the door. The reworked system is new from front to back, with a stainless steel header pipe matched to a shorter titanium muffler that exits the right side of the bike. Pipe length and thickness have been optimized, with the biggest benefit being increased midrange power, claims Suzuki. Weight-conscious engineers have also removed the large under-engine chamber that made the 2011 model's exhaust so heavy. All told, the 2012 GSX-R1000 is 4.4 pounds lighter than its predecessor, and much of that weight savings is owed to the new exhaust system.
