Yeah .... Same engine ( well... sort of... ), same sump.
Yngve, the exterior layout and appearance of the engines look the same to me, but are the rear footpeg dimensions, especially their length, on the bikes after 2011 the same though? They look a bit different, and I am unsure as to their measurements. (This may be critical information since the muffler support brackets that come with the exhaust systems, which typically mount onto the rear passenger footpegs, need to have the same measurements for proper fitment with the brackets)
The reason why I ask is because on most retailers, they show specific full exhaust systems (particularly Akrapovic and M4) for the 2009-2011 and the 2012-2016 GSX-R1000s.
