2011 Kawasaki ZX10 vs 2010 BMW S1000RR on a couple top speed 2nd and 3rd gear roll-ons runs. The ZX10 has a Akrapovic slip-on with mid pipe and flashed ECU by Guhl Motors. The bike wont pull 6th gear with stock gearing to red like it does in 1st thur 5th. Im guessing the speed limiter is still there and/or the rev limiter. The BMW S1000RR has a full race Akrapovic. ZX10 rider is 6'1 about 235lbs no gear, BMW rider is about 5'10 at 220lbs no gear. More info at the end of the video. For my ZX10 I sent the ECU to DP Tune. Results to come soon.
