And all racing ECU and increased RPM - at your risk. You can reach 175-180 RWHP, but not for long. The engine design and the materials are not intended for this.
Not the first time I read about broken engines in any races and when using racing exhaust and racing ECU. Therefore, I use my bike in stock exhaust and ECU. I also often run on high RPM and don't want to change engine every 1000 miles.
I don't race and don't ride on track on my 1190. Just street riding.
