"Mmmm, 146 hp crank rated, mine made 143 on EBR's dyno in 2010 and it was the highest except for their full race system at 145 hp, that was $1800 + a programmable ecm at $750 back then. The HMF made 138 as I recall. That said, an RX/SX makes roughly 40 hp more than an 1125 when comparing stock numbers. Best I've gotten out of an RX to date is 179 at the wheel. Several others around the world have hit 177 & 178."
The guy I bought the 1125 from claimed EBR told him that the FMF and EBR race computer makes 153 crank, I have no idea if thats true, but if it were rated 145 stock I don't see that being an outrageous claim. Either way I love them both, and my XB12X and the XB9SX, those are for different riding situations.
I've already checked your stuff out and most likely will be purchasing a set up for the 1190 before to long ! I personally like the look of the stock system, but no bark like that FMF has, I need that...
