With Yamaha setting MSRP at just $7,990 for their new crossplane triple-powered 2014 FZ-09 naked bike, owners could very well have some upgrade cash left in pocket for the equally new S1-R full exhaust system from Two Brothers Racing. TBR says that their new system is good for an 8-hp increase at peak rpm and sheds 10 lbs. off of the FZ-09's weight which, at a claimed 414 lbs. with a full tank of fuel, is already 53 lbs. lighter than the FZ8. Two Brothers prices the S1-R exhaust for the FZ-09 at $1,189.98. See the TBR website for more information and a dyno room video with sound.
