UK user of this with quick shifter on my 2014 KTM duke 390, full exhaust system K&N filter, even stuck a dynojet o2 sensor eliminator on it to really get full control of fuel and ignition… after a few operator errors it all came together and all I can say is wow wow wow what a great bit of kit. More importantly, it opens up the low and mid-range and gives a bit more top end. granted it’s only a 390 but it does make a big difference in how the bike performs.. highly recommended.
