Hi. My 2018 Gen3 model was remapped with a full Arrow system on it and ran like a dream with plenty of torque, top end and noise. Just picked up a 2020 M Sport with a standard exhaust and stubby Akra can and just cant believe how flat it feels with poor throttle response lower down the revs. Even the top end doesn't feel as I was expecting. I am not particularly mechanically minded but would a full system and remap make that much difference? Surely these bikes are not strangled to this extent by the EU regulations. Any feedback would be greatly appreciated. Many Thanks. Lee
