will parts from an older bike fit the 2017 model , for example gilles rearsets, asv levers, power commander 5, hrc quick action throttle, these would all be taken from a 2012 anniversary model bike
Taking a guess but the levers, rearsets and QAT should swop over! Power commander you'll have to wait and see
The Qat might not fit given that the new version is ride by wire and the throttle tube will be different.
