570 XMR vs 570/570 LE clutches/speedometer ?

I tried looking through parts diagrams but I can’t find any information on whether the clutch weights/primary/secondary springs for the 570 XMR are different from the 570 LE or standard 570L models. I have a 570 LE and am considering switching to 28" tires.

Also, is it possible to have my speedometer re-flashed to the XMR calibration at a dealership? My speedo is currently dead on with my 26" Bighorn 2.0s and 27" Zillas (they measure 26" mounted). If I go to 28s I want my speedometer to be accurate for maintenance and riding trip/trails information. I’m aware I can buy a speedohealer if I get 28s but a re-flash seems simpler.
