Eh no. Noise reduction might be a by-product of a regulatory requirement to reduce power for the French market, or the marketing requirement to differentiate the -A from the -R in horsepower terms. Period.
Why don't you review the maps and look at where the secondaries differ in position? Noise regs are focused at 2/3 gears at relatively low RPMs. The secondaries rein in HP at high RPM and close to WOT on both the '09 and '10 ADV-A and the French market Supermoto.
