One of my main gripes about it is the engine noise - it seems to get really loud at about 2500 rpm, then gets quieter above that - is that right or is it some sort of illusion?

That's because when you go faster the noise gets left behind!

Maybe the noise at 2,500rpm is the sonic boom? :lol: :lol:
