Hey,

Can anyone tell in detail what changed (if changed) in the engine from 2009 to 2012 both in the 450 and 570 modell?

Thanks
 
iirc compression was raised in '10, and the oil sight glass is bigger on later engines, also a new fuel pump (this was a warranty replacement item)
 
Hey Anthon, thanks!

Anything else? What is the max rpm of the 450 and the 570? Tried to google it..didnt find an answer..

I've seen some dyno graphs that have an implied RPM, don't remember the actual figure, hmm maybe it's worth to try a google images search for "570 dyno site:husaberg.org" or similar

I seem to think I saw a cam auto-decompression change being discussed also, very recently iirc? if you haven't seen that then that's also a hint for you :) heheh, my apologies for these vague answers
