powerparts

Hi. I was thinking of buying a FS 570 but now i read that the power parts is no longer available. That its out of production. Is this true? I mean that's one of the biggest reasons i want husaberg. because of all the bling :) And it doesnt cost as much as a ktm.

there is an O-ring chain on my bike, but what is it's advantage compared to a normal chain ? also, in my manul it says that you shouldn't lubricate the chain when riding in mud ? :? and how about the mapping switch ? when i bought the bike they used this mapping switch as an argument to buy...
