How do our old Italian Huskys compare to new bikes?

I used to have an e-start 2004 Tc-450. Heavy-ish and slower turning plus stock carb was a pain. My Husaberg 570 feels much more nimble and lighter than the old TC-450 even with all the stuff I have on it. The 2012 TE310 is best handling enduro bike I've ridden. EFI is decent but took a good bit of sorting to get it right and gearing kind of sucks for dual sport use but that's not it's strength. It's magic in flowy single track and still has good power at elevation in the Sierras (with revs). edit - EFI sorting included changing from TE to TC box and made a huge difference.
