well I might be able to squeeze the old lady for a rekluse for christmas so I've been searching for info. I'm gonna get either z-start pro or core exp (if she'll spend that much). My main question is what is the main difference between the two, Is it only the clutch feel thats different or are there more I'm not finding? are there any ill effects or disadvantages for either? does the bike still stall at times? Because everyone talks about not being able to bump start which I never do unless I stall on top a hill or something. Any more info you guys wanna throw in is good too....thanks! Anyone have one on their 2010 or 2011?
