What bar setup are you running? I'm fairly confident this is the reason why my steering is heavy, which I don't mind by the way.Yes, I believe it's a pretty necessary upgrade and i'm getting one for mine as well. I was surprised by a pretty gnarly tank slapper the other day doing 85 mph on the hwy. I was able to get it under control, thankfully. I also get a lot of wobbling in the turns when I'm attacking them hard. My steering isn't heavy at all.
