Re: Those of you who have full Hindle-929
It doesn't make the bike feel like a Gixxer1000 if that's what you're asking. The bike pulls harder and, if your map is good, the throttle and FI are much, much smoother.
I'm 195lbs and I still have to hump the tank to keep the front end from coming up in first gear. Even when I'm tucked it will still stand up an inch or two. Second gear isn't going to wheelie unless you try though.
Is it worth it? Well, I'm so happy with my smooth throttle and that alone was probably worth it. If you're wanting a lot more power go for the 1000 or the R1. Getting a full Hindle and adding 10-12hp doesn't make the bike scary-fast.
