A) Not familiar with any KlockWerks bars.
B) I've had the HeliBars ( HeliBars® Horizon? CCR multi adjustable handlebars for Victory Cross Models - HELIBARS
) on my XCT for two seasons now (about 14,000 miles), and think they're great.
I was looking for more pullback, and these offer as much as you can get without changing any cables (except for certain older Cross bikes -- see their web site). And I was looking for a change in wrist angle, and you get that.
And unlike any other bars, both the pullback and the wrist angle are adjustable after purchase. I've kept the pullback at max, but I have played with the wrist angle over time (and even have the left and the right sides adjusted slightly
differently from each other).
Yep, expensive, on a par with what some folks spend on custom seats (and I maintain that if you think of it that way, it's not so outlandish, i.e., what's your comfort worth, during and after a full day in the saddle?).
Also, if you're looking to have a bike with in-the-bar cables and wiring and suchlike, forget it. The pivots preclude that sort of customization.
I don't have much more trouble filling the gas tank than before. I mean, the XCs and XCTs are no picnic to begin with, in that regard. Yes, I have to position the bars just so, to get my shot at the tank, but even before things were a little persnickety.
If you're interested, I have the following two write-ups on the Helis:
1) A more general review in webBikeWorld (with a short video on the adjustability): HeliBars Review - webBikeWorld
2) A sub-gallery on my Heli install, with 50 pics and explanatory captions: Victory XCT HeliBars Installation
