Zldrider, if you want more height than the Helis give you, you won't get it from the GenMars by themselves. The Helis raise the bars 1 1/2" and are 1/2"wider and 1/2" farther back. The GenMars are a plate which fits under the bars and raise them 3/4". I have both, have ridden with both, one at a time, and am now running the GenMars under the Helis. Someone else around here came up with the idea, and I thought I'd try it. Been riding with them for a couple of weeks. Gives a total of 2 1/4" raise which I like, but the GenMars, unlike the Helis are very noticeable, and leave holes around the suspension adjusters, plus they add probably a pound of weight up high, while the Helis look stock and weigh the same as stock bars.
The installation of GenMars under Helis is a bit tricky also. Had to get more slack for the upper part of the front brake line, and move some wires and cables around. It all fit, but just barely. Then had to trim the lower edge of the ZG Sport Tour screen for clearance. Works fine, and if I was going Iron Butting I'd definitely consider it. I'm putting braided lines on the front, so I'll get them a bit longer to return the slack to original specs.If anyone does this mod, I recommend doing that.
My only gripes about the mod are that I think the GenMars are ugly and add weight up high. Bikes have a way of gradually gaining weight like most riders. With this bike I've really worked to keep the weight down. I'm still not sure if I will keep the double setup, although it is comfortable.
