I've ridden a couple of them, a '12 and a '14. They're certainly a big improvement over the Gen2 models like my '06 in terms of cornering, but they are also a very different beast. The '12 was very well set up for the rider, who was about my size, and I thought it was really an excellent handling bike. The '14 was stone stock, and needed some tweaking, but I thought it was potentially at least that good if not better.
The mass centralization does have an effect, and complicates suspension setup. On the one hand, the suspension has to be robust enough to take the entire weight of the bike dropped on both wheels at once, but also has to be supple enough to take a hit at either end without pitching the bike nose up or down as a result. The fact that the mass is so well centralized makes smaller forces more able to change the pitch of the bike, as it makes it easier to rotate the whole chassis around the Z axis. It's extraordinarily sensitive to suspension setup, but from what I've seen, the bike is not in need of any major change in geometry, like links and clamps.
It's an MX bike, though, so as far as entry to flat corners go, it has the same problem that they all have to some extent; they push because they have the shallow steering head angles required for stability at speed in rough terrain. When you look at bikes built for cornering without the need to consider extreme rough ground, bikes like half milers and sport bikes, you see much steeper head angles, often steeper by as much as 5 degrees. The best way to counter the tendency to push on corner entry is to move up on the bike and perform the corner entry using the front wheel as little as possible. "Pitching it over" or "pitching it into the turn" is how it's often described. The goal is to get the rear to steer the bike more than the front.
