The C14 handles great. Very easy to carve into the turns and very fast in the straights. Your feet are a little higher and a little further back. Not uncomfortable, just a little different. The engine also like to be up higher in the RPM range. I can't remember the exact red line, but it is somewhere north of 10,000. The bike seems to come alive above 5,000 rpm. The gearing is very nice and it does have an interesting Over Drive. 70mph = approx 2000 rpm. There is no power in OD, but the mileage must be great. The front brakes are very strong, but they come on a little too quick. The rear is average at best. The suspension is real nice. The bike tracks all corners real solid and quick transitions are fluid. Compared to the FJR, the cornering requires a little more effort, but not by a lot. As far as the weight goes, it feels heavier in parking lots, but once under way you don't notice it. It does have the least wind protection of the group. You can actually feel wind on the top of your legs.
As a C14 owner with 7500 miles to date, I have a slightly different perspective on a couple of issues. First the heat...yes, the C14 has a heat issue that is caused by the 4 into 2 into one header system (that has 2 small cats) that runs under the right side of the engine and dumps a lot of heat on the riders right leg. It is noticeable at 80 degrees, annoying at 85, and gets pretty hot by 95. I don't notice the heat on my ankle because of my boots but my calf gets pretty hot...one solution is to wear riding pants that will insulate you from the engine heat...my solution is to park the C14 and ride my 2008 FJR. The C14 does not have any heat issues with the left leg or the tank. It does have really good leg protection from wind and rain (which also holds in the engine heat) and it is possible to adjust the stock windshield so that wind is routed across the top of the legs.
The C14 has a shorter engine stroke than the FJR and almost begs the rider to rev it to its 10,500 redline. The power below 4,000 rpms is not impressive unless you remove the secondary butterflies or add a TRE and then it is very impressive.
Sixth gear has very tall gearing, 70mph is actually about 3000 rpms but if it improves gas mileage I have never been able to verify it. When I take trips with an FJR rider, he will usually take 10-12 percent less gas than I do, and I have to fill the C14 with premium. Sixth gear is nice for high speed cruising but I am just as happy with the FJR's 5th gear.
The front brakes are very strong and I like them that way but its probably a good idea to spend the extra money for ABS if you have to ride in the rain more than a couple of times a year.
The suspension is firm but the forks need a compression damping adjustment to be as plush as the FJR. It does seem to be dialed in pretty good for high speed riding.
The C14 has more ground clearance and lean angle than a FJR but carries its weight a little higher. The FJR is a little easier to ride through a corner but the C14 has more potential and you are less likely to drag hard parts.
I really like both of them but if I could only have one it would be the FJR.
