Silly premise to this thread. I'd be "embarrased" if I started it.
Two points:
First, we don't really have any back-to-back experiences that say, on average, the C14 is significantly smoother than the FJR. The early reports have been mixed - some saying it is very smooth, others saying it buzzes pretty good at certain RPMs. Let's wait for the first comparision tests before lashing out like this.
Secnod, technology always get better and the idea that any inline-4 with dual balance shafts, if properly engineered, should be just as smooth as all the others is a total crock. That's like saying that anyone who has produced inline-4 car engine for the past twenty years should be "embarrased" if they haven't matched the power output of Honda's latest VTEC wonder. The C14 is a six-year newer design and in these six years materials, metallurgy, computer modeling,machine tools, etc. have all improved. As well, it incorporates some innovative new features like VVT and the new shaft drive which change the vibration characteristics. Even the way the engine mounts to the frame can have a tremendous effect on perceived vibration when you're dealing with bikes as basically smooth as the C14 and FJR.
All bikes are compromises between literally thousands of factors. The Yamaha struck a great compromise back in 2002 and it appears the C14 is striking a great compromise now and since it is newer, it probably is going to be improved in a lot of areas, perhaps vibration is one of them. But the idea that Yamaha dropped the ball six-years ago is patently ridiculous.
