From the few reports I've seen about the Concours 14 one thing has been mentioned over and over -- a smooth engine with minimal vibration.
If the Concours 14's engine is noticeably smoother than the FJR engine the Yamaha FJR engineers should be embarrassed. The engineers went to the trouble and expense of installing the standard dual balancers called for in an in-line 4 engine. But, it may be illustrated by the Concours 14 that the FJR engineers gave us a botched, half-assed execution of the proven balancer technology.
They must have known that they'd likely never improve the balancer execution as this engine was churned out year after year. Yet they were content to offer a marginal execution of the balancer system.
It seems that Yamaha offers machines that reach about the 85th percentile. They could offer a bit better design execution but 85% is likely good enough. Engineers are expensive so Yamaha is content to offer pretty good machines but not great machines.
