Other than possibly bragging rights against BMW's K1600 and maybe help those who routinely ride two-up with subtantial luggage, I don't seem how the extra cc's would make a difference for most C14 riders.
I don't recall ever venturing into the upper 1/3 of the RPM range, which is where the '12 ZX14R makes its magic. I spend 95% of the time below 5k. As a sport tourer, the C14 could always use more refinement (NVH, MPG, wind/heat management, instrumentation, seat, luggage, handling, fuel mapping, TC, etc.), even though it already does very will in those depts. I'd rather see Kawi focus on those areas than adding more power.
I'm sure the 1441cc will replace the 1352cc sooner or later, as it makes no production efficiency sense to keep two very similar engines on the same production line.
