New motor is of interest as to power/performance. Appears HD now has a better power plant than in the past, from the numbers posted. Marketing info says is "cooler" engine. Would like to try that out to see, test rides will tell the tale.
Colors are ok/very good from what I have seen on the CVO SG & Limiteds, to me are an improvement over the past several years.
Engine upgrade HP/TQ options should be more than interesting since the base starting point appears to be greater by a good margin. Aftermarket options - headers,mufflers, breathers, tuners, cam, etc. - lots of changes.
Not much else has changed unless I missed it. Maybe suspension improvements?
In 2 weeks, after people have seen the bikes in person, the comments on colors will be different from those who have seen them. Bikes need to be seen in person, sunny day or well lit. Pics never do them justice.
