This [url=http://cb1100forum.com/forum/showthread.php?tid=11007]<< POST >>> sparked my curiosity regarding what, phyiscally, changed internally...so I did some digging....
This cross section shows the big changes are:
the new 2 way valve + the base T shaped shaft.
The parts catalog doesn't show the 2 way valve as a separate item, so I'm guessing that this valve is fixed inside of the bottom of the chrome fork tube. And the different part number between the 2017 vs. 2013/14 fork tube appears to be the case.
I did a quick comparison between parts needed to upgrade to the dual bending feature, and it appears that these 4 are basically alll that's needed.
Those 4 parts (~$200) cost 50% of a complete fork.
-------------------------------------------------------------------------
Note, the 2017 fork also has different part numbers for the main spring, spring spacer, & top cap w/ "dual bending" scribed on surface. But, imo, they aren't necessary items to convert to dual bending.
When my time comes to mount a new front tire, I'm seriously thinking of installing those 4 parts.
or, I might just do what pdubs did and get the whole fork instead.
Having choices are good
