Don’t know where the ‘no Charger’ comes from. The new Pikes, OEM or not all have the Charger damper as far as I know and I’ve seen zero evidence that they don’t. Mine (OEM RC) certainly do, people have opened them to prove it, and the switch on top says “charger”!
The difference between the RC and RCT3 is the RC does not have the pre-set options on the switch. It does have adjustable compression in clicks which achieve the same result just you have to work out how many clicks to turn to get the setting you want, plus at one end it becomes a lock out. If you are the kind of rider that sets and forgets about it, the RC is all you need.
With the OEM, some (or all) of them come with a cheaper finish. Gloss finish and stickers for decals instead of the diffusion matt and decals under the top coating.
The RC will become available after market in 2015.
