Amazing and many aspects they are rated same or better but I like you not sure of longevity and reality of a ranger with weight on it every day with small clutches sloppy rear suspension. All upgraded before they get to site I reckon. but they mines may well regret the complexity they end up with with all the electronic.

yeah I wondered that and was thinking same rotor and different size pads or differing pressures. I will do some more reading. I am wondering is version 4 is a modular or just a version number for all the updated design and they simply use the required size. Without heat changing braking ability size can be pretty compact and very powerful but more i think about it unless they are using multiple adaptor brackets they must be casting each version.
