I have the army green Roxor ...The chrome MMs to me just dont look right ,mine is for the street , off road who cares .MMs sure are cheaper .
I have the green paint, and I am not a fan of chrome as well. Easiest solution is to avoid washing it! Appearance was not even a consideration in my decision to go with mm. Mine sees more pavement than dirt too, mainly because i commute daily in it, but I have ran it through the wringer off road.
Out here in Montana I rarely use 4wd since I installed lunchbox lockers, and everything offroad is hard, just uneven. I took it to Michigan this summer and it probably spent more than half the time there in 4wd since its all sand and mud, and vacation meant playtime instead of commuting.
I'm still running stock tire size, and probably always will since it maintains a reasonable center of gravity, and I am yet to be held back by anything besides 3' of snow. You would be amazed at the sand hill climbs it can do with lockers and aired down tires. I sure was!
I'm confident the mm hubs will last forever with stock tire size, are far from being the weak link when running bigger tires.
If looks and on road drivability were my only concerns, I'd keep the stock hub flanges and ditch the front driveshaft. In my opinion the roxor is too much fun on the trails to keep it on pavement.
