I'd say about 90% of the guys there have bikes and ride them.  Some of them are still in the 85/150 class, but for the most part, everyone rides.  MX Simulator is a hard-core game that you will really never be good at unless you ride for real, or put in 2x as much time as anyone else.
But of course, none of them have ridden this bike (neither have any of us, as far as I know) and I can only name one guy there who's ridden an older Maico.  His username starts with a J and ends with an ETZcorp.  I'm sure there are others who've ridden them, but it's crazy-rare.
Also, they weren't all so negative.  I took all the negative bits and compressed it into that post.  There was other feedback to be seen.
"Looks kinda cool tho.But still looks like 2000 years bike."
"... That said, I wouldn't pass up the chance to ride one."
"Just wonder.You riding at the track,jumping whiping and stuff,gangsters shows up,they shoot into you,bulet hit aluminum gas tank,spark comes out and BAM! Explosion!  That would not happen with standart plastic gas tank."
"I cant understand left hand kick starters."
