All these bikes are all mountain, fr, dh which is how I originally described my bikes. Different strokes for different folks but if you enjoy going downhill you should give wide bars a try...if your trails allow. I only pedal to get to the top of trails to rip down them.. no xc for me.
Speaking of MX, ex pro Aaron Gwin who won this years UCI downhill series uses handlebars 780-820 wide, this man knows how to get over and behind his bike.
I know they're available, even last year I had to look hard to find identical replacement bars after damaging mine, and I realize that's what the market is asking for, so that's what bikes are delivered with.
What I'm saying is that the only thing they really do is "increase stability," which is actually just slowing the steering down. Everybody doesn't hit, or maintain high speeds on their bike. Around here, unless you're on a literal hand full of descending, gently winding, smooth trails, you're not going to exceed 20mph for more than a few seconds at a time. What you're going to do more often (around here) is lower speed work where you don't want slow steering.
