Ah boy, this one cost me, in pain ...
I mounted up a new scotts stabilizer to my '13 WR450F (which, I love both BTW, the cycle *and* the stabilizer, two great pieces of equipment).
Well, the cycle comes standard with a tapered handlebar (tapered fat to thin), and a bar protector (what looks like styrofoam, covered with a thick plastic graphics mount cover).
I took the bar protection cover off, mounted the stabilizer, and then went "huh, does not look like I can get the pro back on, guess I'll leave it off..."
I tend to not ride well, yet, in the attack position. I'm crouched too far down, too low, over the top of the bar. I like the position, but I paid the price for it now.
I smacked a big rock, and the cycle popped up into my chest. Boy Howdy, that bar clamp hurts... I mighta cracked a rib, I'm not sure. It's a week 'n a half later and it still hurts, but there absolutely no bruising, so I'm waiting it out.
I need to figure out how to retrofit some bar protection up there, over the new stabilizer.
I'm writing so: Dont you make the same mistake.
