Ever seen any Super bike with a crash bar? They are the most lethal of the lot and they need them the most if crash bars or guards actually were that protective.
Surf the net for the 'Hurt Report'. And in that see 39. Crash bars are not an effective injury countermeasure; the reduction of injury to the ankle-foot is balanced by increase of injury to the thigh-upper leg, knee, and lower leg.
Experts in motorcycle safety like Warner Riley have been critical of crash bars. The general consensus is that a crash has to happen in just the right way for them to offer any kind of protection. For the crash bar to be effective, the rider can't be launched from the bike during a crash. If the rider stays on the bike, though, there is a chance the bar will trap the rider under the bike, causing more damage than a bike without the bars.
And moreover I've personally been at the receiving end of multiple crashes while at motocross and other Motorsport events and practice. We never use crash bars and I still haven't broken any of my legs.
The main thing worth remembering is you wont fall of the bike in ideal conditions for the crash bar or guard to save your legs while in a crash almost 90% of the time. Mods: Sorry for going Off Topic. I think there was a thread somewhere on crash bars and Motorcycles. I wasn't able to find it on search. Please move the posts there if such a thread exists.
