Just because you have a cage doesnt mean your bike isnt going to be totaled. If you go down at a high speed with a cage i can almost guarantee your frame will be fucked. Puts alot of stress becuase of it being bolted to frame.(thats why you see so many stunters with welded frames)

Look at the stunters bikes.... cage wont save everything.... the bike usualy flips a few times.
