Crash cage, engine bars, that sorta deal.
Would it be too hard to build?
Keeping in mind that like normal frame pucks/sliders it needs to protect the engine when the bike drops.
Also needs to (hopefully) not tweak the frame from a slow speed stack.
and not hinder normal use of the bike.

And not them big chrome round highway bars.. as awesome as they are,, not quite what im afta!
