Triumph crash bars are kinda odd looking but look like they would be most effective if you tip the bike in that they give some angle to get under and lift it back up. The aftermarket case covering ones look like they would protect the engine better at speed. I personally have the LSL crash bungs on mine, The are not as obvious as others and would provide some case protection in a skid.
I'll post some front and side views here, but they're from a distance and not detailed for that item. I'll get some close ups later today and post.
