As a bloke who has managed to gently deck his bike three times, can't see the point in the extra iron.
Might be different on the move but if you drop the bike while stopped (Eg get of thinking sidesand down, my excuse 800kms and very tired) then the rubbers stop it all.
Now been over on both sides and not a mark on mirrors, bars or panniers. Last attempt was with all boxes full of luggage on the Adelaide trip. Had the side stand down while waiting for Wellington ferry and when rode onto ferry just forgot I had moved and stepped of the bike, kabang. Lucky the pillion had already got off.
