I have the givi bars, cos I reckoned they had the highest protection.
I have a bash plate from a bloke in the states, but I know the swmotech one fits, but if you need it in anger, don't get one that has holes in the bottom, that's just daft.
They nearly all fit using just a clamp to the bars, so almost any could be made to fit easy enough, without special knowledge or bits.
Photos of mine, all over the gallery here I reckon.
