leather mounting plate for Click quick release system and pair of correct combination locks.These panniers seem to be very rare (I’ve never seen another set) and have always attracted attention and favourable comments. My best calculation measures them at 16 litres each. i.e. 32 litres total. I have had them fitted to my Harley Sportster by the leather mounting plate going over the rear fender beneath the saddle and the bags then easily fit by the quick release lockable Click system. I imagine they can be fitted to other models in the same way.
