I have the 58L Givi Trekkar Outback large pannier top box on my CRF1000D with the rubber pillion backrest which my wife likes. The top box is superb for carrying bulky light stuff around and I use it as my commuter where I may need 24 hrs worth of clothes etc. I can fit boots helmet and gloves then lock my one-pice suit to the bike with a combination lock. I can fit shopping etc too if needed. It is a slight pain in the rear view mirrors as its so big.
