Word of warning if thinking of a system 5 helmet (got one and great helmet). It will not fit in to ether the system or adventure alloy panniers! Just tried it. Wont even go halfway in the alloy boxes. Tried several ways but can`t close the lid on ether of the system panniers. So have to ether chain it to the bike or lug it arround with you. Not sure about the 1200 expanding type. Just somthing else to think about when buying.
