Top case Givi have a good range of cases of all shapes & sizes. I chose the E350 with rear brake light. A medium sized case with large reflector and good quality, it can take a full face helmet, boots & jacket with careful packing. OK it may spoil the classic lines of my machine but, it is great to not have to carry helmet etc. around with you.
Indicator warning device Motorcycle accessories shop Hein Gericke stock this useful lifesaver and can also obtain Givi & Ventura accessories.
Alarm from Datatool is a compact 2 type and fitted 'only just' as space for any accessory is at a premium.
