System is of modular design and can be assembled to meet individual requirements. The waterproof tank rucksack is secured between the base plate and the waterproof map pocket measuring 22 x 26 cm. The tank rucksack is reinforced and is closed by a roll closure with quick-release fasteners. The strap also allows you to carry the tank bag comfortably. The waterproof mapcase can be mounted on the base plate without using the tank rucksack. Fast release buckles allow that all articles can be used individually. Strong magnets secure the rucksack to the fuel tank, and a strap fixes the tank rucksack around the handlebar. Each set includes one rucksack (bag), one base plate and one mapcase. Note: Due to the strong magnets used, keep cheque cards with magnetic strips away from the base plate to avoid possible loss of data.
