The Hepco & Becker Street Tourer Tank Bag does away with complicated locking systems with a practical, easy to install method. After the mounting ring is fixed at the fuel tank cap, the tank bag can be easily and safely secured with one click. Magnetic components and fixtures add that extra bit of connectivity to ensure they firmly stay in place. The removal is quite as simple as the attachment: just open the locking mechanism by pulling a cord and you remove the complete tank bag instantly. The adapter remains permanently attached to your bike.
