The TFS system is designed to simplify the attachment of bags to plastic tanks, which, unlike metal tanks, cannot take advantage of the convenience of magnetic attachments. It consists of a sheet of eva-laminated polyester coated with non-slip pvc that, once attached to the motorcycle by means of 4 adjustable straps, forms the fixed base for quickly attaching and releasing the bag from the motorcycle. The measurements of the TFS fit most motorcycles on the market, and the system allows the attachment of all tank bags of our production, with the exception of Tanklock bags.
