We require high quality and durability, that's why we use an automobile part company to manufacture our PREMIUM bowden cables. Similar PTFE-cables are used by General Motors and Mercedes in their sliding sun roofs. The cables are made of polysil, polyethelene and silicon oil components. The technical term is PTFE. The word "teflon" cannot be used, being a registered name from Dupont: https://en.wikipedia.org/wiki/Polytetrafluoroethylene

All PREMIUM cables stand out through their ease of use and long durability. The small frame set kit has been increased to include 2 choke cables and 2 gas cables to cover more variations.

Note: Since the PX 98/MY/11 models come standard with a hydraulic Disc Brake on the front, the front brake cable included in the kit is not needed for these models.
