Routing of wiring on frame

The routing of the wiring has been optimised to ensure the minimum obstruction.

Each section is designed to prevent interference with parts that might damage wires or cause operating failures when riding. The plates on the following pages show the origins (“0” points) for correct re-routing of wiring and the locations of cable ties.

Each figure includes references to the plates showing the wiring routing or the item to which it must be connected.
