Hi patches,
The Coolant expansion bottle is located on the left of the bike at the front.
It can be seen, and the level checked, by looking inside the front wheel arch.
Removal of the side infil panel ( 2 bolts and pull away from rubber grommet )
gives access to the Expansion bottle cap.
The upper panel has to be removed before the Side panel -
( 2 bolts, slide forward to release and undo the electrical connection for the air temp sensor ).
The overflow pipe is routed to the left side of the bike,
roughly in the middle, down near the side stand
