Other updates made to fulfil this goal included a new nose with LED headlight, a larger steel tank – now 13.4L with fuller knee contact, as well as a bolt-on rear sub-frame.

This joins the new ultralight trellis frame, as well as an extremely light die-cast aluminium swingarm, both of which are updated for 2017.
