The TRX stock base for the clutch lever, as close as possible to the original. The distinct cylinder is for mirror attachment, not used in TRX, since the mirrors are mounted on DrSlumper's fairing bracket http://www.3dvia.com/DrSlumper/models/0DEF73031527390B

In the TRX that hole is covered with a tap, which will be shown when we start assemblying the parts.

Easy to spot is also the switch placement, a 3mm hole beside the mirror base, the switch can be seen at http://www.3dvia.com/flatform/models/61134857697B4D5F

(just revisioned it with nothing supressed and ..uuups, the clutch switch now fits its holder, haha)
