This is an XRAY T4 2017 Aluminum Motor Mount. This CNC-machined motor mount is made from premium Swiss 7075 T6 and is part of the left layshaft bulkhead to eliminate unwanted tweak. The motor mount is connected to the chassis by 2 screws under the layshaft, and features the mounting system in front of the motor.
The motor mount system consists of a motor mount plate that is connected to the motor mount by a button-head screw (which is more tweak-free than the previous countersunk screw). The motor mount plate is connected to the chassis via an M3 nut, and an extra countersunk screw can be placed ahead of the nut if more reinforcement is needed. The nut can be removed and 1 of 2 holes behind the nut can be used for more flex adjustment options.
