Aluminum engine mount is machined as one piece and today features a gear tensioner to regulate a corner gear stress more exactly. The motor mount can also be the main chassis bracing design that will link the mount, T-brace and framework for lots more flex control choices. The motor mount is made from 1 piece rather than 2 pieces (engine mount + post in previous version) to eliminated undesirable tweak also to make the engine mount more durable. The motor mount also contains the mounting provisions the battery pack backstop for simplified pack installation.
