Yokomo B9-302MA Motor Mount for BD9 2019 - Aluminum Motor Mount  [B9-302MA]

Aluminum motor mount for BD9

This is an aluminum motor mount designed as an RC-scale replacement part for BD9 setups. The mount attaches to the left side of the center bulkhead, creating a symmetrical feel in chassis stiffness when paired with the standard motor mount position. The construction and mounting location are intended to provide predictable changes in torsional response rather than altering major suspension geometry.

In practice the part is used to fine-tune chassis rigidity and balance. By relocating the motor mounting point to the left center bulkhead interface, riders can achieve a closer left-right stiffness match, which can influence turn-in and mid-corner behaviour on touring car layouts. The mount is a straightforward hardware swap intended for chassis-level tuning without modifying suspension pickup points.

As an aluminum chassis-level accessory, this motor mount is suited for builders who want a controlled method to balance left-right stiffness on BD9-based touring cars; verify motor alignment and spur/pinion mesh during installation.
