This blue aluminum rear suspension mount is intended for the front-side location of MR-4TC BD style on-road rear assemblies. As a separate metal replacement, it takes the place of the standard front-side mount to offer a stiffer, more consistent interface than molded parts.
The BD-300MRF is engineered to limit flex where the swing arm attaches, helping to stabilise rear geometry and maintain handling balance. Install it at the front attachment point of the rear suspension and confirm fit and clearance during installation checks.
Ideal for hobbyists seeking longer-lasting, repeatable components, this part is compatible with MR-4TC BD style rear layouts and supports precise setup adjustments for on-road performance.
