BD9 Mid-Motor Upgrade Kit Compatible with Yokomo - JR-BD9CK by Jazrider  [JR-BD9CK]

Details of the BD9 Mid-Motor Upgrade

This mid-motor upgrade converts the Yokomo BD9 touring car platform by relocating the motor from the rear to the middle of the chassis. The change aims to offer a different handling envelope for racers who wish to tune balance and rotational behavior for circuit performance.

The kit concentrates on the mechanical connection between the motor and the BD9 drivetrain, supplying mount features and alignment points so the motor sits correctly relative to the gearbox and spur. Intended strictly for scale RC models, it does not apply to road-going vehicles.

To fit the kit you will remove the original motor mount area and install the conversion hardware to the BD9 chassis. Check gear mesh, motor height to spur engagement, and electronics clearance during the installation process. The kit suits those comfortable with basic drivetrain setup and chassis modification.

As an aftermarket option, this mid-motor kit lets BD9 owners experiment with center-mounted motor dynamics to change weight distribution and handling without swapping chassis platforms.
