Yokomo B9-BW20A Center Balance Weight (20g)  [B9-BW20A]

Center balance weight for BD9

This is a 20g center balance weight designed for RC-scale BD9-style setups. Installing the weight at the chassis centre lets you change overall mass distribution without upsetting left-right symmetry, making small tuning adjustments to balance and handling easier.

Intended role: place the weight at the vehicle’s central mounting area to shift the centre of gravity slightly forward or rearward depending on placement, which can influence pitch and transient response during acceleration and braking. Because the weight is a single 20g unit, changes are incremental and suit fine-tuning rather than major layout changes.

Compatibility is limited to the supported chassis listed below, so confirm fitment before modifying your setup. This part is an RC accessory intended only for model chassis use.
