This is an RC-scale rear wheel sold under the Yokomo part number YOKB4-827, designated for the BMAX4 III rear positions. The bright yellow finish is intended to make identification and inventory handling easier in a busy pit or workshop, while the form factor is for 1/10 off-road use.
Compatibility is limited to the model named in the product title, check your parts list before ordering to confirm fitment. This wheel serves as a direct replacement part and a basic tuning component where wheel color or replacement condition is the priority rather than a change in geometry.
Installation follows standard 1/10 rear wheel mounting practices, using your existing wheel hex and retaining hardware. When fitting, ensure the wheel seats flush on the hub, torque fasteners to the values recommended by your chassis manual, and rebalance the wheel if you notice vibration after mounting.
Tuning role: swap this wheel only to change cosmetic identification or to replace a worn or damaged item, combine it with tires chosen for your track surface and suspension setup, and verify handling on a test run to confirm no unintended changes in roll or traction.
