The new Mugen Seiki MBX8R baby carriage has been tested and developed by some of the world's top drivers. Throughout 2021, the Mugen Seiki team spent a lot of time testing and developing the MBX8R's geometry in race conditions, resulting in many victories. Ryan Maifield won The Dirt Nitro Challenge, Silver State Nitro Challenge, and ROAR 1/8 Off-Road National Championship in the same year. The MBX8R includes many new parts for improved stability, rear traction, jumps, and a wider tuning range.
