Mugen MBX-6 Mugen Seiki Racing is proud to introduce the New MBX6 1/8 Off-road Buggy. This buggy is all new from the chassis up! The MBX6 has all new design front and rear suspension components, front and rear bulkheads, all the drive train is light weight to reduce rotating mass, aluminum front pillar balls and the list goes on. The lay out for the engine, fuel tank and radio gear have been moved as close a possible to the center of the chassis to make the MBX6 as nimble as possible. Mugen Seiki Racing used its World Championship knowledge to continue to be the leader in the 1/8 off-road buggy market.
