Mugen have introduced a new one-piece aluminium motor mount for the MBX8. It is machined from high-quality aluminium and it comes with a grey surface finish for wear and looks. Using the one-piece mount over the original multi-piece part will improve crankcase support for improved engine and ball bearings durability while also increasing chassis strength and reducing torsional flex. The mount is a direct fit and it will hit stores from end of May.
