    Engine swap

    Just a quickie. Will a 2012 rs4 Derbi engine fit into a 2005 RS 50.

    The easiest way to do this would be to swap out the engine cradle, subframe, swing arm, and side stand support. This will have the effect of changing the engine mounts to the Derbi Euro3 engine. It is also posable to cut out the previous engine mounts and weld in new ones. That would be more challenging, in some ways.

    However, at this point it might be easier just to get an RS4.
