Awesome, looks mint
I had a Mugen Sport and a SuperSport 92 back in the day, my SuperSport was the next model after yours and had blue aluminum shock caps iirc and spoked wheels with special centre nuts which fitted flush to wheels they had 2 holes you used the Mugen supplied tool to undo with, I see yours has the black chassis, is it milled too? the 92's chassis was black also but milled out for weight saving, I seem to remember a front brake setup fitted also
