Found this in polini catalogue, looks like the replacement for the original 47mm vision/rapido kit meant for afo5e motors, part no. 119.0034. This one is meant for the honda sh50 and has a different exhaust angle, but it might still be a usable option for early elite and aero owners.
Part no. 119.0035
