    Aprilia Mojito custom spark plug and variator belt


    kindly ask for help.

    I drive Mojito custom with Piaggio (ZD4TFA) motor year 2013 and would like to change spark plug and variator belt.
    Which spark plug is correct. I bought it from second hand and have no manuals.
    On web i found: NGK BR8ES, NGK BR9ES, Champion RN1C with alternative NGK BR10ES.
    Which one shall i buy?

    Second question refer to variator belt. Again found many sizes and no idea which dimension is right for my Mojito?

    Thanks in advance

    on the sticker under the seat it is writen. also on the sparkplug it is writen.

    nr2c or possibly rn2c are the correct ones. the ngk plugs dont work long in the piaggios so stick to the champions.

    the OEM spark plug is a champion RN2C equivalent to NGK BR9ES
    the NGK works better on this machine

    the best driving belt is the original Piaggio belt made by Mitsuboshi (size 811x18.5)
