i thought it had to be a spacer/reducer for the air inlet on the carb? , from what i've been told by my neighbour who had one these put in its not only the part that costs but the garage that charge you for the install, her's was £300! but then like i said it was different to this so i wouldnt like to say.
i know alot of insurance companys do not like bigger bikes that have been restricted as they say its too tempting.
so i would also check that out before getting it put on too.
