Hi all, apologise in advance if the question is bit stupid, that's the first time I have a scooter in UK so I'm not sure about all the rules.
Just bought a new PX 125 and would like to change the catalysed exhaust for a 'normal' one, so in 3 years when is it time for the MOT do I have to put back the catalysed exhaust to pass it?
Thanks
