Scooterotica

We're all the exhaust IGM numbers on the GP/DL 125-200's all the same? I know they were physically the same, I think.

Out of interest it would be good to know if all original scooters with that exhaust had the same IGM number and it that number corresponds to any other IGM numbers on the scoots.

I know the questions are a bit anorak

Those are homologation marks. Usually they will relate to the part design like a registered design or kite mark. I think it unlikely that they'll be linked to the specific model.

No doubt an adult will along shortly to enlighten.

^ thanks. It not something that I've seen much information about and I've never tried to match the the IGM numbers you see on a scoot and see how they match or not as the case may be.
