Difference between two articles that seem the same

Hello all,

Can someone please tell what is the difference between these 2 articles that seem the same ?

Art. n° PI623682 / https://www.sip-scootershop.com/main/base/Results.aspx?t=PI623682&_language=IT

Art. n° PI273337 / https://www.sip-scootershop.com/fr/products/top+case+piaggio+_pi273337

I have a 2017 Vespa Gts 300 Grigio Dolomiti and I need to get a topcase for it.

 

Thanks a lot.

Majid
