the person who commented below me clearly does not understand anything about how an expansion chamber works.
vespas are notoriously low rpm engines and the estoril has a relatively low powerband. match made in heaven

This pipe doesn't work with the port timing on Vespa mopeds. I haven't been able to figure out why my girlfriends Grande still barely goes 25mph with this pipe, a Malossi 65 kit, Polini variator, 13-13 dellorto and the thick Malossi belt. Then Chad Burke explained to me that the port timing will not work with the Tecno Estoril expansion chamber on a Vespa engine and that the Techno Circuit is the only one that actually works correctly. My good friend has the same setup on his Grande as my girls bike except he has the Techno Circuit and his ped goes 45-50 mph!? I will update this review when I put a techno circuit pipe on my girls ped.
