Why don't you email www.50cc.nl and see who is right!

OK, here's the manufacturer's link for the kit:

http://uk.catalogo.polini.it/en/pagina_710.116.html

Bore is 47mm, stroke is 37.4. BTW, I can't believe they shoehorned a 47mm piston/jug into the case, the jug skirt must be paper thin.

Now do the math:

Displacement = bore * stroke = (47/2)^2 * 3.14 * 37.4 = 64.8 cm^3

It's a 65cc kit, give or take.

This isn't exactly the first part vendor I've seen that doesn't know what he's dealing in. Always best to check with the manufacturer.
