can anyone help me out here? what is the difference between these two cranks?

and

2)http://www.sip-scootershop.com/EN/Products/45130000/Crankshaft+Vespa+GLGTSprint.aspx

 

 

I understand both are standard crankshafts (not race cut) for VBC. However the Meceur one (Art.Nr. 45153000) is rated at 1550g? and it says 54mm stroke? is that wrong?

I have 1975 vbc which and I am very sure it is a 57mm stroke crank. So can i use this meceur crank? is a lighter crankshaft better or worse?
