Encaja fatal en Pro 2, el material es malísimo. No recomiendo la compra. It fits badly in Pro 2, the stuff is lousy. I do not recommend the purchase.
1) Hook base has ring shaped ledge at the side that connects to scooter. The ring diameter is much larger then the hole around the screw slot at scooter, so the hook base will stand out too much and it would dangle when scooter is shaking. So I had to saw the ring off and polish the surface. 2) The insides of the hook has rough edges from coarse metal stamping, they are sharp and can damage handles of the bag you want to hang at this hook. So I had to shave them off with a file. Then I have painted the whole thing with black paint by spray and after that it can be used just fine. All this should have been done by manufacturer, so the quality is low.
