G5 Concept

A YoYoFactory Initiative

Forget the rules.. defy convention....explore new horizons

Changing the shape of the future is the all new G5 by YoYoFactory.


With the 401k you play your way. With the G5 Concept you get to redefine PLAY



1st the shape….

Inspired by a clean slate and an ambition to push play frontiers, the G5 Concept is the first shape of its kind designed for the purposes of advanced play. And when we say advanced, we mean play that doesn’t even exist yet. Don’t even try comparing this with other new shape butterfly yo-yos you have seen in recent weeks.


The extreme volumetric profile provides a wide area for more comfortable catch, decreased center mass allowing increased maneuverability. Obviously the rim weighting is outstanding with the added bonus of grind control. Fingers can slot in the Id for finger grinds while palms contact the Od while the Od glides above with zero friction. The basic profile also welcomes thumb grinding. There is also the potential for new Y-axis grinds never seen before!




The Hub stacks

The G5 features 2 additional beaings securely mounted along the same axis of the main bearing either side of the it. A fixture securely is attached to it the bearing allowing it to be held or balanced on while the yo-yo is spinning allowing you to change the plane/axis of spin. It also allows the yo-yo to be spun with a ripping action rather than a throw. Previous efforts (both commercially producing and home modification) at side mounted bearings in yo-yos have had very little success. The G5 breaks through, bringing new possibilities to more people with a new method of attachment giving unmatched performance. The bar has been lifted.


The best thing about the G5 concept? It is reality....


Think of the G5 Concept as more than just 'a yo-yo'. You are witnessing multiple steps of evolution happening before your eyes. YoYoFactory is attempting a fluid process and one I hope people will enjoy being a part of with an open mind. Nothing is certain with this project...
