This model was designed to replace and update the original SpinFaktor from YoYoJam. Often called simply the SF2, the redesign was a more streamlined design than the original, without the rubber weight rings on the outside rim. No response system, but as with other models, the recessed holes around the axle worked as a very weak starburst.

Pictured here is a later SF2 from the summer of 2004, in all black. Most of these had red caps.
