The SpinFactor HG Xtra by YoYoJam was released in Fall 2005 as a limited production test run, with only 80 yo-yos produced. It is a variant of the SpinFaktor HG, featuring heavier Heavy Gravity rims than with the original. As a result, it is a particularly heavy yo-yo for its size at a whopping 80 grams in weight.
