The SpinFaktor was YoYoJam's original composite-material yo-yo, based on the body design of the DragonJam. Commonly referred to as the original SpinFaktor, this yo-yo was YoYoJam's very first high-performance model. YoYoJam also had a special release of the SpinFactor, the Linda Sengpiel special edition. As with the original model, two versions were realeased, the first with engraved rims (no side caps) and the second with side caps. Apart from the golden-colored weight rings, white body color and decals, the yo-yos were identical to the normal versions.
