Dual-Spin (二回転, Ni Kaiten; Two Rotations) Beyblades, as the name implies, are Beyblades that have both Right-Spin and Left-Spin capabilities. As such they are able to spin in a both clockwise and counterclockwise directions. Dual-Spin is also sometimes referred to as Dual Rotation or LR (Left-Right) due to having both spin directions available.
In the Original Series and Metal Saga, Dual-Spin Beyblades such as Torch Pegasus and Gravity Destroyer AD145WD had this feature inherently built into their designs. While this remained true initially in the Burst Series for Beyblades such as Legend Spriggan 7 Merge, following the introduction of the Gatinko Layer System in Beyblade Burst Rise, Dual-Spin Beyblades such as Master Diabolos Generate and World Spriggan Unite' 2B require mode changes in between battles to change spin directions. With the release of the Gatinko Layer System in Beyblade Burst Rise, some components are only compatible with those of the same spin direction. Dual-Spin parts are often compatible with both Right-Spin and Left-Spin parts.
