A Japan Cup 2026 commemorative edition of the Torque-Tuned 2 PRO, the double-shaft motor for Mini 4WD PRO chassis. It keeps the torque bias that makes the Torque-Tuned 2 a technical-course motor while adding gold-plated brush terminals to the JAPAN CUP 2026 specification, behind an orange end bell and a gold event label.
Released 20 June 2026 alongside the single-shaft Torque-Tuned 2 Motor J-CUP 2026 and the Hyper-Dash 3 Motor J-CUP 2026. Being double-shaft it fits the MS and MA chassis and will not fit a standard single-shaft chassis, so check which machine it is going into before ordering.
