Voltage Regulator Rectifier for SYM GTS300i, RV250, Joymax 125/300 & Z300i | 31600-L4A-000

GOOFIT Maxi-Scooter Series – High-Precision 12V Voltage Regulator

Keep your commute smooth and your electronics safe. The GOOFIT Voltage Regulator Rectifier is a premium replacement part engineered for modern high-displacement scooters, including the SYM GTS, Joymax, and RV series. In fuel-injected (i) and ABS-equipped scooters, consistent voltage isn't just a luxury—it's a requirement. This regulator stabilizes the power from your stator to ensure your battery stays charged and your digital dashboard remains protected from surges.

Crafted from high-quality, heat-conductive materials, this unit features a ruggedized shell designed to withstand the high-vibration and enclosed-engine heat typical of maxi-scooters. Its lightweight design and high-reliability circuitry provide a long-lasting, low-maintenance solution for riders who depend on their scooters every day.
