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.

Fitment FAQ
Will this part fit my specific model and year?
This voltage regulator rectifier is intended for This precision unit is a direct replacement for the following models (2012–2016); SYM GTS Series: GTS 125i, GTS 300i, GTS 300 ABS.; SYM Joymax/Citycom: Joymax 300, Z300i, HD300i.; SYM RV Series: RV250, 300 Max.; OEM Part Number: 31600-L4A-000.. It is best matched to original part number(s) 31600-L4A-000. Key physical/spec details from the product data include GOOFIT Maxi-Scooter Series – High-Precision 12V Voltage Regulator, 12V, 125cc. Use the compatibility table and product photos together before ordering.
Do I need to match the OEM part number?
Yes. Match your original part number to 31600-L4A-000 before purchase. For this voltage regulator rectifier, also compare the OEM number, plug shape, pin count, mounting-hole distance, heat-sink style, and AC/DC charging-system type. This is especially important for SYM RV250 models because similar model names can use different parts by year or trim.
What models or situations does this part not fit?
Do not order this voltage regulator rectifier for machines outside the listed compatibility, or for units with different pin counts, plug shapes, AC/DC system types, or mounting-hole spacing. If your original part number does not cross-reference with 31600-L4A-000, treat the fitment as unconfirmed. Model years outside 2012–2016, 2012, 2016 should be verified separately. Do not rely only on the model name or engine size.
What should I check before ordering?
Before ordering, compare your original part with the photos and check the OEM number, plug shape, pin count, mounting-hole distance, heat-sink style, and AC/DC charging-system type. Confirm OEM/cross-reference number(s): 31600-L4A-000. Recheck listed specs such as GOOFIT Maxi-Scooter Series – High-Precision 12V Voltage Regulator, 12V, 125cc. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
