Voltage Regulator Rectifier For Yamaha TW200, XT225, XV250 & TTR250

Product Overview

Restore the electrical heartbeat of your Yamaha with the GOOFIT Precision 4-Pin Voltage Regulator Rectifier. If your bike is suffering from dimming headlights, a frequently dead battery, or erratic engine performance, your factory regulator is likely failing.

Engineered specifically for Yamaha's legendary lineup—from the rugged TW200 trail bike to the classic XV250 Virago—this unit converts AC power from the stator into stable 12V DC power. Built with an advanced heat-sink design and "Plug-and-Play" connectivity, it protects your battery from overcharging while ensuring all electronics receive a consistent, flicker-free current.

Mechanic’s Diagnostic Tip

Is your regulator bad? Use a multimeter to check the battery voltage while the engine is running. If the voltage stays below 13V or spikes above 15V when you rev the engine, your regulator is likely faulty and needs immediate replacement to prevent battery damage.
