Description

Over long miles of riding through bad weather, the tiny electrical points inside your foot pedal sensor naturally wear thin or rust up completely. This slow maintenance reality leads to a twitchy, flickering, or completely dead rear warning lamp. Dealing with a broken sensor is a massive hazard that puts you in danger from cars riding your tail. Sourcing this high-quality aftermarket Hyosung rear brake switch is a vital fix for your bike. Because the factory altered wiring harnesses back and forth across different build years, checking your plastic plugs before buying is absolutely key. This specific unit drops straight onto frames using the standard white plastic socket layout, making your light system completely reliable on local roads.

📜 Confirmed Fitment Guide

Naked & Faired Sports Groups: Wire lead measurements are verified strictly for the sports chassis layouts noted below. See the diagram picture for location tabs.

  • Hyosung GT125 / GT125R Sport: Fits both carb models and injection variations.
  • Hyosung GT250 / GT250R Sport: Fits all unfaired and sports fairing variants.
  • Hyosung GT650 / GT650R Sport: Fits classic twin setups running standard foot peg plates.
❌ WILL NOT FIT CRUISER MOTORCYCLES:

  • GV Aquila Series: This wire lead is completely too short to stretch across cruiser frames. It will strictly not fit the GV125, GV250, or any bikes running non-matching round bullet pins.
💡 RECOMMENDED HARDWARE PAIRING: If your rear foot sensor is already rotting away from salt exposure, your front handlebar master cylinder switch is likely in a similar condition. Ensure complete electrical safety by matching this item along with a fresh Front Brake Light Switch. Browse Electrical Spares here.

🔧 Install Tips

  • Check Your Plug First: Before you open up the retail packaging bag, take a close look under your frame trim to double-check that your bike’s original plastic socket matches the white block plug shown in our product images. This saves any returns hassle!
  • Simple Prong Swap: Make certain your ignition switch key is clicked completely off. Unhook the old weathered line, slide the casing tab out of its frame notch, and push the new aftermarket pin connector firmly into place until it clicks.
  • Test Your Warning Lights: Always stand behind your bike and press the rear foot peg lever down hard to verify the stop lens lights up bright before you head out for a ride.
📧 NOT SURE HOW TO ATTACH your OLD PULL SPRING TO THE REARSET? If your brake light is staying stuck on or you aren’t sure how to snake the wire line behind your master cylinder reservoir, you can upload a crisp photo of your right-side footsets on the forum to get a quick walkthrough.
