Product Overview
This high-quality Original Front Brake Stop Switch is designed to meet or exceed factory performance standards and is suitable for Honda PCX125 (2021-2025) models.
The front brake stop switch is activated when the rider applies the front brake lever, sending a signal to illuminate the rear brake light and alert following traffic. When the switch becomes faulty or fails, the brake light may not illuminate when the front brake is applied, creating a serious road safety risk, or it may remain permanently illuminated, draining the battery and masking an original braking event. This original replacement restores correct brake light activation, ensuring your PCX125 signals reliably to other road users.

Complete Part Guide
The front brake stop switch is a vital safety trigger for the 2021-2025 Honda PCX125, governing both your rear stop light and the engine's ignition-start circuit. A failing switch means your brake light won't warn following traffic, and you may find yourself unable to start the engine. This original Honda part (35340-K1Y-DC1) provides the exact resistance and fitment required for the master cylinder. Held at Part Hive's London warehouse; we offer same-day UK dispatch for orders placed before the 1 PM deadline.
We often see Honda PCX-125s from 2021 onwards in the workshop with "no-start" issues or dead brake lights, usually caused by the tiny plunger inside this switch seizing up from road salt or grit. If you have to pump the front lever to get the dash to light up or to fire the starter motor, the internal spring is likely fatigued. This original Honda Front Brake Stop Switch (35340-K1Y-DC1) features a superior weather-boot compared to generic, low-grade alternatives. Replacing this ensures a crisp, rattle-free engagement and prevents the intermittent starting faults that plague high-mileage delivery scooters across North London.
