🛑 FRONT BRAKE LEVER // RESTORE STOPPING CONTROL

Banish spongy finger reach and twisted control hardware. A bent or snapped front brake lever compromises your primary safety setup and will fail an MOT test. This high-quality aftermarket component acts as your essential control insurance, dropping straight onto your factory master cylinder pivot so you don’t get left stuck in the garage waiting weeks for overseas parts or fighting with cheap bodge alternatives that don’t actuate the piston correctly.

  • OEM-Style Fitment // Designed specifically for original TCTC master cylinders.
  • Durable Finish // Classic black finish matches original factory specifications.
  • Safety Essential // Restores a responsive, crisp pressure bite to the front caliper.
  • 📦 Color & Contents // Includes 1x replacement hand lever. Dispatched in black by default (⚠️ silver colour might be sent only if black stock is temporarily exhausted).
CRITICAL FITMENT WARNING: This is a slimmer, 125cc-specific lever design.

It will not fit larger 250cc or 650cc models, which use a significantly thicker master cylinder casing and fluid piston yoke.

📜 Confirmed Fitment Guide

✅ FITS: GT125R, GT125, GT125RC naked, RX125, RT125 Karion, and GT125P configurations.
📅 YEARS: Standard carburetted model runs spanning from 2003 through to 2020.

❌ WILL NOT FIT: Any 250cc or 650cc models (such as the GT250R or GT650R). Larger capacity twins carry thicker master cylinder piston castings which require a completely different lever pivot width.

💡 ESSENTIAL PAIRING:
If your brake light fails to illuminate immediately when squeezing the front control, your master cylinder switch is likely worn out. Stop dangerous tracking faults by matching your new blade with a fresh **Front Brake Light Switch**. Shop our brake light switches.

🔧 Pro Tips

  • Double-Check Fitment: Make absolutely sure your handlebar carries the original factory Hyosung TCTC branded master cylinder assembly. This lever blade will not mount correctly into unbranded, generic Chinese aftermarket clone master reservoirs.
  • Safety First: Ensure that your brake light switch plunger clicks and activates the rear lamp perfectly post-assembly, and verify that the lever blade carries proper free-play slack before setting off.
