Description

The clutch inner hub manages the mechanical power transfer directly from your 125cc V-Twin or single-cylinder engine down to the gearbox assembly. Over extended mileage on the road, the cast aluminum columns of this center basket can develop heavy notches, ruts, or grooves from continuous plate friction. These physical ridges cause the steel and friction plates to hang up or stick, resulting in a rough, clunky gear change or severe difficulty finding neutral at a standstill. This replacement hub is manufactured to standard factory specifications, providing a clean, flat surface to restore smooth gear selection and standard clutch lever operation.

OEM Spec Fitment

Crucial Repair Part
Direct mechanical fix for sticky shifting, severe clutch drag at lights, and heavy gear transmission click noises.

📜 Confirmed Fitment Guide

✅ FITS: GT125 naked, GT125R (Sport), GT125P, GV125 Aquila, RX125 SM / Offroad, and RT125 Karion / D models.
📅 YEARS: All traditional carburetted 125cc motor variations (typically running from 2001 up to 2017).

❌ WILL NOT FIT: Any 250cc or 650cc engines (such as the GT250R, GV250, or GT650). Larger engines use a completely different internal hub diameter, spring post footprint, and input shaft spline count.

💡 RECOMMENDED PAIRING:
Always replace your worn friction plates and return springs when installing a replacement center hub to guarantee balanced assembly wear and eliminate clutch slippage under load. View 125cc Clutch Kits here.

🔧 Install Tips

  • New Gasket Required: Always fit a fresh right-side clutch cover gasket and drop in completely fresh engine oil whenever opening up the main engine side casings.
  • Torque Specs: Ensure you use a proper, calibrated torque wrench to tighten the central hub locking nut down to manufacturer specifications. Avoid using aggressive air impact wrenches which can warp the basket teeth or damage input shaft threads.
