📦 Front Sprocket Nut + Lock Tab Washer Set for Hyosung GT650 / GT650R / GV650

This listing includes two critical parts for your drivetrain service or sprocket change:

• 1x Sprocket Retaining Nut — Part Number: 09159H20001 

• 1x Lock Tab Washer — Part Number: 09167H25004 

These are genuine-spec replacements for the original Hyosung components used on all GT650 / GT650R / GV650 motorcycles from 2005 to 2020. Over time, the washer’s tab can weaken or break from repeated bending, and the nut itself can loosen from vibration. Replacing both is strongly recommended when installing a new front sprocket to prevent serious damage to your gearbox output shaft or sprocket coming loose while riding.

🔧 These parts are small but essential, especially during chain and sprocket changes. Avoid reusing worn or deformed locking washers — it’s not worth the risk.
