🛠️ Installation & Safety Tips:

⚠️ ALWAYS replace the front sprocket locking washer
(click here if you need to buy the washer too!) when fitting this nut. Reusing an old or bent washer is dangerous — it will not hold the nut in place properly.

If this nut loosens during riding, the front sprocket can fly off, causing:

• ⚙️ Damaged output shaft threads

• 🛞 Chain whipping and locking onto the swingarm

• 💥 Possible holes in your crankcase

• 🤕 And in the worst cases, loss of control or serious injury

🔧 Torque the nut to spec, bend the new washer over the flat of the nut, and apply thread locker for added security.
