How to Determine if the Rear Wheel Bearing of a Motorcycle is Damaged?

You will feel bumps at the same frequency, meaning there is a sensation of going over a bump every time the wheel completes one or several rotations. There will be a clicking sound when you sit on it. It may directly seize up. The rear wheel won't turn and can only be dragged.

Having ridden motorcycles for over a decade, identifying a faulty rear wheel bearing is quite straightforward. If you hear continuous squeaking or humming noises while riding, which get louder with speed—especially when turning—that's the first sign. After parking, I immediately prop up the bike and shake the wheel side to side by hand. If there's noticeable looseness or play, it’s likely a bearing issue. If the wheel hub center feels unusually hot to the touch, that’s another sign of bearing wear. Neglecting repairs can worsen the wear, leading to wheel lock-up or unstable riding, posing safety risks. It’s best to perform regular checks, like quickly shaking the wheel monthly, to prevent surprises. On my last long trip, ignoring minor noises forced an emergency repair midway, wasting both time and money.
