Wheels & Tyres
What are Wheel Bearings?
The sealed bearings inside each wheel hub that let the wheel spin freely for thousands of miles.
Simplified animation — not to scale.
In plain English
Packed with grease and sealed against water and dirt, wheel bearings let the wheel rotate smoothly around the axle with minimal friction, ride after ride.
A simple analogy
“The tiny ball bearings inside a skateboard wheel, scaled up to handle a motorcycle's weight and speed.”
How it works
Rows of small steel balls or rollers sit between an inner and outer race, allowing the wheel to spin with very little resistance while still supporting the bike's weight. Seals keep water and road grit out; once they fail, contamination quickly wears the bearing out.
Signs of trouble
- ⚠Grinding or growling noise that changes with wheel speed
- ⚠Play or wobble when the wheel is rocked side to side
- ⚠Vibration through the bars or footpegs
- ⚠Uneven tyre wear from a loose or notchy bearing
