The Activa front wheel bearing number is 6201, a sealed deep groove type whose bore is 12 mm, 32 mm outside diameter and 10 mm width, and the front wheel uses two of them. Parts listings for the Activa front wheel, including the 6G with its 12 inch front rim, give this same number.
Bearings rarely fail on a new scooter, but an Activa that has done years of daily commuting through waterlogged streets, rough patches and speed breakers often needs a pair. A worn bearing makes the front feel loose and can ruin the brake drum and hub if ignored.

The number decodes simply. The 6 means a single row deep groove ball bearing. The 2 is the light series. The 01 stands for the 12 mm bore. Letters after the number describe the seals and clearance, for example 2RS for rubber seals on both sides, and a C3 mark for slightly more internal play.
Seal letters you will see after 6201
Listings for the same Activa wheel show suffixes such as 2RS, 2RS C3 or UL. The size is the same; the seal and clearance differ. For a scooter that crosses flooded roads every monsoon, ask for a bearing sealed on both sides with rubber seals, since metal shields keep out grit but not water. If you can, match the marking on the old bearing. If the old one is too worn or rusty to read, the 6201 2RS type is the common choice.
Does it differ between 3G, 4G, 5G and 6G
The listings we checked give 6201 for the Activa front wheel generally and for the 6G by name. We could not find a separate catalogue entry for every older generation, so if you own a 3G, 4G or 5G, measure the old bearing or read its number before buying. The three measurements, 12, 32 and 10 mm, settle it. A 6301 is a different, thicker bearing and will not fit a hub made for 6201.
Signs the Activa front bearing is worn
- A grinding or humming sound from the front that rises with speed.
- Free movement when the raised front wheel is gripped at twelve and six o'clock and pushed back and forth.
- The wheel feels rough or notchy when spun by hand.
- Uneven wear on the front brake shoes, or a brake drum that heats up on one side.
- Vague steering on straight roads that is not explained by tyre pressure.
Replacing the Activa front wheel bearings
- Put the scooter on the centre stand and lift the front with a block under the floor.
- Disconnect the speedometer drive or sensor and the brake cable or caliper as fitted.
- Remove the axle nut and slide out the axle, then the wheel.
- Tap each worn bearing free from the hub using a brass punch, moving it round the inner race in small steps.
- Clean the hub and check the spacer tube between the bearings.
- Seat the new pair by pushing only on the outer race, using a socket that matches its 32 mm edge.
- Reinstall the wheel, torque the axle nut, and squeeze the front brake a few times before you set off.
Always replace both bearings together. If the hub seat is worn and the new bearing slides in loosely, the hub or wheel needs attention; do not glue a bearing in place.
Buying 6201 bearings for an Activa
Request a pair of 6201 bearings with rubber seals on both sides for an Activa front wheel. Mention your generation. A sealed bearing from a reputable bearing maker lasts far longer than an unbranded one, which is what usually makes one cost more than another. Check the box shows the full number and that the bearing turns smoothly with no gritty feel. Fitting takes a mechanic a short time, and many fit them while you wait.
Questions owners ask
What is the Activa front wheel bearing number?
6201. It measures 12 mm bore, 32 mm outside and 10 mm wide, and the front wheel uses two.
Does the Activa 6G use the same front bearing?
Yes. Listings for the 6G front wheel give the 6201 bearing, despite the bigger 12 inch front wheel on that model.
Can I use a 6301 bearing instead?
No. A 6301 is larger and thicker and will not fit a hub built for 6201.
What does 2RS mean on a 6201 bearing?
It means rubber seals on both sides, which keep out water and dust. It suits Indian monsoon riding well.
What are the clues that my Activa front bearing has worn out?
A droning or grinding note from the nose, free play when you rock the raised wheel, or a gritty spin by hand all point to tired bearings.
Should I replace one bearing or both?
Both. They have done the same distance, and replacing one usually means the other fails soon after.
