Tire Balance Bead Kit | Vintage Honda Motorcycles
A wheel that is out of balance shakes and takes the shine off an otherwise smooth ride. The old fix was clip-on lead spoke weights and a balancing machine or a truing stand full of assorted weights — assuming the job got done at all. Nuts to that. This kit balances your tires with glass beads that ride inside the tube and do the work for you.
Why You Need This
The beads roll to the light side of the wheel and clump opposite the heavy spot, balancing the whole spinning assembly in real time. Because they reposition themselves every time the wheel rolls, they keep the tire balanced for its entire life — and as the tire wears and its balance shifts, the beads simply follow. If you ever get a flat, you can recover the beads from the tube and reuse them.
How It Works
The beads are glass, and they go in through the valve stem after you remove the valve core. Inside the tire they distribute themselves against the heavy spots of the tire and wheel, evening out the whole rotating assembly. It is dynamic balancing that keeps working as you ride, with no weights hung on the rim.
What’s in the Kit
- 4 oz of balance beads (packaged in 1 oz bags)
- Two valve-core tool caps
- Bead installation bottle with applicator tube
- Tire pressure gauge (reads 10–50 psi)

Installation
Difficulty: Beginner
- Pull off the old weights first. Remove every clip-on spoke weight and stick-on rim weight before you start — beads and hung weights do not mix.
- Mount the tire, then add the beads last. Get the tube and tire mounted and the wheel back on the bike before you put any beads in.
- Check the valve stem. Some tubes have a restriction inside the stem that blocks the beads — probe it with the dull end of a drill bit. If it is obstructed, you will need a tube that lets the beads pass through.
- Pour them in slowly. With the valve stem up and the tire at the bottom, take the core out and tap the beads in through the applicator a little at a time — too fast and they clog. Rock the wheel back and forth on its axle to help them settle. Start with 1.5 oz per wheel for a standard street tire, and go up to 2 oz for a larger tire like a CL350 Scrambler or a CB550 rear.
Another way in: fill the applicator tube with beads and blow them through with compressed air.
After the beads are in, always point the valve stem up when you check pressure or add air, so the beads do not jam the valve core. They still can occasionally, which is what the core-tool caps are for — so check your pressure where you have an air supply on hand. Our install video walks through the whole process:
Frequently Asked Questions
Is one kit enough for my bike?
Yes. One kit balances both wheels of one motorcycle — the 4 oz of beads covers two tires at 1.5 to 2 oz each, and you get two valve-core caps to go with it.
The beads will not go into my tube. What is wrong?
Some tubes have a restriction inside the valve stem that blocks the beads. Probe the stem with the dull end of a drill bit; if it is obstructed, swap to a tube that lets the beads pass. These beads are not compatible with every tube brand, because valve-core designs vary.
How much do I use per tire?
Start at 1.5 oz for a standard street tire and step up to 2 oz for a bigger tire. If it still is not perfectly smooth, add the second half-ounce and re-check.
Do I still line up the tire’s balance dot?
Yes. Mounting the tire with its balance dot (the colored mark) at the valve stem gives the beads the best starting point.
