Piaggio 164604 Handlebar Clamp - Ciao

The Piaggio 164604 handlebar clamp is the original spare part that secures the handlebar of the Piaggio Ciao. In the Piaggio catalog, the official name is simply “clamp”, and the code replaces the previous 137297. It’s a classic, inexpensive part that can halt a restoration: when the clamp is rusty, deformed, or stripped, the handlebar won’t stay in place, and there’s no way to fix it without the right part. 🔴 Code out of production by the manufacturer: what’s available is old stock. New, never-mounted spare part, available from Moon Bike S.r.l. — Cercola (NA).

✓ Strengths

• Original Piaggio code 164604 – not an imitation nor a universal hardware clamp
• Replaces code 137297 – if you find the old reference in your exploded diagram, this is the updated replacement part
• Out of production – Piaggio no longer supplies it: what’s available is residual stock
• The part that unblocks the restoration – costs very little but without it, the handlebar cannot be properly mounted
• New product, never mounted · shipping from Italy

Who is it perfect for?

It's the spare part for those who are restoring a Piaggio Ciao and got stuck on a three-euro detail. It always happens like this: the engine is fine, the paint job is done, and then the handlebar clamp is missing — rusty, deformed, or lost by someone who disassembled the vehicle twenty years ago. It's also the part sought after by spare parts dealers and clubs, because Piaggio no longer produces it: what circulates is residual stock, and when that runs out, only used parts or adaptations remain, which don't look as good on a well-restored vehicle.

Frequently asked questions

What exactly is this part?
It is the handlebar clamp for the Piaggio Ciao. In the Piaggio catalog, the official name is simply "clamp", because the same code is used on multiple vehicles.

I found code 137297 in my exploded diagram: is it the same?
Yes. The 164604 officially replaces the 137297: if your catalog or the old part shows the old number, this is the updated replacement part to order.

Will it fit my vehicle?
Our definite indication is the Piaggio Ciao. However, the catalog assigns this code to 60 different vehicles: if you have another vintage Piaggio model, send us the frame number and we will verify it before shipping.

Is it still produced?
No. The code is out of production by the manufacturer: what is found on the market is residual stock. This is why, for an inexpensive part, it's best to get it when it's available.

How many do I need?
The package contains one clamp. If your vehicle uses more than one, order the corresponding number of pieces.

How long does it take to arrive?
The item is available in stock and shipped from Italy. You will receive the tracking code as soon as the package leaves.
