Who it's perfect for

It's the replacement for those whose speedometer needle is stuck at zero, or jumps and makes noise while riding. On the Carnaby 300 Cruiser, this is a typical age-related fault: the inner wire frays precisely where the sheath makes the tightest bend, under the front wheel, where it is exposed to water, salt, and mud. It's inexpensive, can be changed in half an hour without special tools, and is also necessary for passing inspection: with a speedometer that is stopped or irregular, the outcome will be negative.

Frequently asked questions

Which scooter does the Piaggio 650950 cable fit?
The code 650950 is specified in the official spare parts catalog for the Piaggio Carnaby 300 4T ie Cruiser produced from 2009 to 2012, frame prefix ZAPM60400. It is a specific code for this version: other Carnaby engine sizes use a cable of a different length.

What exactly is this part?
It is the speedometer cable: the flexible cable that transmits motion from the front wheel to the dashboard instrument. It is a mechanical cable transmission, not an electronic sensor, which is why the length, sheath, and terminals must be original.

Where exactly is it located on the vehicle?
It runs from the drive unit screwed onto the front wheel hub to the back of the instrument cluster. In the official Piaggio spare parts catalog, it is position 1 of table 05.03 "Cables", in the Braking system group. Only one piece is specified per vehicle.

Why does the speedometer move erratically or remain stationary?
In the vast majority of cases, it's the inner wire of the cable that frays: it loses grip and the needle jumps or stays at zero. Less often, the cause is the drive unit on the wheel hub or a seized instrument. The cable is the cheapest of the three to try.

Is the drive unit on the wheel included?
No. Only the complete cable is supplied: sheath, inner wire, and the two terminals. The speedometer drive unit on the front wheel hub is a separate spare part: if it is worn, it is advisable to replace it together, otherwise, it will also damage the new cable.

Can I install it myself and what tools are needed?
Yes. The terminals have a knurled ring that can be unscrewed and screwed by hand: remove the old cable from the drive unit and from behind the instrument, and reassemble the new one following the same path, without tight bends. It takes a few minutes and no special tools.
