Original Piaggio spare part for Vespa GTS 125, 150, 250, and 300. Product code 650849.

✓ Strengths

• Original Piaggio spare part – the same code indicated in the official spare parts catalog under the "Braking system - Transmissions" group, in the "Transmissions" table.
• Complete with casing and wire – it's not just the inner wire: it arrives ready to be installed, with the terminals already in place.
• Standard size 1154 / 1134 mm – the length specified by the manufacturer, which allows for the correct curve behind the leg shield.
• A single code for four engine sizes – Vespa GTS 125, 150, 250, and 300, from 2005 to 2017.
• It's the part you look for when the needle fluctuates or stays at zero – the most common malfunction of mechanical speedometers is not the instrument itself, but the cable.

Technical features

Vehicle compatibility

The list is taken from the official Piaggio spare parts catalog (B2B area). If you have any doubts, send us your scooter's chassis number and we will verify the correct code.

Perfect for

This is the part for anyone with a Vespa GTS whose speedometer needle fluctuates, squeals below fifty, or simply stopped working overnight: nine out of ten times, it's not the instrument that's broken, but the wire inside the casing that has frayed. It's also a part that workshops keep in stock, because a single code covers GTS 125, 150, 250, and 300 from 2005 to 2017, and on a vehicle used daily, the speedometer cable is a consumable. And, in a country where the speedometer must function for inspection, it's a repair that cannot be postponed.

Frequently asked questions

Which Vespa models use the 650849 cable?
In the official spare parts catalog, this code is assigned to Vespa GTS 125 Super, GTS 150 Super, GTS 250, and GTS 300, including Super, Super Sport, and Touring versions, from 2005 to 2017 in EMEA, APAC, and NAFTA markets. Exact versions and years are in the table above: we do not declare compatibility outside of those listings.

Where exactly is it located on the vehicle?
It runs from the speedometer drive on the front wheel hub to the back of the instrument cluster, passing behind the leg shield along the steering head. In the official catalog, it is located in the Braking system - Transmissions group, on the Transmissions table, where it is the only item specified for GTS models, in a quantity of 1.

How long is it?
The casing measures 1154 mm and the inner wire 1134 mm. This is the standard size for GTS models: before ordering, it's advisable to lay out the old cable and compare. If yours is significantly shorter, your vehicle uses a different code, and you should send us your chassis number.

What other codes does the catalog indicate?
On the same line of the table, the catalog pairs it with 56306R, and spare parts catalogs also list 601321 as a reference for the same part. If you have an old delivery note or order with one of those two numbers, this is the spare part you need today.

How do I know if the cable is broken?
Unscrew the ring nut on the wheel side and pull out the inner wire: if it is broken, frayed, or spins freely, that's the culprit. If the wire is intact and the needle moves when you rotate it by hand, the problem lies upstream, in the drive on the hub or the instrument itself.

Do I also need to change the speedometer drive?
Always check it. The drive has a square seat that pulls the wire: if the cable broke inside there, that seat is often rounded. Installing a new cable on a worn drive means redoing the work after just a few hundred kilometers. The drive is a separate code.
