Piaggio 584599 Engine Kill Switch – Beverly and BV 125, 250, 300, 400 and 500 (2005-2011)

The Piaggio 584599 engine stop button — the red emergency button on the right handlebar control, also called the run/stop switch or kill switch — is the original spare part for Piaggio Beverly and BV maxi-scooters in 125, 250, 300, 400, and 500 displacements, from 2005 to 2011. It's the control that cuts off the ignition circuit and instantly switches off the engine: when the contacts oxidize or the button gets stuck, the scooter won't start or stalls while riding, and these are faults that seem much more serious than they are. New spare part, original Piaggio code, ready for delivery from Moon Bike S.r.l. — Cercola (NA).

• One code for the entire range – Beverly and BV from 125 to 500, across seven years of production

• New product, never mounted · shipped from Italy

Recommended products

• Complete right-hand control block – if, in addition to the engine stop, the starter or lights are also damaged
• Contact grease for electrical connectors – always apply when reassembling: doubles the button's lifespan
• Side stand switch – the other component that causes the exact same symptoms
• Luggage rack cover 623358000C and dashboard transparent cover 640513 – other Beverly spare parts we have in stock

Who is it perfect for?

It's the spare part for those with a Beverly that occasionally won't start: you turn the key, press the starter, and nothing happens, then you move the red button back and forth and it restarts. This is the classic symptom of oxidized contacts in the stop button, and after a few years of rain on the handlebars, it happens to almost everyone. It's also for those whose scooter stalls while riding over bumps — same cause, but much more annoying. It costs a few euros and in half an hour it removes a fault that, from the seat, looks like an ECU or a fuel pump problem.

Frequently asked questions

What exactly is this part?
It is the red engine stop button on the right handlebar control, the one with run and stop positions. It cuts off the ignition circuit and switches off the engine. It has 3 contacts and is the original Piaggio spare part, not a universal button.

My Beverly sometimes won't start: could this be why?
Yes, it's one of the most common causes. If moving the button back and forth makes the scooter restart, the contacts are oxidized. Before ordering, however, check the continuity in both positions with a tester: the same symptoms can also come from the side stand switch or a fuse.

Will it fit my Beverly?
It fits Beverly 125, 250, 300, 400, and 500 and American BV models, RST, Sport, and Tourer versions, from 2005 to 2011. If your model is not listed, send us the VIN and we will check the official catalog.

Does it include the control block?
No. Only the engine stop button is supplied. The complete control block, wiring, and screws are separate spare parts: if the starter button or light button is also damaged, ask us for the entire block.

Can I install it myself?
It's an operation within reach for those with some DIY skills: you disconnect the battery, open the right control, slide out the old button, and insert the new one. Apply a thin layer of contact grease to the terminals before closing: that's what prevents you from being back to square one in two winters.

Is it original or a reproduction?
It is the original Piaggio code 584599, new and never mounted. Universal buttons cost less but must be wired manually and do not have the original connector: it's not worth it for a safety component.

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