Piaggio 290402 Complete Fuse Holder with 7.5 A Fuse – Vespa PX, Zip, Typhoon and Ape

The Piaggio 290402 complete fuse holder is the black box with a transparent lid that protects the electrical system downstream of the battery on a large number of Piaggio Group scooters from the 90s and 2000s — from the Vespa PX to the Zip, and from the Typhoon to the Ape Poker. It arrives already complete with a 7.5 A blade fuse. Official catalog name: "Complete fuse holder." Product code 290402.

✓ Key features

• Complete with fuse – the package already includes the 7.5 A brown blade fuse: there is no need to buy it separately.
• Transparent lid – you can see if the fuse has blown without dismantling anything, and it protects the contacts from water and dirt.
• Original spare part – this is the code specified by the manufacturer in the catalog, with the correct mounting and snap-fit for the original housing.
• One code for dozens of models – the same fuse holder is used for Vespa, Piaggio, Gilera, and Ape, from 50cc to 200cc.
• Part prone to aging – on these vehicles, the original fuse holder is often cracked, oxidized, or has loose tabs: this is a classic cause of intermittent electrical faults.

Technical specifications

Vehicle compatibility

List taken from the official Piaggio spare parts catalog (B2B). There are many applications: here they are grouped by brand and family. If your model does not appear, send us your VIN (chassis number) and we will check it.

Items to check along with this

• 290405 – the fuse holder bracket, the small mount that keeps it secured to the frame: it breaks often and is a separate part number.
• Battery cables and terminals – if the fuse holder was oxidized, the terminals leading to it are almost always oxidized as well.

Who is this for?

It is the perfect part for anyone bringing a twenty-year-old Piaggio or Gilera scooter or a Vespa PX back on the road and finding the fuse holder cracked, missing its lid, or with green oxidized contacts. It is inexpensive, takes five minutes to replace, and eliminates one of the most frequent causes of intermittent electrical failures — those where the scooter starts one day and not the next. It is also worth keeping as a spare in the under-seat storage.

Frequently asked questions

Is the fuse included?
Yes: the 290402 is the complete fuse holder and arrives with its 7.5 A blade fuse already inserted, the brown one you see in the second photo. You don't need to buy anything separately, except for the 290405 bracket in case yours is broken.

Is it suitable for my Vespa PX?
Yes: the Piaggio catalog lists it for the Vespa PX 125 E, PX 150 E, and PX 200 E from historical catalogs, for the PX 125 30th Anniversary from 2007-2008, and for the PX 125 and 150 2T E3 from 2011 to 2017. It is the same part fitted to ET2, ET4, Zip, Typhoon, and Ape Poker.

Can I use a 10 A or 15 A fuse?
No. The amperage rating for this system is 7.5 A and must be respected: a larger fuse does not "solve" anything, it simply stops protecting the system and lets the cables or components burn, leading to much more expensive damage.

How do I know if the fuse holder needs changing?
Signs include a cracked or missing lid, contacts that are blackened or green with oxidation, tabs that no longer hold the fuse, and especially electrical faults that come and go when the cables are moved. If the fuse wobbles in its housing, this is the part you need.
