An update to the faulty Piaggio ignition switch

The Piaggio Keyless Rattle: Feature or Failure? An Update

Posted on: | Category:

For those of you who missed the drama back in August, here is the short version: My 2023 Piaggio Beverly 400 started cutting out mid-ride. The dashboard would die, the engine would kill, and I’d be left coasting in silence.

I traced the fault to the keyless ignition switch. The whole unit "floats" to allow you to push it in and open the glovebox, but mine had become so loose and rattly that road vibrations were breaking the electrical contact. My solution? I stripped the front of the bike and zip-tied the switch solid. It fixed the cutting out, but meant I couldn't lock the glovebox. (You can read the full breakdown of the issue and the "bodge" fix here).

Fast forward to now.

The Two-Month Wait

It took two months. Two. Months.

That is how long it took for Piaggio to ship a replacement ignition switch to Spain. If I hadn't come up with my zip-tie fix, the Beverly would have been sitting gathering dust for the entire late summer riding season.

But, finally, the call came. The part was in. I dropped the bike off, they fitted the new unit, and I picked it up.

The electrical cut-out issue? Gone. The bike starts and runs without dying. Success, right?

Well, sort of.

"It’s Normal, Señor"

As soon as I put my hand on the new switch, I felt it. The rattle.

It wasn't quite as bad as the old one, but it was still loose. It didn't feel solid. When I questioned the mechanic, he gave me the classic shrug and told me it was "normal."

I didn't buy it. I know what this bike felt like when it was new. It felt tight. Precise.

This is when the penny dropped. In my original post, and in my original thinking, I assumed the ignition switch and the floating assembly (the bit that moves to open the glovebox) were one single unit.

Clearly, they are not.

It seems the garage replaced the ignition switch (the electronic module that was cutting out), but they bolted it back into the original floating housing (the bit that rattles). They replaced the broken part, but they didn't replace the thing that broke it.

The Car Park Wiggle Test

To confirm my suspicions, I’ve essentially become a scooter stalker.

My first victim was a Beverly 400 I know parks regularly in a specific car park. I waited until the coast was clear and gave his ignition knob a wiggle. (Get your mind out of the gutter).

Result: Rattly. Not as bad as my one, but definitely loose.

A few days later, I needed some winter gear, because yes, contrary to popular belief, 8am in Malaga in January is bloody freezing, so I headed to Vespa Malaga. They are a massive dealer, which gave me the perfect sample group.

I found a brand new, zero-mileage Beverly 400 on the showroom floor. I tried the switch. Result: Solid as a rock. Zero play.

Then I found a used 2023 model, similar mileage to mine (around 9,000km). Result: Rattly. Exactly the same as mine.

The Conclusion

I’ve now physically tested four different Beverly 400s. The conclusion is pretty damning.

The plastic assembly that holds the ignition switch, the floating housing, wears out. Fast.

My bike has only done 9,000km. Yet the mechanism has developed enough play to feel cheap and nasty. In my specific case, I reckon the play became so excessive that the vibration physically shook the internal electrical contacts of the switch to death.

By replacing only the switch and not the worn housing, Piaggio has essentially put a fresh canary in the coal mine.

What makes it more frustrating is that I also tested a few older Piaggio MP3s. High mileage, battered old things. They visually use the same switch assembly, yet they were solid. No rattle. So Piaggio can make them properly, they just chose not to for the new Beverly.

So, What Now?

The conundrum is this: I have a new switch under warranty. It works electrically, but because it is sitting in the old, sloppy housing, it is already vibrating.

If the design is flawed, this new switch will eventually be shaken to pieces just like the last one, probably just after the warranty expires.

I am not waiting for that to happen.

I’m planning to strip the front end of the bike down again. I need to see what is going on in there. I suspect I will end up re-applying my "bodge."

I’d rather have a solid ignition switch and a glovebox I can’t lock, than a rattling switch that might leave me stranded at the side of the road again.

I’ll update you when I get the plastics off. Again.
