The capacitor is one of those components that eventually causes problems on every Motom. Original vintage parts don’t last long, and stock parts are even less reliable—the insulating material ages over time, and performance gradually declines.
The Motom electronic capacitor is the most reliable replacement for the original vintage capacitor.
The good news is that there is an affordable, reliable solution that’s accessible to everyone: the modern electronic capacitor, the same type used on circuit boards. You can find them online for just a few cents.

Which capacitor should I buy?
Here are the features to look for:
- Capacitance: 0.3 µF (microfarads) or 330 nF (nanofarads) — they are the same
- Voltage: minimum 400 V, preferably 600 V
- Voltage type: AC (alternating current) is preferred, but DC (direct current) is also acceptable
- Type: electrolytic or film — both work
An important note: these capacitors are non-polarized, so you don't have to worry about which way to install them.
Electrolytic or film?
Film capacitors are encased in plastic and offer better insulation. Electrolytic capacitors are more compact. In practical terms, both work perfectly—just choose whichever one is easier to find.

How to assemble it
The easiest way is to mount it externally, even when the coil is internal. It’s convenient, quick, and works perfectly.
Field-tested
It’s not just theory. I installed this system on my Motom and rode over 4,000 km with it at TerreMotom without a single problem.

How long does it last?
Their lifespan can't compare to that of vintage capacitors. On a Motom, a modern electronic capacitor practically lasts forever.
Just a few cents, no hassle, no compromises. If your Motom still has the original capacitor, it’s time to replace it.
