- Doesn't seem to last very long

Special points of interest:
One of a kind. Doesn't work with every engine the way it should.

Consists of:
Rotor
Stator
Coil
CDI
Light coil (optional)
+ Works up to 18.000 RPM
+ Is moisture resistant
+ CDI ignition
+ Easy to install
+ Light flywheel (Better throttle response)
+ Curve
- Expensive
- No lights (There is a light coil available, but it delivers just 12v 10W. Barely enough to run lights)
- Hard to tune precise
- Parts that can break are expensive
Special points of interest:
Only ignition with curve for Puch.
- Curve means that it has a programmed CDI that delays the ignition when the RPM rises. This ensures that you have good low-end and high-end power.
Selletra analog CDI inner-rotor
Consists of:
Stator
Rotor
Coil
CDI
Baseplate
+ Works up to 18.000 RPM
+ Is moisture resistant (Plastic plated stator, coil & CDI)
+ Light flywheel (Better throttle response)
+ CDI
+ Quality, finish and fit
- Not meant for Puch (It's meant for Piaggio & Minarelli. It does fit Puch)
- Expensive
- No light coil
- No curve* (Analog, does not delay the ignition timing)
- Hard to tune
Special points of interest:
Not meant for Puch, but for scooters.
Brand:
Italkit Selletra
Malossi Selletra
TNT Selletra
They are basicly all the same.
- Only Malossi has an Eprom. That's a self-programmable CDI so you can make your own curve. It is expenive however.
There's also a digital Italkit Selettra with curve, but it's a lot more expensive then the HPI.
MotoPlat Electronic Outer-rotor
Consists of:
Rotor
Stator
External coil
Light coils
+ No contact-points
+ 2 light coils
- Heavy rotor
- 40 year old design
- Discontinued
Special points of interest:
MotoPlat has only made this ignition for a couple of years. The factory is long gone (Bankrupt).
It out-performs the stock Puch ignition, however the flywheel is kind of heavy.
This ignition doesn't have contact-points or CDI, but works with an external coil & 2 light coils.
