Special points of interest:

- Heavy flywheel (Poor throttle response)
Special points of interest:

Sparcon Contact-points Replacement
A sort of module that attaches to the baseplate to replace condenser and contact-points.
+ No contact-points
+ Works above 12.000 RPM
- Doesn't seem to last very long
- Not tuneable
Special points of interest:
- One of a kind. Doesn't work with every engine the way it should.
- Price is around $20 which is a lot for a device that doesn't work with every setup.
HPI CDI Inner-rotor
HPI 2005
Horse Power Ignition inner-rotor with "curve"*
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.
Brands:
- Italkit Selletra
- Malossi Selletra
- TNT Selletra
They are basically all the same.
- Only Malossi has an Eprom. That's a self-programmable CDI so you can make your own curve. It is expensive however.
There's also a digital Italkit Selettra with curve, but it's a lot more expensive than the HPI.
MotoPlat Electronic Outer-rotor
- 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.
