This is a list of almost every ignition you can fit onto your Puch engine.

This list is sorted by price-range.

Stock Puch Maxi points ignition

The stock Puch Bosch/Iskra ignition.

There are 2 different versions of this ignition:

  • Newer version: Primary coil -> Secondary coil -> Sparkplug
  • Older version: Ignition coil -> Sparkplug

Found on:


Consists of (New model):

  • Baseplate
  • Flywheel
  • Contact-points
  • Condenser
  • Primary coil
  • Secondary coil
  • Light coil

+ Easy to install
+ Good light coil (6v 17W)

- Contact-points (Sometimes not very reliable)

- Doesn't work well above 12.000 RPM
- Heavy flywheel (Bad throttle response)

Special points of interest:

  • There are cheap imitation coils, contact-points and condensers available.
  • Original Bosch parts are also available. Original Bosch is preferred over imitation, especially with contact-points and condensers.

Puch Z-one CDI Ignition

The original Ducati CDI ignition for Puch Z-one.

Consists of:

  • Baseplate
  • Flywheel
  • Primary coil
  • Secondary coil
  • CDI

+ Very good light coil (12v 35W)

- Doesn't seem to last very long
- Hard to tune
- Heavy flywheel (Poor throttle response)

Special points of interest:

  • Was only stock on Puch Z-one

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

Ign4.jpg Ign5.jpg 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.
