Description
Selettra internal rotor ignition by ITALKIT for 4-stroke pitbikes
High-performance ignition with an excellent price-performance ratio.
The Italkit racing ignition for pit bikes with 4-stroke engines is designed exclusively for use in competition and on closed racetracks. It has no 12 V output and therefore does not supply power for electrical accessories such as headlights, on-board electronics or electric pumps. This model was developed in collaboration with SELETTRA and is the perfect ignition for racing and ambitious tuners!
italkit selettra - Top performance and optimum ignition timing
This is an analogue internal rotor ignition with fixed ignition timing, which offers high performance and a perfect balance to minimize vibrations. This ignition is ideal for tuned setups and retains its stability up to 27,000 rpm.
Technical highlights Italkit Selettra high-end ignition
- Wide speed range: Operation up to 27,000 rpm, ignition spark starting from as low as 400 rpm.
- Better response: Low rotor mass of only 350 g reduces the flywheel inertia allowing the engine to rev up faster.
- Crankshaft relief: Reduced stress on the crankshaft minimizes torsional oscillations / vibrations.
- Efficient cooling: Integrated fan on the rear of the rotor ensures optimum heat dissipation.
Scope of delivery Italkit Selettra

- Base plate for pit bikes
- Screws and washers: DIN 912 M5x35, M5x20, M6x25 bolts and DIN 125 M5 washers.
Inner Rotor Ignition
An internal rotor ignition is a racing ignition designed to increase performance. Inner rotor ignitions are designed for motorsports and competition, in rare cases they also provide power for vehicle lighting. (e.g. the MVT ignition).
Advantages of an internal rotor ignition
Inner rotor ignitions are the ultimate choice for the race track, they are however not really suitable for street use.
The compact and lightweight internal rotor puts less weight on the crankshaft and allows for quick revving, very high engine speeds and an enormous power increase at high rpm.
Another advantage is that this type of ignition is less susceptible to moisture than standard ignitions.
Tip: You may want to consider a tuning ignition cover with additional holes / cutouts to improve ventilation.
Disadvantages of an internal rotor ignition
RPMs increase faster due to the lower mass, this will affect torque at low RPMs, though. Therefore, internal rotor ignitions are only worthwhile for racing, because on the racetrack you'll constantly stay at high engine speeds.
Installing and adjusting an internal rotor ignition
Installing an internal rotor ignition requires technical knowledge and careful adjustments to keep the engine running optimally and really optimize performance. We recommend our tutorial to learn how to install and adjust an internal rotor ignition.
