Ignition SIP VAPE Road "Black Edition" DC for Vespa PK50-125, PK XL/XL2, ETS and 100 Sport - 12 V / 110 W, contactless, bright light, stable DC on-board power supply

The SIP VAPE Road "Black Edition" DC is the modern conversion for all Vespa PK50-125, PK XL/XL2, ETS and 100 Sport with large crankshaft cone (M12). It combines a contactless high-performance ignition with a powerful 12 V DC electrical system. Plenty of light output is available even at low engine speeds, while the full-wave DC system enables a stable power supply via the battery - ideal for powerful headlights, indicators, chargers and other accessories.

12 V DC / up to 110 W (at approx. 6,000 rpm) Bright light even when idling (~80 W @ ~2,000 rpm) Contactless, maintenance-free ignition Static ignition timing (road version) Full-shaft regulator for battery operation CNC aluminium fan wheel, black anodized Pole wheel + fan wheel approx. 1,390 g, balanced Made in Europe by VAPE

Highlights

Whether standard engine or tuned setup: The VAPE Road "Black Edition" DC takes the electrics of modern PK and ETS models to a new level. The contactless ignition ensures a powerful spark and spontaneous starting, while the DC on-board power supply system provides evenly regulated 12 volts for all consumers - even at low engine speeds and, thanks to the battery, even when the engine is not running. The black anodized CNC fan wheel ensures a high air flow rate and fits in perfectly with discreetly upgraded vehicles.

Quality and design

The system is manufactured entirely in Europe and each unit is 100% function-tested. The one-piece pole wheel with 12 magnets is precisely balanced and matched to the large PK/ETS cone (20/20 or 24/25 mm, M12). The CNC-milled aluminium fan wheel of the "Black Edition" is anodized black and combines high cooling performance with a flywheel mass that matches the driving mode.

Conversion from contact ignition to contactless DC system

The VAPE replaces the complete contact ignition system including alternator. Strong permanent magnets in the pole wheel generate a high ignition current and sufficient power for the vehicle electrical system even at low engine speeds. The engine starts more easily, contact maintenance and capacitor replacement are permanently eliminated. Thanks to DC regulation, voltage peaks are absorbed cleanly and the on-board voltage is kept stable at 12 volts.

DC on-board electrical system and power supply

In contrast to the classic AC system, the DC version supplies all consumers via the battery. The alternator feeds the battery via the full-shaft regulator, from where the headlights, horn, indicators and additional consumers (e.g. USB charger, navigation system) are supplied.

Stable on-board voltage, less flickering and dips at idle speed.
Power supply also possible when the engine is switched off (e.g. hazard warning lights, navigation system, cell phone charging).
Ideal for powerful headlights (e.g. 60/55 W) and modern LED/additional consumers.
Full-wave regulator reduces the load on the bulbs and the on-board electrical system.

Ignition timing

The Road version is supplied with a CDI with static ignition timing. This design harmonizes with both close-to-production engines and also with highly performance-enhanced road engines. Optionally, a dynamically adjusting CDI can be fitted if a very speed-oriented racing set-up is used.

Installation and ignition setting

The ignition is fitted to the original mounting points. Thanks to clear markings, the ignition timing can be set without a strobe. It is important to ensure that the earth is properly routed and that the cables are cleanly laid and protected against chafing. After the first 50-100 kilometers, the fastening screws should be checked and retightened if necessary.

Pole wheel and fan wheel

As in the original, the pole wheel has a single groove, which virtually eliminates the possibility of incorrect installation. The flywheel matching the engine is defined by the aluminum fan wheel. In the Black Edition, a black anodized CNC fan wheel with optimized blade geometry is used. This combines high cooling performance, clean response and smooth running.

Important for DC conversion: wiring harness

Many PK models were delivered from the factory with decentralized electrics or separate coils for the lighting and charging circuits. The VAPE, on the other hand, works centrally: all coils feed the regulator, from where they are distributed to the DC on-board network. An adapted wiring harness is therefore highly recommended for a clean DC conversion - especially because old wiring harnesses are often corroded internally and have increased contact resistances.

You can find suitable conversion wiring harnesses for PK/ETS models in our store. They are clearly labeled and make it easier to convert to a modern DC wiring system.

Upgrade for Vespa PK and 100 Sport (large cone)

The DC version of the SIP VAPE Road "Black Edition" is ideal for all PK models and the 100 Sport with large crankshaft cone (M12). The cleanly balanced flywheel mass of approx. 1,390 g protects the crankshaft and noticeably improves the response behavior - especially with performance-enhanced engines.

At the same time, there is enough electrical power available to safely operate powerful headlights, indicators and modern comfort consumers.

The DC version is designed for Vespa PK50-125, PK XL/XL2, ETS and 100 Sport with large crankshaft cone (Ø20/20 mm, M12). The relevant types and chassis number ranges are listed in the compatibility table. If in doubt, take a look at the crankshaft nut (M12 = large cone).
The DC on-board electrical system supplies all consumers via the battery. This provides a very stable on-board voltage, which is particularly useful for powerful headlights, indicators, LED conversions and additional consumers (e.g. USB charger, navigation system). In addition, the horn and lights remain fully usable even at low revs or shortly after revving off.
Strictly speaking, a conversion can also be adapted using the existing wiring harness. In practice, however, old wiring harnesses are often corroded internally and are not designed for a central DC wiring system. We therefore strongly recommend installing a suitable conversion wiring harness for the VAPE conversion. This ensures reliable earth connections, low contact resistances and proper functioning of all consumers.
Yes. The VAPE ignition is designed for powerful two-stroke engines and has also been used successfully on tuning setups for years. The powerful ignition spark, the stable on-board voltage and the cleanly balanced flywheel mass are particularly advantageous for high-speed engines.

Note: A clean ground connection, intact plug connections and a correctly dimensioned battery (capacity and condition) are essential for long-term trouble-free operation.
