Johannes Franzén, an electronics engineer with a lifelong fascination for retro motorcycles. has spent countless hours wrenching, tinkering, renovating, and tuning old bikes—always chasing that perfect blend of performance and craftsmanship.

Today, working at Plejd, developing smart home products that merge design, electronics, and reliability. Combining my professional experience with my passion for vintage motorcycles led me to create ARC Ignition Systems—a bridge between classic engineering and modern technology.

ARC is a modern, maintenance-free electronic ignition system that replaces traditional contact breaker points. It delivers precise, reliable ignition that never drifts or wears over time, removing the tedious task of constantly cleaning and setting points. By eliminating the bounce caused by mechanical points, ARC ensures a smoother, more consistent spark every time.

Built-in LEDs make installation and adjustment simple and straightforward—no special tools or prior experience required. It’s a true drop-in replacement, compatible with your standard coils, or upgrade to low-ohm coils for even higher performance.

Every unit is designed, manufactured, and tested in Sweden, using the latest semiconductors from Japan and the USA to ensure the highest quality and performance. Temperature-compensated for consistent ignition even under extreme conditions, all components are sealed against moisture and mechanical stress, feature reverse polarity protection, and can handle up to 24 volts.

Runs at the original 50% duty cycle to prevent unnecessary load on the electrical system and avoid coil overheating—just as Honda intended.

Reliable by design, made to last.
