Magneto for Off-Road Motorcycle (Horizontal Engine)

⚡ Lightweight Flywheel · Built-in Magnetic Rotor · High Performance Upgrade

• Lightweight Design: Built-in magnetic rotor structure eliminates original flywheel weight for quicker engine response.
• High RPM Capability: Supports up to 15,000 RPM for racing applications.
• Adjustable Ignition Timing: Allows you to set and build in timing into your motor.
• Kick Start Only: Designed specifically for kick-start models – not compatible with electric start engines.
