MVT Premium Internal Rotor Ignition with Light – Vespa PX, DN, and TX 125–200

Performance-oriented internal rotor ignition with 55 W light output and analog variable ignition timing for Vespa large-frame engines. The MVT Premium PREM42 combines the advantages of a lightweight internal rotor with an integrated power supply for the vehicle’s lighting.

With its CNC-machined internal rotor weighing only about 250 g, the MVT Premium offers exceptionally direct response and enables rapid changes in engine speed. The variable ignition timing allows for speed-dependent adjustment of the ignition timing.

Unlike pure racing ignition systems without a lighting output, the MVT Premium features an integrated lighting function with 55 W of power. This makes it suitable for applications where, in addition to a performance-oriented ignition system, power for the vehicle’s lighting is required.

Product Features

  • Internal rotor ignition: Lightweight, CNC-machined rotor for direct response
  • Variable ignition timing: Analog, RPM-dependent adjustment of the ignition timing
  • 55 W lighting output: Integrated power supply for vehicle lighting
  • 42 kV discharge voltage: High-performance high-voltage ignition
  • High RPM stability: Designed for speeds up to 22,000 RPM
  • Cooling turbine: Assists with heat dissipation from the engine
  • Inertia counterweight: Additional flywheel mass to increase the moment of inertia
  • Expandable: Can be optionally combined with an MVT EPROM multi-curve digital controller

Technical Specifications

  • Manufacturer: MVT
  • Product Series: Premium
  • Part number: PREM42
  • Design: In-rotor ignition with light function
  • Ignition adjustment: Analog, variable
  • Light output: 55 W
  • Discharge voltage: 42 kV
  • Maximum RPM: 22,000
  • Operating range for racing engines: 7,000–15,000 rpm
  • Rotor weight: approx. 250 g
  • Inertia counterweight: +60%
  • Cooling: Cooling turbine with high heat dissipation

Inner Rotor and Responsiveness

A key advantage of the MVT Premium is its lightweight inner rotor. Compared to heavy conventional flywheels, the lower rotating mass reduces the engine’s inertia. This allows the engine to rev up faster and respond more immediately to throttle inputs.

The additional inertia counterweight allows for adjustment of the flywheel mass. This enables the system to be configured according to the desired engine characteristics.

Variable Ignition Timing

The MVT Premium uses an analog variable ignition timing system. The ignition timing is adjusted based on engine speed, allowing the ignition to be tailored to different operating conditions.

For more advanced tuning, the system can be optionally upgraded with an MVT EPROM multi-curve digital computer. This allows for the use of different ignition timing curves tailored to specific engine designs.

Integrated Lighting Function

The integrated lighting coil provides 55 W of power. This allows the ignition system to power the vehicle’s lighting in addition to its primary ignition function.

Important: When retrofitting, the electrical power consumption of the connected loads must be taken into account. The 55 W lighting output must be considered when planning the vehicle’s electrical system.

Scope of Delivery
