Minarelli Horizontal Water Pump Cover – Electric Conversion

Engineered for Minarelli horizontal engines running an electric water pump conversion, this custom 3D-printed cover replaces the original mechanical water pump housing while ensuring proper cooling airflow to the racing ignition system.

Instead of sealing off the area, the integrated honeycomb grille is purpose-built to maintain consistent airflow over the ignition, helping reduce heat buildup during high-performance riding. This makes it ideal for tuned or race setups where reliability and cooling are critical.

The design combines function with a clean, aggressive look. A raised centerpiece logo adds depth and identity, while the outer ring is engraved with the phrase:
"Where scattered parts turn into dreams of glory" — a fitting statement for any custom build.

Key Features:

  • Designed for Minarelli horizontal engines with electric water pump setups
  • Replaces the stock mechanical water pump cover
  • Maintains airflow for effective ignition cooling
  • High-flow honeycomb grille structure
  • Lightweight, durable 3D-printed construction
  • Custom raised emblem centerpiece
  • Dual-color finish (matte black with red accents)
  • Uses original mounting points for easy installation

Ideal for:

  • Liquid-cooled Minarelli builds converted to electric water pumps
  • High-performance and racing setups
  • Custom scooter projects balancing cooling and aesthetics

A functional upgrade that keeps your ignition cool while adding a unique, custom finish to your engine setup.
