Rated performance

Ventus lists 60.3kW peak at 72V and 81kW at 96V. Output depends on the complete electrical system and tune.

Surface Preparation

  • Thoroughly clean the application area using isopropyl alcohol or a mild, residue-free cleaner.
  • Remove all dirt, grease, wax, and dust.
  • Ensure the surface is completely dry and smooth before applying.

Positioning the Decal

  • Before removing the backing, test-fit and align the decal on the surface.
  • Use masking tape to hold it in place if needed.
  • Once aligned, flip the decal up and slowly peel away the backing paper.

Applying the Decal

  • Starting from the center, press the decal down gradually, working from the center outward.
  • Use your hand, a soft squeegee, or a microfiber cloth to remove air bubbles as you go.
  • Apply firm, even pressure across the entire decal.

Post-Application & Heat Treatment

  • Once applied, go over the decal again with firm pressure to ensure full contact.
  • Carefully heat-treat the decal using a heat gun or small torch to activate the adhesive and help the vinyl conform to the plastic. Use low heat and keep the heat source moving at all times.

    Do not overheat — excessive heat can burn, distort, or damage the vinyl and laminate.
  • The vinyl should become slightly warm and more flexible, not hot.

This heat-treat step is critical for long-term adhesion, especially on curved plastics and high-wear areas.
