If plastics are used
Before starting, remove any remaining dirt with a specific silicone remover (absolutely avoid thinner or acetone). Then wash thoroughly with water and neutral soap, carefully drying the entire surface.

If the plastics are new
Even pieces fresh out of the packaging contain manufacturing residues. For this reason, it's important to wash them with soap and water and then dry them thoroughly.

Temperature is crucial: ideally, around 20°C. Start applying the adhesive from one end (or from the center for smaller pieces, like the front panel). Always work from the inside out to avoid bubbles.
For trickier areas (curves, edges, or folds), you can use a household hair dryer to slightly soften the design. However, keep a distance of about 10 cm and don't overdo the heat: excessive heating will ruin the design.

After completing the job, let the motorcycle with the graphics applied rest for at least 24 hours in a warm environment (above 20°C). The 24-hour wait ensures that the decal bonds properly and follows the shape of the plastic. Keep in mind that the film tends to flatten, so it's helpful to go over it occasionally with your hand, applying gentle pressure.
