Riding a two-wheeler creates a continuous airflow; the faster you go, the more this airflow draws heat from your skin, lowering the perceived temperature (wind chill).
The table below shows this apparent temperature for four common speeds, from 50 km/h to 130 km/h. It is a simplified model based solely on riding speed and outdoor temperature.

Key points to interpret the figures

1- Ambient wind not included – A headwind will worsen the cold; a tailwind may slightly reduce it.

2- Humidity – Humid air (or wet clothing) increases heat loss.

3- Clothing insulation – Windproof and insulating layers greatly alter how the cold feels.

4- Exposure time – The longer the exposure, the more cold “builds up.”

5- Individual variability – Body shape, health, and acclimatisation all affect cold tolerance.

These values help anticipate the intensity of cold depending on speed, so you can adjust your gear, breaks, and riding duration. They serve as a guideline; actual conditions will always depend on wind, humidity, clothing insulation, and each rider's resilience.
