In the United Kingdom, the minimum age requirement for riding a motorcycle on a public road is 17 years old for most categories of motorcycles, including those with engine displacements of 1000cc or higher. However, riding a motorcycle on a track in a controlled environment may have different rules and regulations.
Track days and racing events on closed circuits are typically organized by specific track operators or event organizers. These organizations may have their own age restrictions and requirements for participants. It's important to consult the specific track or event organizers to determine their age policies regarding riding motorcycles with 1000cc or higher engine displacements.
Additionally, even in a controlled environment such as a racetrack, safety regulations and insurance requirements may still apply. Some organizations may have specific rules and criteria for allowing younger riders to participate in track events, which could include additional training, supervision, or consent from a parent or guardian.
To ensure accurate and up-to-date information regarding age restrictions and regulations for riding a motorcycle on a track in the UK, it is best to reach out directly to the track operators or event organizers for their specific policies.
