N2  - Thailand faces a significant issue with motorcycle use, with over 22 million registered  vehicles in 2023, accounting for 51% of all registered vehicles. Motorcycle crashes  account for 80.4% of road traffic fatalities, with the highest death rate among ASEAN  countries. A study aims to examine the relationship between rider characteristics and  actual riding behavior, and to assess what risk behavior factors were associated with  self-reported crash involvement and fine offenses.   This study focuses on the risk behavior, aggressive behavior, and risk perception of  young motorcyclists in Thailand using focus groups and questionnaires. The  questionnaire consisted of four main sections: personal, vehicle, and riding information,  self-reported crash involvement and fine offenses, perception of unsafe riding  behaviors, and riding behaviors.Data analysis was performed using the STATA program, including descriptive  statistics, principal component analysis, Pearson's correlation coefficient, multiple  linear regression, and binary logistic regression.   The study found that 70% of young riders under 18 use motorcycles over the legal  engine size, often report unsafe modifications, and lack proper licenses. Most riders use  rear-heavy braking due to misinformation or lack of proper riding knowledge. Young  riders are more likely to engage in speed-related risky behaviors, such as rider anger,  unsafe surfaces, and unhelmeted passengers. They also reported higher traffic errors,  speed violations, stunts, and safety violations. Young riders also reported higher  aggression scores, indicating greater emotional reactivity and impulsive behavior. They  were more likely to report crashes and near-crashes than adult riders, with higher speed  violations and past traffic fines. Young riders aged 18-24 were more likely to report  fines than adult riders
