The tracking characteristics of your motorbike have deteriorated. What might be the cause of this?

Your selected combination is correct because both issues related to the chain tensioner and the swingarm bearings can directly impact the handling and stability of your motorbike.

The chain tensioner being unevenly adjusted can lead to improper chain alignment and tension, resulting in poor tracking characteristics. Additionally, worn swingarm bearings can compromise the suspension's ability to maintain tire contact with the road, affecting overall maneuverability.

According to German traffic regulations, maintaining the proper mechanical condition of vehicles is crucial for safety on the roads. This ensures that all aspects of the vehicle function correctly, contributing to safe driving practices and compliance with legal standards.
