Congradulations for your new ride. Masha Allah. Drive carefully and never forget "Safety First". I read your thread with intrest as it shows some information on vibration, Many threads on YBR just mention Smooth ride and they do not elaborate.
Once the "Breaking In" is over please tell us when , or at what RPM the vibration starts. Your foot pedals or handle bar or the rear view mirrors start shaking /vibrating. This information needs both parameters i.e. RPM and Speed when vibration begin and when, if ever, it reduces at higher RPM.
This information is important for me to decide weather to buy or forget YBR
