If your new Yamaha FZ S V3.0 leans to the right when you release your hands from the handlebar while on a flat road and in a centered sitting position, it is not considered normal. It is possible that there could be an issue with the bike's alignment or suspension.
Here are a few things you can check:
Tire pressure: Make sure both the front and rear tires are inflated to the recommended pressure as specified in the owner's manual. Uneven tire pressure can affect the bike's balance.
Suspension: Check if the suspension components are properly adjusted and functioning correctly. If the suspension is imbalanced or misaligned, it can cause the bike to lean to one side.
Wheel alignment: Ensure that the front and rear wheels are aligned properly. Misaligned wheels can lead to instability and uneven handling.
Weight distribution: Check if there is any additional weight or accessories on one side of the bike that could be causing the imbalance. Make sure the bike is evenly loaded.
If you have already checked these aspects and the issue persists, I would recommend taking your Yamaha FZ S V3.0 to an authorized Yamaha service center or a qualified mechanic to have it inspected. They will have the expertise to diagnose and address any potential alignment or suspension issues that may be causing the bike to lean to the right.
