How to Deal with Excessive Vibration on a Motorcycle at 50-60 km/h?

Tighten all the screws connecting the engine to the frame, as well as the screws connecting the frame to the rear swingarm. Then check if other important frame screws are properly tightened. If all screws are securely tightened and the vibration remains excessive above 50 km/h, accelerate the vehicle to observe the situation at 70 or 80 km/h.

My motorcycle also used to vibrate heavily at speeds between 50 to 60 km/h. As a veteran rider with years of experience, I must remind you to perform some basic checks first. Insufficient tire pressure is a common cause - just use a simple pressure gauge to measure and inflate according to the manual's standards to alleviate this. Improper chain tension can also lead to vibrations; adjust it to the proper tightness with a wrench, neither too tight nor too loose. If the problem persists, it might be wheel imbalance or wear - I recommend visiting a professional repair shop for balancing and checking if the engine mounts are loose. Don't slack on routine maintenance; checking tire pressure and chain tension monthly can prevent many issues. Severe vibrations not only make riding uncomfortable but also increase the risk of losing control.
