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.

I've dealt with quite a few motorcycle vibration issues. From a technical perspective, common causes include tire wear or uneven tire pressure, improper chain tension, loose engine mounts, or bent wheel axles. You'd better first check the tire pressure yourself to ensure both sides are equal; adjust the chain tension using a specialized tool, making sure it doesn't drag on the ground or is overly tight. If the vibration persists, inspect whether the wheel axle or engine mounts are damaged – simple screw tightening can solve minor issues. Safety first: avoid high-speed riding when there's a malfunction, and promptly visit a repair shop for professional equipment diagnosis to prevent more severe damage.

Last time I rode my motorcycle up to 60 km/h, the vibration was really strong. I just learned to ride a few months ago and got a bit panicked at that moment. I asked a knowledgeable friend to take a look, and he said it's most likely due to underinflated tires or a loose chain. Simple solution: Buy a portable air pump to inflate the tires properly and adjust the chain tension a bit tighter. If that doesn't work, it might be a wheel issue, and you'll need professional help. Don't force yourself to tough it out—ride at low speed to a safe place first and check. Such minor adjustments usually solve the problem. Riding a motorcycle is all about fun, but safety comes first.

If the motorcycle exhibits noticeable vibrations at speeds of 50-60 km/h, as a safety-conscious veteran rider, I recommend stopping immediately to investigate. Start with the easiest checks: whether the tire pressure is even, if the chain tension meets specifications, and if the engine mounts are secure. If there's no improvement, the issue may stem from wheel imbalance or severe wear—don't overlook this risk. Visit a reliable repair shop promptly for a comprehensive inspection, as excessive vibration can impair handling and increase accident risks. Remember, regular basic maintenance is far better than waiting for problems to arise before fixing them.
