My 2003 Honda accrod front vibrates at 55to 60 kph. Has anyone know why would that be.

 

If it always vibrates at the same speed regardless of engine RPM it is probably a worn CV shaft joint.

 

Tires out-of-balance, maybe lost a wheel weight? Swap wheels front to back to see if the vibration disappears or changes.

 

Worn CV joint often will vibrate more when accelerating, less when coasting, even at the same speed.

Wheel balance depends more on speed, less on acceleration. But the easy way to check wheel problems is to swap them front-to-back like Roader says.
