Why my bike vibrates a lot when I accelerate

Among all the technical problems that a motorcycle can have, one of the most common is the excessive vibration that occurs especially when the vehicle accelerates. This vibration that originates especially when we increase the speed of the vehicle can be caused by a variety of reasons that can be from an easy setback to a problem much more serious than we imagined.

Although the most advisable is to take the motorcycle to a mechanic to inspect it and tell you exactly the problem it has, in the following article we give you some of the main causes that cause this vibration. If you want to know why my bike vibrates a lot when I accelerate, keep reading these lines.

Badly balanced tires

One of the reasons why a motorcycle has those annoying vibrations when accelerating is because the tires of the vehicle may not have the proper balance. To verify that the problem of the vibrations when increasing the speed is due to this mechanical problem, observe if these two signs are mainly present :

  • When you accelerate the motorcycle, excessive vibration occurs in a certain speed range (generally between 80 and 140 km / h).
  • The drawing of a well-balanced wheel wears out regularly. Pass your hand over the entire wheel to check if there is any step for your drawing.

If so, you should go to a mechanic to repair this problem, or to even change the wheels of your motorcycle. You may also be interested in this other article on How to change a motorcycle tire.

Motorcycle bearings in poor condition

The bearings of a motorcycle are devices that are found in both the front wheel and the rear of the vehicle to reduce the friction that occurs in the rotation of a particular piece on the axle. To minimize this friction, the bearings consist of two circular tracks and certain rolling elements such as barrels, needles and cylinders.

Other causes of why my bike vibrates a lot when accelerating is that these bearings are in very bad condition, so that by not reducing the friction of the parts would give these annoying movements in the vehicle. To check that the bearings are in good condition follow these steps:

  1. Leave the wheels suspended in the air, either with a central stand or directly hanging the vehicle.
  2. Twist the direction until you reach the top of one of the sides.
  3. Leave the fork fastened in this position while you grab the tire and try to move it from one side to the other.
  4. If you can move the wheel without any effort, it means that the bearings are not in good condition and, therefore, it is essential to replace them.

Damaged brake discs

The brake discs of a motorcycle are devices that, by friction with the brake pads, ensure the reduction of the speed of the wheels of the vehicle until it stops. Although they are made of a material with a lot of resistance, the brake discs end up wearing out and can cause some mechanical problems such as the excessive vibration of the wheels when we accelerate the vehicle.

To know if the brake discs are in bad condition, we will have to observe if in the thickness of the device we find some negative indications such as scratches, curvatures or cracks . If we have found some of these signals, the next thing will be to know what thickness limit is appropriate according to the manufacturer of the device. If you do not comply with the instructions described by the manufacturers of this material, it will be necessary to replace the brake discs of your motorcycle .

Badly adjusted chassis

The chassis or frame of a motorcycle is a structure that serves as a link for the other parts of this vehicle, such as the brakes, the engine, the fuel tank and the wheels, among others. In addition to being the most basic pillar of any motorcycle, the chassis is also an element that is responsible for joining the steering fork with the pivoting axle of the rear, which ensure that the vehicle does not suffer irregularities during accelerations, braking or inclinations, among other things.

If the vibrations when accelerating have occurred since you made some modification on your bike, it is likely that the main reason why these irregular movements occur when increasing speed is because the chassis of your vehicle is poorly adjusted, either because the time to screw it was too loose or tighter than normal . Because of this, the vehicle's engine transmits these excessive vibrations on a motorcycle every time you try to accelerate.

How to remove vibrations from a motorcycle

To know how to remove the vibrations on a motorcycle, first you have to know why the bike trembles . Sometimes it is not easy to detect the problem, so if after following the steps that we have indicated above you have not found the reason for the vibrations of your motorcycle, the best thing is that you take it to the mechanic to solve the problem.

However, if you think the bike vibrates when accelerating due to one of the reasons above, you can try to fix it yourself. However, for optimal results, it is best to have the help of a specialist .
