The motorcycle seatpost is an indispensable element for a reliable and safe motorcycle ride. We tell you what it is, what it is used for, what types exist and how you can check if it is damaged.
The motorcycle seatpost is an indispensable part in the operation of the vehicle as it is responsible for connecting the front fork to the motorcycle chassis, allowing the steering to turn. For this reason, it is essential when it comes to promoting performance and safety on the motorcycle.
Parts of the seatpost
The seatpost is composed of two parts: the upper seatpost and the lower seatpost, both of which ensure the proper functioning of the motorcycle.
- Upper seatpost: it is responsible for connecting the handlebars to the fork of the motorcycle.
- Lower seatpost: it is in charge of transmitting the steering.
Both elements are equally important to provide stability and safety to the motorcycle, so their maintenance is essential.
Types of motorcycle seatpost
Not all seatposts are the same and in the market you can find different parts of this type that will adapt to the specific model of motorcycle:
Conventional seatposts
They have the fork mounted at the top and on it, the handlebars of the motorcycle. It is the most common type in off road and street vehicles. They are easy to repair and manufacture. They provide good balance, quick steering response and are comfortable. Their main disadvantage is that they are rigid, so in extreme conditions they can deform or bend.
Inverted seatposts
Also called inverted suspension, they have a fork mounted on the lower part of the handlebars and the handlebars on the upper part of the fork. This is the design most commonly used on racing or motocross bikes, they are more resistant and flexible.
Why are they so important?
The seatpost is an essential element as it has a significant impact on different parts of the motorcycle. This part is in charge of controlling the angle of the bike and thus giving stability to the vehicle. Damage or misalignment can cause the steering to not act as it should, making it less precise and increasing the risk of accidents.
The bike’s suspension is also affected by the function of the seatpost. If this part is not in good condition, it will cause the shock absorption of the suspension to be inadequate. This makes riding uncomfortable, but above all more dangerous.
What problems does it usually present?
Problems in the seatpost of the motorcycle are usually easy to identify as they are accompanied by vibrations in the handlebars and failures in other parts of the vehicle. The most common failures in this part are accompanied by increased stiffness or difficulty in controlling the bike’s steering. If you notice that the steering becomes stiffer or the handlebars vibrate while riding, it is advisable to visit a workshop as soon as possible so that it can be checked and repaired.
