upside down fork vs telescopic

Everyone is familiar with suspension and is aware that it is one of the most crucial parts of a car. That affects how your automobile or motorcycle handles so greatly. Now that the automobile suspension is understood let’s concentrate on the motorbike front suspension.

There are two different forms of front suspension for motorcycles, depending on their use:

  1. Telescopic suspension
  2. Upside-down suspension

What is Motorcycle Suspension?

Let’s examine how motorcycle suspension operates before delving into the different varieties. A spring and a damper are the two main components of a front suspension system.

  • The amount of compression is determined by the spring.
  • On the other hand, the damper controls how quickly the entire system reacts. When compressed, the oil-filled dampers offer resistance.

Interesting fact: The components of conventional telescopic and USD suspension systems are the same. The reason for selecting USD over telescopic lenses or vice versa is now under doubt.

Telescopic Suspension in Motorcycles

The majority of motorcycles on Indian roads have telescopic suspension. They are primarily motorcycles used for commuting.

  • Outer and inner tubes house all the mechanisms and make up a telescopic suspension.
  • The system comprises a spring and a damper that oppose each other using fork oil.
  • The slider bar of the inner tube is fastened to the triple clamp in this kind of suspension. Well, the handlebars are mounted to a component called a triple clamp.
  • The largest barrel or outer tube is on the wheel’s lower side.
  • The telescopic suspension has a weakness in this area. In other words, the wheel carries most of the suspension system’s weight. Because of this, steering or changing lanes is challenging.

Why Are They Used Then?

  • The design and production costs of telescopic suspension are lower.
  • If something is wrong, the suspension is simple to fix.

Hence, as commuter motorcycles aren’t designed to be driven hard, they typically have telescopic suspension. Also, they must quickly and abruptly change directions. In addition, the telescopic suspension is also cost-effective due to its low cost. This suspension hampers high-end motorbike performance.

Upside-Down Fork (USD) in Motorcycles

This suspension type also has an inner tube, also known as a slider bar, and an outer tube, also known as a primary barrel.

  • But where they are located makes a difference. The sliding tube for USD suspension is located on the motorcycle’s wheel’s lower side.
  • The triple clamp is connected to the primary barrel. As a result, the triple clamp can support the bulk of the suspension weight. This mount supports the majority of the suspension system’s weight.
  • The motorcycle’s configuration makes it maneuverable and agile. It also enables the motorcycle to be handled with agility and precision.

Why Utilise USD Suspension?

Only the most expensive and powerful motorcycles can have this kind of suspension. Fast motorcycles ultimately revolve around turning speeds and blazingly quick direction changes. Hence, the USD fork enables the rider to get the most performance out of the motorcycle without sacrificing handling. There is a price for this.

  • COST, exact USD cost, front forks cost much more than standard telescopic suspension.
  • However, while these updated USD forks can absorb more bumps, the suspension is more vulnerable to damage.

Upside Down Fork vs Telescopic Suspension

When the bike’s power and engine capacity are low and riding accuracy is unnecessary, telescopic forks are used. Commuter or sporty commuter bikes, like the Hero Splendor and Bajaj Pulsar 220F, can readily acquire telescopic forks.

Even though sports motorcycles like the KTM RC or Duke series are built to endure harsh turns, the company had to equip them with high-quality USD forks. As previously stated, its USD forks significantly increase the price of the motorcycle, as evidenced by the cost discrepancy between KTM and other Indian manufacturers.

Several powerful bikes don’t come equipped with USD forks. This is because motorcycles are positioned in markets that require reasonably priced vehicles with respectable performance.


Telescopic fork vs usd fork which is better. There are two types of suspension: telescopic forks and USD (Universal System of Damping) forks. You may have gathered from looking at upside-down fork vs telescopic the USD forks have a secondary spring and damper assembly. On the other hand, telescopic forks operate on a more straightforward concept.
