Why USD Forks Matter: Exploring the Impact on Bike Performance

If you are a motorbike enthusiast, your dream bike is the one that gives you undisputed performance on any kind of road: smooth or bends, right? But what contributes to this performance is the bike's suspension! While both suspensions of the bikes: rear and front, have distinct functions, the front suspension has extra duties like steering and absorbing the extreme stress that abrupt braking places on it. Since the late 1930s, telescopic fork suspension has been employed in bikes. However, realizing the benefits of an upside-down fork, the suspension game is slowly shifting to upside-down forks! But why is it? Let us get into the blog and explore why USD forks matter, unraveling their impact on bike performance.

Telescopic Forks and USD Forks: What exactly are they?

Since the 1930s, telescopic forks have been the most popular front suspension for motorbikes. They consist of two parallel tubes, with one sliding inside the other. While the outer tube is joined to the bike's steering head, the inner tube supports the wheel and is connected to the frame. Telescopic forks cannot meet the demands of these extreme vehicles regarding severe applications like rally bikes and super track bikes.

USD forks, on the other hand, feature an inverted configuration with the smaller diameter tube on top and the bigger diameter tube at the bottom. USD forks offer the bike a higher capacity to travel over bumps and meet the requirements of the bike, especially under extreme conditions. The USD fork has gained popularity for high-performance street bikes after being originally used for racing motorbikes in the late 1980s.

Today, many bikes in Nepal are equipped with advanced USD forks. Among the leading competitors in Nepal, the prestigious Bajaj Nepal has seized the lead by significantly improving its bikes. With the introduction of models Bajaj Pulsar NS200 FI Dual ABS BS6 and Bajaj Pulsar NS160 FI Dual ABS BS6 Bajaj proudly asserts that they are the most excellent bikes in Nepal by fitting themselves with advanced USD forks. This is in addition to their existing popular models Bajaj Dominar 400 BS6 and Bajaj Dominar 250 BS6, which include the same advanced USD forks.

Why Do USD Forks Matter in bikes? 4 Reasons

More Rigid Setup

The greater stiffness of USD forks is one of its key benefits. The stanchion tubes of conventional telescopic forks are thinner and less robust, which can lead to flexing and bending in harsh situations. The bigger diameter tube at the bottom of USD forks creates a more rigid configuration that decreases flex and enhances stability and rider feel.

Reduced Unsprung Weight

The decreased unsprung weight of USD forks is an additional benefit. Unsprung weight is the term used to describe the weight of the motorcycle's parts, such as the wheels, brakes, and swingarm, which are not supported by the suspension. USD forks lower the unsprung weight by placing the heavier portion of the fork towards the bottom, which enhances suspension performance and improves handling.

Better Positioning of the Brake Caliper

Another benefit is the superior installation position for brake calipers that upside-down forks provide. The caliper is positioned on the underside of the fork leg, which directs the braking effort on the stiffer slider rather than the more flexible stanchion. This results in better brake performance, particularly during hard braking.

Reduced Friction

Additionally, USD forks have less friction between the slider and stanchion. In conventional telescopic forks, friction caused by the stanchion sliding inside the slider can impair suspension performance. With USD forks, the slider moving within the stanchion achieves less friction and better suspension performance.

Conclusion

Summing up, USD forks are superior to conventional telescopic forks in many ways, including higher stiffness, less unsprung weight, improved brake caliper location, and decreased friction.

While it is a little heavy on your wallet, the advantages of USD forks make them the best option for high-performance bikes.
