Motorcycle suspensions have significantly less geometries to think about than cars as they are having two wheels. However different geometries may have big effects in the bike’s handling. Here the geometries are divided into front and rear geometries.
Following are the in-depth details of a motorcycle suspension system and the important aspects relating it
The most variations and working of the most popular and in use front suspension in motorcycles are as follows –
Telescopic fork suspension is the most common and conventional type of front suspension and is used in almost every type of motorcycle today. It consists of a hydraulic tube with an internal spring coil. One of its ends has two forks attached to the steering of your motorcycle, while the other attaches to the front wheel spindle. The end attached to the steering has T-clamps connecting the two parts
The main advantages of telescopic fork suspensions is that it has
In USD the bottom part of the conventional telescopic fork are connected to the steering and are generally seen in the sports category. The USD arrangement decreases the total unsprung weight of the motorcycle along with increasing torsional stiffness which improves handling. The main disadvantage of this arrangement is that they may lose all the damping oil suddenly as they are inverted making the system impossible to work.
Saxon – motodd suspension system has a wishbone that mounts to the frame of the motorcycle and supports the monoshock unit which reduces the braking and suspension forces on the telescopic forks. The wishbone has a shock absorber that increases the stability and offers better balance during the brake drive as the trail and caster angle increases instead of decreasing during braking.
Some other types of front suspension variants are Hossack/Fior (Duolever) and Hub-centered Steering
Plunger suspension is a quite sophisticated design in which the vertical travel of the rear axle was controlled by plungers suspended by springs.
This design had three main disadvantages-
2. Swing Arm
It is a single-sided or double sided mechanical mechanism which connects rear wheel to the body and is the main component of the rear suspension in almost all modern bikes and ATV’s. Some manufacturers use swingarm in front suspensions of the scooters and motorcycles as it simplifies the maintenance.
Types of swingarms-
Hence the manufacturers employ this type of suspension on some of the high-performance bikes. In conclusion, this type of bike suspension provides better torsional strength and stability to the motorcycle.
As the name suggests, it refers to two shock absorbers at the rear end of a motorcycle. these gave a benefit of increased rear wheel travel due to which they were highly accepted. The advantages of twin shock absorbers are:
This suspension system includes a single shock absorber positioned near the center of bike’s chassis. It’s one end is attached to chassis and the other end the swing arm which is attached to the rear wheel. This enables longer stroke for the shock absorber which results in longer travel of the rear wheel. Since it is located closer to the bike’s center, therefore it increases the handling and agility of bike
