Bike Parts And Components


The frame of the bike is most commonly made from an aluminium and steel alloy. The design focuses on the suspension of the rear wheel. Custom frames can be made from materials such as magnesium, carbon fibre and titanium. However, these can be prohibitively expensive.




Bikes tend to have a suspension arrangement that connects the two wheels to the chassis. However, chopper types have a more rigid frame and only need suspension for the front wheel. Suspension is one of the most important parts of the bike. If this breaks down it can render the vehicle immobile.

The suspension system of a bike works much the same way as that of a car. The front suspension is built onto a front fork. This will usually be made from a series of telescoping tubes. Rear suspension is attached to a swing arm through bolts which also hold up the axle of the wheel. Dual shocks are usually in place to support the rear suspension.

Wheels And Tyres

Steel and aluminium are the most commonly used metals for constructing wheel rims. Cast disks made from magnesium alloys are also prevalent on modern bike wheel designs. Earlier models had separately built wire wheels. New technology has now given rise to high end, carbon fibre versions.

Most motorcycles have pneumatic tyres in place. These come in an abundance of possible configurations. The tyres of dirtbikes have deep treads to increase grip. Touring bike tyres on the other hand are made from thicker rubber so that they can be rode for longer.


Most bikes have two brakes. They control the front and the back wheel respectively. However, a number of models have a single control for both brakes. These are known as “linked brakes”. Modern ones are significantly more powerful.

Front brakes are designed to have more effective stopping power than the back. This is a consequence of weight transfer and the size of the wheels. Brakes tend to be based on drums or disks.

In recent years anti lock braking systems have been developed. This technology is now the standard in the motorcycle manufacturing industry. They tend to be found on bikes that are 500 cc or higher.


A standard motorbike will typically have an instrument panel. This is at the front of the bike within sight of the rider. This panel will contain the speedometer, tachometer and odometer. Fuel gauges inform the rider of how empty or full the petrol container is.

As the name suggests, the speedometer will record the riders speed. It is a legal requirement for all road worthy vehicles to have this instrument. It allows the rider to stay within the speed limit. It is also useful for calculating the approximate length of a journey.

The odometer will display how far the bike has travelled. Looking at this instrument will help buyers determine how old a used motorcycle is. This can also affect the price of it. The tachometer displays the revolutions per minute of the shaft or disk within the bike.
