An automatic motorbike is very practical to use and can provide comfort for the rider. In addition, the automatic motorbike is very suitable for use in busy road conditions and hot weather.
Even with the comfort and convenience offered, this automatic motorbike requires more maintenance compared to other types of motorbikes. One of the components of the automatic motorbike that is known to be complicated is the CVT. This component requires intense maintenance to keep the automatic motorbike in top condition.
CVT is an important component in automatic motorbikes that differentiate them from other types of motorbikes. This component is not owned by other types of motorbikes. CVT stands for Continuously Variable Transmission which is a system for transmitting power from the engine speed to the motor wheels by relying on two pulleys (front and rear) connected to the V-Belt.
In order to properly care for an automatic motorbike, you need to first get to know the following CVT components for an automatic motorbike.
1. V-Belt

One of the important components in matic CVT is the V-belt. This component is an important component which is one of the wheel drives on the motor.
This V-belt is not only found on automatic motorbikes, but also in other types of motorbikes with the same function. However, on automatic motorbikes, the V-belt is a component that connects the front pulley and the rear pulley.
The V-Belt has a lifespan so it will break down eventually and need to be replaced. V-Belts usually have an expiration period ranging from 20,000 km to 30,000 km, but that depends on the way they are used.
2. Roller

The roller is one of the important components in the motor which functions as a front pulley drive and allows the belt to go up and down when the engine starts.
This component has a small round shape which makes it easier for the variator to move. So if this shape changes, in the sense that it is damaged or worn, it will cause damage when the motor is driven.
The way to find out the condition of the roller is to dismantle and lift the roller to check if it is damaged or not and needs to be replaced. The damage cannot be detected only when riding a motorbike, therefore you need to regularly check the condition of the motorbike.
3. Centrifugal Clutch

Centrifugal clutch or also known as clutch lining is generally found in automatic motorbikes because automatic motorbikes use a centrifugal type clutch.
This part differentiates it from other types of motorbikes because it uses a different type of clutch. The function of this clutch lining is to continue the rotation originating from the secondary axle to the wheels.
A mistake that is sometimes made by automatic motorbike riders is to use the gas and brakes at the same time so that it can damage this clutch lining component. So when you want to brake, turn down the gas speed to prevent damage to the clutch compass.
4. Fixed Primary Sheave

Fixed primary sheave is a component in the form of serrated sides that are connected permanently to the primary pulley shaft. This section itself serves as a place for the V-Belt to wrap around the pulley.
5. Sliding Primary Sheave

This component has something to do with the fixed primary sheave but this component is not attached permanently because it can shift left or right.
This component has a function to reduce or enlarge the diameter contained in the primary pulley. When this section moves closer to the fixed primary sheave, it will push the V-Belt loop and will make it wider.
6. Primary Shaft

The next component contained in matic CVT is the primary shaft. This primary shaft functions as a connecting medium for the crankshaft rotation. This section is connected directly to the crankshaft on a regular basis so that it is called the primary shaft.
7. Secondary Fixed Sheave

The next component is a secondary fixed sheave which is also called a secondary pulley. This section has two sides, namely the sliding sheave side and the fixed sheave side.
This component is connected to the secondary shaft. The function of this component is to adjust the size of the diameter contained in the secondary pulley.
8. Secondary Sliding Sheave

This component has the same function as the secondary fixed sheave, namely as a regulator of the size of a diameter contained in the secondary pulley.
The shape of the secondary sliding sheave is slightly thin when compared to the secondary fixed sheave. This shape is intended so that the movement of the secondary sliding sheave can affect the winding width of the V-Belt.
9. Secondary Sheave Spring

This component is usually shaped like a spiral which is usually placed on the primary pulley to regulate the movement of the primary sliding sheave.
Meanwhile, the secondary pulley will usually only use one per spiral to regulate the movement of the secondary sliding sheave. The correct position of this section will keep the sliding sheave tight.
10. Spacer

The spacer is shaped like a small metal tube that functions as a shaft on the inner wall of the pulley so that the shift of the inner pulley wall can take place smoothly without causing excessive friction.
11. Slider

The next component is the slider which serves to hold the inner wall so that it can move outward when it gets pushed from the roller.
12. Secondary Shaft

The secondary shaft is located on the secondary pulley which functions to transmit rotation from the secondary pulley to the double clutch (centrifugal).
13. Clutch Housing

This component is also called the clutch housing which functions to distribute the rotation of the V-Belt and receive rotation from the centrifugal clutch which is then forwarded to the rear wheel of the motor.
14. Cam Torque

This component plays an important role when the motorbike takes an uphill road. When traveling up an uphill road, the load on the rear wheel of the motorbike increases and the speed decreases.
This is because the motorbike requires a larger torque, for this is where the role of cam torque is to increase the torque. Cam torque will hold the driven pulley or secondary pulley from closing immediately so that the engine doesn’t drop.
15. Reduction Gear

The last component of the CVT is a reduction gear which functions to increase power and reduce the rotation speed made by the CVT.
The concept is with this reduction gear the rotational speed will be reduced but it will actually double the power produced. This power will be sent to the wheel axle. This gear is in the form of a helical gear that is tilted towards the shaft.
These are the components of matic CVT. By knowing the components of this CVT, if there is damage, it can be identified. Don’t forget to check and carry out routine motorbike maintenance.
