Welcome to the world of    motorcycle clutches!

As a leading power sports dealership, L&D Race Tech is dedicated to providing valuable insights and information to motorcycle enthusiasts. In this comprehensive guide, we'll explore the inner workings of a motorcycle's clutch system in precise detail, helping you better understand its importance and how it affects your ride.


The Clutch: A Brief Overview


 

The clutch is a vital component of a motorcycle's transmission system, connecting and disconnecting the engine's power to the rear wheel. By managing power delivery, the clutch allows you to smoothly start your motorcycle, shift gears, and maintain control while riding.

The Main Components


A motorcycle clutch consists of several key components, including:

  1. Clutch Lever: This hand-operated lever is mounted on the left handlebar and is connected to the clutch cable. Squeezing the lever disengages the clutch, while releasing it engages the clutch.
  2. Clutch Cable: The cable connects the clutch lever to the clutch mechanism inside the engine, transmitting the rider's input.
  3. Clutch Mechanism: Housed within the engine, this mechanism is responsible for the actual engagement and disengagement of the clutch. It consists of friction plates, steel plates, and springs.
  4. Friction Plates: These plates are covered in a high-friction material, allowing them to grip the steel plates when the clutch is engaged.
  5. Steel Plates: These metal plates are sandwiched between the friction plates, transferring the engine's torque to the transmission.
  6. Springs: The springs apply pressure on the plates, keeping them engaged when the clutch lever is released.

Wet Clutch vs. Dry Clutch


Motorcycle clutches can be categorized into two main types: wet and dry clutches.

Wet Clutch: A wet clutch is submerged in engine oil, which lubricates and cools the clutch components. This type of clutch is common in most motorcycles, as it offers a smoother engagement, less wear and tear, and reduced noise.

Dry Clutch: A dry clutch operates without oil, relying on air for cooling. This type of clutch is less common and mostly found in high-performance motorcycles. It offers a more direct feel and faster gear changes, but can be noisier and less durable than a wet clutch.

How the Clutch Works


When you squeeze the clutch lever, you're pulling the clutch cable, which in turn pulls on the clutch mechanism inside the engine. This action compresses the springs, releasing the pressure on the friction and steel plates. As the plates separate, they no longer transfer power from the engine to the transmission, allowing you to shift gears or come to a stop.

When you release the clutch lever, the springs push the plates back together, creating friction between the friction and steel plates. This friction allows the engine's power to be transferred to the transmission and, ultimately, the rear wheel.
