Types of Clutch

Regular Clutch:


The clutch component in an engine is used to control or manage the transfer of power / energy from the main engine to the gearbox of the engine. Mainly the responsibility of the clutch assembly is to release the power / control of the engine over the bike. It acts as an agent over the bike to shift between different gears. Shifting gears without pressing the clutch would result in breakdown of the complete engine and may result in an accident. Transition during shifting gears is smoothly accomplished with the use of clutch.


Slipper Clutch:


Slipper clutch which is also known as "back torque limiter clutch", "Assist clutch" or "slip and grip clutch" is used to smoothen or reduce the effort required to release the clutch lever while decelerating from a higher speed while riding a bike. Slipper clutches comes in handy when it's necessary to shift 2 to 3 gears within a short period of time may be during sharp turns or any scenario which requires heavy deceleration or braking. The Slipper clutch allows the clutch to partially slip until the engine speed matches the bike speed.


Different types of drives for bikes

Chain Drive:


Chain drive bikes usually have two sprockets and a chain which allows the power of the engine to be transferred to the bike which causes movement. The two main types of chain are O ring and X ring. This type of drive system is cheap to manufacture, easy to implement and repair but makes more noise and requires regular maintenance. The chain drive is very efficient as it reduces the overall engine power by only 2 to 5 %. More power of the engine is lost if the Chain Drive Assembly is not lubricated or not well maintained. To be tested or replaced every 25000 km and maintenance to be done every 500 to 800 km.


Belt Drive:


This type of drive is similar to the chain drive where the sprockets are replaced by pulleys and the chain is replaced by a rubber belt. Belt drive is usually deployed on larger bikes making the ride smooth with less noise due to its rubber construction. They are prone to stretching or slippage and causes a power loss of around 11 % due to sudden burst of power. The replacement and repairs is very difficult in the case of the belt drive. If maintained properly this drive system can last for 90000 km.


Shaft Drive:


Slipper clutch which is also known as "back torque limiter clutch", "Assist clutch" or "slip and grip clutch" is used to smoothen or reduce the effort required to release the clutch lever while decelerating from a higher speed while riding a bike. Slipper clutches comes in handy when it's necessary to shift 2 to 3 gears within a short period of time may be during sharp turns or any scenario which requires heavy deceleration or braking. The Slipper clutch allows the clutch to partially slip until the engine speed matches the bike speed.


Type of Engines:


  • Single - single-cylinder engines have the cylinder vertical, inclined or horizontal;
  • Parallel-twin - two-cylinder engine which has its cylinders arranged side by side;
  • Inline-three - three-cylinder engines, normally mounted transversely;
  • Inline-four - four-cylinder engines, normally mounted transversely;
  • V-twin (trans) - two-cylinder engine in a transverse position arranged in a V configuration with angles less than 90°;
  • V-twin (long) - two-cylinder engine mounted longitudinally arranged in a V configuration;
  • V4 - four-cylinder engine arranged in a V configuration;
  • Flat-twin (aka boxer) - two cylinder engine horizontally opposed;
  • L-twin - two-cylinder engine in a transverse position arranged in a V configuration with angles of 90°;


Type of Tyres:


  • Sport: Offer high grip for cornering but typically wear out before 1K miles.
  • Sport Touring: Great for riding long distances, especially a lot of straight roads.
  • Touring: Generally offer increased tread life, comfort, and all-season traction.
  • Scooter: made for a scooter
  • On/off road:think, super swampers and big lifted trucks but for motorcycles/ATVs
  • Dual-Sport: Have knobby tread like off-road tires but the tread is wider. Can be used on and off pavement effectively.
  • Enduro: Tires made for sport that is predominantly off-road
  • Motocross: special road-racing tires with grooved tread to grip both the pavement and dirt
  • Racing: Also referred to as a slick. High performance tire that does not blister under high heat.
