Pulsar 135 motorcycle crankshaft

Types of Pulsar 135 motorcycle crankshafts

A Pulsar 135 motorcycle crankshaft is the vital component that converts the linear motion of the pistons into rotational motion, which helps power the motorcycle. It is available in the following types.

• Single-cylinder crankshaft

Single-cylinder crankshafts are commonly used for motorcycles with single-cylinder engines. They are compact and lighter, making them suitable for low-capacity motorcycles. It connects the piston to the transmission gears and controls the power of the engine.

• Split-single crankshaft

The Split-single crankshaft is utilized in motorcycles with split-single engines. It's an unusual design where the motor has two cylinders that share a solitary chamber. This kind of crankshaft is more complicated, and it requires exact assembling to guarantee the two cylinders share a typical chamber.

• Parallel-twin crankshaft

The parallel-twin crankshaft is ordinarily utilized in motorcycles with parallel-twin engines. This design includes two cylinders adjusted opposite to each other. The crankshaft is heavier and more massive than the single-cylinder crankshaft. The parallel-twin crankshaft gives better equilibrium and smoother activity because of the 360-degree wrench point. This implies the cylinders move up all the while, bringing about less vibration.

• Flat-twin crankshaft

The flat-twin crankshaft is utilized in motorcycles with flat-twin engines. This design includes two horizontal cylinders that are inverse to one another. The crankshaft is more extensive than the parallel-twin crankshaft because of the level course of action of the cylinders.

• Triple-cylinder crankshaft

The triple-cylinder crankshaft is utilized for cutting-edge motorcycles with triple-cylinder engines. This design includes three cylinders adjusted 120 degrees from one another. The triple-cylinder crankshaft is heavier and more massive than the single-cylinder crankshaft. This design gives smooth power conveyance and a more extensive force band because of the three cylinders.

• Offset-crankshaft

Offset-crankshaft is a high-level crankshaft design that is utilized in superior motorcycles. This design includes the crankpins being balanced from the wrench pivot. This makes the cylinder development and timing not quite the same as a standard crankshaft. The offset-crankshaft design is intended to improve motor effectiveness, force yield, and reaction.

For the maintenance of the Pulsar 135 motorcycle crankshaft, owners should make sure to use the specified oil for the engine. Also, keep the engine oil clean and dirt-free. It aids the lubrication of all moving parts of the engine. The oil filter should be replaced at every oil change. The oil filter helps to keep the engine oil free from dirt and debris. The air filter should be checked and replaced. It aids the engine to breathe clean air. The spark plugs should be checked and replaced as at when due. The spark plug provides the needed spark for the engine to run. The valve clearance should be checked and adjusted. The cooling system for the engine should be checked for leaks and the coolant replaced after the specified time. The electrical connections should be checked and cleaned to avoid electrical issues. The battery should be checked and replaced as at when due. The brakes should be checked and replaced if worn out. The tires should be checked for cuts or bulges and replaced when necessary. The chain and sprocket should be cleaned and lubricated regularly.

How to choose Pulsar 135 motorcycle crankshaft

• Engine Characteristics

When choosing a crankshaft, consider the features of the motorbike. Understand the engine's displacement, stroke length, connecting rod ratio, and the overall goal of the engine build. The crankshaft is considered to be the backbone of the engine, so choosing the correct crankshaft is critical for the engine's performance and reliability. It connects the piston to the flywheel and transforms the linear motion of the pistons into rotational motion. The crankshaft's design is determined by the engine's displacement, stroke length, and connecting rod ratio.

• Displacement

The engine displacement is the volume of the cylinders inside the engine. The larger the displacement, the more power the engine can produce. A large displacement engine is suitable for riding on highways or carrying heavy loads. A smaller displacement engine, like the pulsar 135 crankshaft price, is better for commuting and daily use.

• Stroke Length

Stroke length is the distance the piston travels inside the cylinder. This, combined with the engine's displacement, determines the power and torque of the engine. A longer stroke length will produce more torque at lower RPMs but limits the engine's ability to rev high. A shorter stroke length allows the engine to rev higher but sacrifices low-end power.

• Connecting Rod Ratio

The connecting rod ratio is the length of the connecting rod compared to the stroke length of the crankshaft. A higher connecting rod ratio allows the piston to travel a longer distance and produce more torque. In general, a higher connecting rod ratio is good for low-end power and acceleration.

• Build Goal

Understand the goal of the engine build. Is the goal to increase horsepower and top speed or to improve low-end torque and acceleration? Choose a crankshaft that matches the goal of the engine build. For example, a crankshaft with a longer stroke length is suitable for improving low-end torque and acceleration but may sacrifice top speed.
