Specifications of Jawa 42 FJ

Refers to the design and configuration of the engine. Most petrol bikes typically use either a single-cylinder, twin-cylinder, or occasionally a multi-cylinder (like a four-cylinder) engine.

Represents the highest rotational force output by the engine, usually measured in Newton-meters (Nm) or pound-feet (lb-ft). It indicates the engine's pulling power.

Indicates the total count of combustion cylinders in the engine. Common configurations include single-cylinder, twin-cylinder, and four-cylinder setups.

Describes the method used to dissipate heat from the engine. Petrol bikes often use air-cooling or liquid-cooling systems to maintain optimal operating temperatures.

Describes how the engine is initiated. Most petrol bikes use electric starters, kick starters, or both, to commence engine operation.

Indicates the arrangement of gears that transmit power from the engine to the wheels, allowing the rider to adjust speed and torque.

These measurements describe the diameter (bore) and length (stroke) of the cylinder in the engine. They directly affect an engine's performance characteristics.

These measurements describe the diameter (bore) and length (stroke) of the cylinder in the engine. They directly affect an engine's performance characteristics.

Reflects the ratio of the maximum volume in the cylinder (when the piston is at the bottom) to the minimum volume (when the piston is at the top) during the engine cycle. Higher compression ratios generally lead to more efficient combustion.

Specifies the level of emissions produced by the bike, conforming to regulatory standards. Petrol bikes typically adhere to norms like Euro or BS (Bharat Stage) emissions standards.

Provides a designated area for the pillion passenger to rest their feet comfortably during rides.

Provides a designated area for the pillion passenger to rest their feet comfortably during rides.

Indicates the distance from the ground to the top surface of the bike's seat, influencing rider comfort and accessibility, especially for shorter or taller individuals.

Refers to the diameter of the disc or drum used for the front brake system on a petrol bike, influencing braking performance and heat dissipation.

Indicates the diameter of the disc or drum used for the rear brake system, contributing to the bike's overall braking effectiveness and control.

Describes the configuration of the drivetrain, such as front-wheel drive, rear-wheel drive, or all-wheel drive, affecting traction and handling characteristics.
