Clutch

A component that connects engine power to the drivetrain as engine RPM increases, allowing the engine to idle without driving the kart

Clutch Drum

The outer rotating portion of the clutch that engages the drivetrain and transfers engine power to the chain

Clutch Shoes

Friction components inside the clutch that move outward as RPM increases and engage the clutch drum

Jackshaft

A rotating shaft in the drivetrain that transfers engine power to the rear axle and accommodates drivetrain components such as sprockets and the clutch

Chain

A series of linked metal rollers that transfers rotational power from a drive sprocket to a driven sprocket

Drive Sprocket

The sprocket connected to the engine or jackshaft that transfers power into the chain

Driven Sprocket

The sprocket connected to the axle or jackshaft that receives power from the chain

Sprocket

A toothed wheel that engages with a chain to transfer rotational power

Gear Ratio

The relationship between the number of teeth on the driven sprocket and the number of teeth on the drive sprocket that affects acceleration and top speed

Chain Tension

The amount of tightness in the chain

Chain Breaker

A tool used to remove pins from a chain so the chain can be shortened, lengthened, or replaced

Chain Guard
