2006 Cobra CX50 King Dirt Bike Torque Specs
Shop parts for a 2006 Cobra CX50 King Dirt Bike.
The 2006 Cobra CX50 King delivers the premium 50cc competition package in its fourth year with updated bodywork and revised suspension calibration. The air-cooled 50cc two-stroke with factory-tuned engine and premium chassis specification continues serving the fastest young 50cc competitors. Updated bodywork on the 2006 King improves aerodynamics and rider ergonomics for the more aggressive riding position competitive 50cc racers use during moto starts and high-speed sections. Subframe bolt torque at 10 Nm anchors the updated bodywork mounting system — post-break-in verification ensures the new panels are seated firmly against chassis mounting points.
