2016 Cobra CX50JR Dirt Bike Torque Specs
Shop parts for a 2016 Cobra CX50JR Dirt Bike.
The 2016 Cobra CX50JR continues the Junior motocross platform into its eleventh year with updated suspension calibration and improved component quality. The air-cooled 50cc two-stroke in the youth-specific competition chassis serves the youngest class of motocross competitors with a well-proven machine. Updated suspension damping on the 2016 JR provides more consistent handling at the current speeds young competitors achieve in the Junior 50cc class — the class has evolved alongside the machines that serve it, and the 2016 JR reflects that evolution with suspension calibration matched to current track surfaces and competition standards.
