2021 Cobra CX50P3 Dirt Bike Torque Specs

Shop parts for a 2021 Cobra CX50P3 Dirt Bike.

The 2021 Cobra CX50P3 continues the three-speed automatic 50cc platform with updated suspension settings and improved component quality. The air-cooled 50cc two-stroke with automatic three-speed transmission serves its sixth generation of beginner youth riders, having returned to the lineup in 2016 after a decade-long absence. The three-speed automatic’s value proposition — reducing the learning burden on youngest riders — remains unchanged across all its production years. Updated suspension on the 2021 P3 improves the machine’s already beginner-friendly character with even more compliant response to the varied ground contacts beginner riders encounter as they learn.

Three-Speed Automatic Notes

Premix two-stroke — no oil drain plug. Updated suspension makes shock mount verification especially important. Transmission cover bolts at 8 Nm require periodic checks. A 1/4-inch drive wrench handles all fasteners.
