2005 Cobra CM50 Dirt Bike Torque Specs
Shop parts for a 2005 Cobra CM50 Dirt Bike.
The 2005 Cobra CM50 is the final year of the original competition 50cc motocross platform. The air-cooled 50cc two-stroke single closes out a twelve-year production run as one of the most enduring American-made youth motocross machines. The 2005 CM50 benefits from the most refined version of every specification developed over that long production history. Riders and families maintaining the 2005 model are caring for a machine with a distinct legacy; precise torque application protects the aluminum hardware that no longer has a new-production parts supply behind it.

Final-Production Notes
Premix two-stroke — no oil drain plug. The final CM50 deserves the same careful torque practice as the first. A 1/4-inch drive click-type wrench — 2–25 Nm — protects aluminum threads on a machine whose parts are finite.
Thread Locker Application
- Rear sprocket nuts
- Disc bolts
- Subframe bolts
- Exhaust flange nuts
Torque Wrench Selection
A 1/4-inch drive click-type — 2–25 Nm — is the right tool for every fastener on the final CM50. Twelve years of American motocross heritage deserves calibrated maintenance.
