2009 Cobra CX65 Dirt Bike Torque Specs
Shop parts for a 2009 Cobra CX65 Dirt Bike.
The 2009 Cobra CX65 continues the liquid-cooled 65cc youth motocross platform in its third year with updated components and refined suspension calibration. The CX65 in its third year benefits from two full competitive seasons of real-world feedback. The young competitors who race the 65cc class at this point have specific, well-articulated demands for handling and power delivery that Cobra’s development program incorporates into the 2009 model. Linkage bolt torque at 25 Nm is a particularly important specification on the 65cc platform, where the progression riders who compete in the class generate more aggressive landing loads than the beginner riders in the classes below.

65cc Class Notes
Premix two-stroke — no oil drain plug. Linkage bolt torque at 25 Nm deserves particular attention given the more aggressive landing loads progression-class riders generate. Inspect coolant level and radiator hose clamps at each service. A 3/8-inch drive click-type handles the primary fastener range.
Thread Locker Recommendations
- Rear sprocket nuts
- Disc bolts (front and rear)
- Linkage bolts
- Subframe bolts
- Exhaust flange nuts
Torque Wrench Selection
A 3/8-inch drive click-type — 10–50 Nm — handles the primary fastener range. A 1/4-inch drive for water pump cover bolts. Third-year platform performance is delivered through consistent calibrated maintenance.
