2005 Cobra CX50 King Dirt Bike Torque Specs
Shop parts for a 2005 Cobra CX50 King Dirt Bike.
The 2005 Cobra CX50 King delivers the premium 50cc competition package in its third year with updated suspension components and improved chassis hardware. The air-cooled 50cc two-stroke with King-specification engine tuning and premium suspension hardware serves the most experienced and fastest young riders in the 50cc class. Three years of King-specific development refine the premium specification based on competitive feedback from the top of the 50cc class. The swingarm pivot bolt at 22 Nm and shock mount hardware at 18 Nm reflect the increased chassis loads these faster, heavier-handed competitors generate compared to entry-level 50cc riders.
