2013 Cobra CX65 Dirt Bike Torque Specs
Shop parts for a 2013 Cobra CX65 Dirt Bike.
The 2013 Cobra CX65 continues the liquid-cooled 65cc youth motocross platform in its seventh year with updated bodywork and revised ergonomic specifications. Updated bodywork on the 2013 CX65 improves the riding position for the typical 65cc class competitor — the ergonomics of this class span a wide range of rider ages and sizes, from the lightest riders who have just stepped up from 50cc to the largest riders approaching the 85cc class age limit. Updated ergonomics affect subframe loading; verify subframe bolt torque at 15 Nm after the first few rides as the new body panels settle into their chassis mounting positions.
