2017 Cobra CX50FWE Dirt Bike Torque Specs
Shop parts for a 2017 Cobra CX50FWE Dirt Bike.
The 2017 Cobra CX50FWE Factory Works Edition refines the premium 50cc competition package with updated suspension settings and improved component specifications. The air-cooled 50cc two-stroke with Factory Works suspension, chassis geometry, and braking hardware serves top-level youth competition. Updated suspension damping on the 2017 FWE improves handling consistency across different track surfaces — an important advantage in the 50cc class where chassis confidence directly affects the young rider’s ability to focus on race craft rather than machine behavior. Precise fork clamp torque at 8 Nm maintains the updated suspension’s geometry exactly as designed.
