·         New 4Gx clutch assembly offers a stronger shoe design and improved reliability. 

·         Cobra exclusive 30mm USD forks feature a full cartridge design that is sized properly for the little racer.

·         Works-style hand-made oversized radiator featuring improved strength and cooling.

·         Cobra's "Mag" wheels are lighter weight and stronger than spoked wheels, and as always, maintenance-free! 

·         The CX50JR comes equipped with top of the line billet triple clamps that offer adjustable bar mounts so the bike can grow with your rider.

·         Improved silencer for more torque and less sound output.  

CX50 JR History

The Cobra CX50JR’s record remains firmly in tact…With Ryder DiFrancesco’s win in 2012 (the only five-year-old to ever win the title) the Loretta Lynn’s championship run for this little machine was extended to 17 straight years. Cobra has refined its littlest racer for 2013, making it more reliable, better suspended, and easier to ride.
