Long live the King! Cobra's CX50SR is all new for 2010... Like it's big brother, the King receives a twin-spar chassis and all-new bodywork for 2010. 90% of the field at Loretta Lynn's AMA national championships can't be wrong!

Bike History

The heritage of the 'King 50' is simply unmatched. From Davi Millsaps' back-to-back championships in the mid-1990s, to filling the top twenty-four places at this year's AMA national championships, to sweeping the podium at the 2009 MX Master Kids in Belgium, no other 50cc racing motorcycle offers this level of proven performance. To top it off, Cobra is not resting on its laurels for 2010. Enter the completely redesigned 2010 King 50. All new twin-spar chassis.. All new super slick ergonomics.. All new eye-popping looks. Cobra has raised the bar once again with the motorcycle that pros like Millsaps, Izzy, Canard, Stroupe, and Bowers credit with creating the 'Cobra Generation'. Let’s take a closer look.

1) For years, Cobra has been way ahead of the competition with its 30mm USD cartridge fork. Cobra has made the same technology that is on full size bike available to the little guys and girls. The result: more control, smoother ride over rough track surfaces, and improved chassis stability.

2) Mag wheels are as tough as they come.. no spokes to worry about and they're lighter!

3) 50cc powerplant is the best in the business.. split-port exhaust, tuned pipe, real air filter and air box that doesn't allow dirt to drop in and get entrained into the engine, and to top it off, Cobra's 3-G (3rd generation) clutch that is both reliable and hooks up better than any of its competitors. For 2010, the King 50 engine receives a bigger airbox and new pipe for more power and torque, and the angle of the inlet has been straightened out to help the carburetor jet more cleanly and to give airflow a straighter shot into the cylinder. The result? More controlled power for better starts and lower lap times!

4) The all-new oval tube High Strength Low Alloy twin spar frame for 2010 is a smaller version of its big brother found on the CX65. This architecture is laterally very stiff, but allows for the right amount of torsional flex so the bike behaves well over bumps and flows through rutted corners at the same time.

5) For over a decade, the King 50 has exhibited a boxy look that loved by some and tolerated by most. The 2010 King 50's new bodywork is radically updated and modernized. Most importantly, it shares many ergonomic features with its big brother, the CX65, so that transitioning back and forth between both bikes will be seamless.

6) As expected, the rear suspension is best in class as well. The Fox Podium X shock is adjustable both in compression and rebound, and it has a nitrogen charged piggy back reservoir to maintain consistent performance throughout the entire length of a moto.

7) Top all that off with quality Scott grips and Dunlop tires, and you have an unbeatable package!
