2023 CX50SRX KING

CX50 SRX // This bike earned the nickname King for a good reason!

Cobra’s flagship model in 1994 was the King 50. It changed motocross forever by introducing the first true race-ready 50cc motocross bike. Decades later, we’re still innovating, and in the time since, the King 50 has kicked off the careers of many of the world’s top racers including Davi Millsaps, Brock Tickle, Zach Osborne, Thomas Covington, Blake Baggett, Trey Canard, and Eli Tomac not to mention recent champions such as Adam Cianciarulo, Cooper Webb, Chase Sexton and Austin Forkner.

Local Races Won
  • Venom Series Engine  – This thing rips! Cobra engineers designed a ‘no-compromise’ torque curve featuring massive low-end torque for launching off the gate and out of corners, this in addition to Cobra’s classic over-rev that provides that ‘2nd gear’ for wide open situations. This little beast offers more power, more torque, less weight and a smaller, lighter package.
  • Forged and Anodized Aircraft-Grade Aluminum Wheels. Lighter and stronger featuring a spoke pattern designed to reduce unsprung weight and improve handling. 12” front and 10” rear.
  • Micro Handlebars – Cobra is proud to offer innovative Micro Handlebars across our 50cc lineup. These bars will revolutionize the way that young riders control their motorcycles by offering a reduced diameter grip area that inspires confidence and reduced fatigue.
  • Hybrid Oval Twin Spar/Backbone Frame with revised structure and removable aluminum subframe – reduces weight, improves handling, permits a twin radiator system, eases maintenance, and is stronger.
  • Twin Radiator System – Improves cooling, reduces power loss to heat, and increases ground clearance.
  • CARD Rear Shock has revised valving and reservoir design that tucks in tight creating a slim mid-section.
  • Quick-Change Air Filter with vertical orientation reduces the chance dirt encroachment into the engine.
  • Air boot/Air box provides a large volume of clean air between the filter and the carburetor resulting in more power everywhere.
  • Forged Aircraft Grade Aluminum Triple Clamps – These clamps are lighter, impart less force onto the fork tubes for improved suspension action, and they provide a clamping feature onto the steering stem for improved steering feel, and for 2023 the cushioned steering stops are improved.
  • Updated CARD Rear Brake System: Improved bore, piston, and seal improves responsiveness and longevity.
  • Optimized Ergonomics provide a slimmer, flatter seat for easier fore-aft transitions and accommodation for a larger range of rider size.
  • 5Gx Freewheeling Clutch – Precision engagement, durable, freewheels for increased corner speed and easier starting.
  • Revolutionary MXT “Smart Leg” Front Fork – Cobra’s exclusive 32mm USD CARD fork is the finest fork in minicycle racing! The Smart architecture simultaneously provides supple action over small bumps, and progressive control through the biggest of hits…A feature especially important for minicycles that run on tracks torn up by bikes twice their size! This fork features fully adjustable rebound and compression damping and bottoming control adjustment not found on any other fork of any size!
  • Works-Style Tuned Pipe for increased power and a flatter torque curve. The result: earlier clutch engagement for improved rideability and more over-rev for enhanced top speed.
  • Ergonomic Hand Holds that make lifting the bike easier both at the starting gate and onto the stand.
  • Updated Chassis Geometry: Longer wheelbase for improved stability. Shorter swingarm for reduced rear-end kick over braking bumps. Increased rake provides both improved stability and smoother cornering. Lengthened head tube stiffens front end for enhanced steering feel.
  • Dunlop Geomax MX33 Intermediate-Terrain Tires – A high-end bike deserves high-end tires. The 2023 King is outfitted with Dunlop Geomax MX33s front and back. Enhanced grip, improved slide control, and a larger contact patch with the ground all add up to reduced lap times. No corners cut here!
  • Spectro-Factory Fill – Cobra and Sprectro, two proud American companies with a long history in motocross, have teamed up to ensure that each Cobra model comes with the finest in lubricants and chemicals. This includes everything from wheel bearing grease, to brake fluid, to suspension fluid, to the oil on the air filter.
