2018 Cobra CX50 P3 Highlights & Improvements

The littlest Cobra was ridden home to its first ever national championship in 2017…In fact, the P3s dominated the competition at Loretta Lynn’s Ranch this summer. Check out the improvements for 2018:

  • NEW!  CARD Front & Rear Brake Systems – The days of adapting bicycle brakes are over! All Cobra 50s now come equipped with purpose built and designed minicycle brakes that will help take performance to the next level. The all-new CARD front and rear brake systems have better feel, more stopping power, and are easier to maintain. Furthermore, the front brake comes standard with a break-away lever, and there is adjustability and a choice of levers to fit every size of hand!

  • NEW!  Lightweight Wheels – The evolution of our class-leading ‘mag’ wheels continues with reduced weight and all-new super lightweight and cool looking brake discs. To wrap up this awesome package, the engineering geeks at Cobra also replaced all steel wheel bearing spacers with hard anodized 7075-T6 aircraft aluminum units to save a few more grams of un-sprung and rotating mass. Lightweight, ZERO maintenance, and great looking. Lighter wheels mean less rotating and un-sprung mass, which translates into improved acceleration, handling, and flight control.

  • NEW!  Billet Triple Clamps with Adjustable Bar Mounts – Both little 50cc models receive an all-new top triple clamp this year for increased steering clearance and a roomier rider compartment. Works-level hardware on a junior scale bike!

  • NEW!  Dunlop Geomax MX3S Intermediate-Terrain Tires – The 3S has proven itself to be the ultimate minicycle tire over the past few years, so of course Cobra will offer it as standard equipment. No corners cut here!

  • Venom Series Engine  – The P3 is also powered by Cobra’s Venom Series 50cc powerplant. This thing rips! Cobra engineers designed a  ‘no-compromise’ torque curve featuring massive amounts of 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.

  • Micro Handle Bars – Cobra is proud to offer Pro-Taper’s 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.

  • Bel-Ray Factory Fill – Cobra and Bel-Ray, two proud American companies with a long history in motocross, have teamed up to ensure that each Cobra model comes from the factory 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.

  • 5Gx Freewheeling Clutch – Precision engagement, durable, freewheels for increased corner speed and easier starting.

      • Longer driveline life (crank, transmission, clutch, chain) and improved drive through rough choppy terrain

  • Progressive Rate Rear Suspension

    • Linear rising rate without a link! Reduced weight, and friction

      • Supple over small bumps for good traction…Absorbs big hits for aggressive riding.
