2019 Cobra CX50 SR Highlights & Improvements

NEW! Forged Aircraft Grade Aluminium Triple Clamps – All of our 50cc models receive new clamps for 2019. 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.

NEW! Frame Head Tube and Steering Stem – A thinner wall head tube and a 7075-T6 Aluminium steering stem work together to reduce weight and centralize mass.

NEW! Dunlop Geomax MX33 Intermediate-Terrain Tires – Dunlop is at it again. For 2019 they have introduced the completely re-engineered Geomax MX33. Enhanced grip, improved slide control, and a larger contact patch with the ground all add up to reduced lap times. No corners cut here!

IMPROVED! Front Brakes – Further refinements on the CARD front brake system include a more powerful 9.5mm master cylinder piston, improved master cylinder bore finish for better brake feel, and a thinner, more ergonomic brake lever to better fit small hands.

IMPROVED! Lightweight Fasteners – Several fasteners have been re-engineered from aircraft grade 7075-T6 Aluminium for even more weight savings.

Venom Series Engine – The 2019 King 50 is 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 line-up. 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.

Revolutionary MXT “Smart Leg” Front Fork – Cobra’s exclusive 32mm USD CARD cartridge 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 also features fully adjustable rebound and compression damping and bottoming control adjustment not found on any other fork of any size!

Class-leading Twin Spar High-Strength Low-Alloy Oval Tube Frame – Super-strong, outstanding lateral strength with just the right amount of torsional rigidity.

Off-plane Tuned Expansion Chamber – Packages tight, features D-shaped header for minimal flow losses.
