NEW!  Titanium Edition! – Cobra is bringing works level goodies to the minicycle market this year! For 2019 we’ve included a super strong and lightweight Ti rear axle and swingarm pivot. Additionally, we’ve included all aluminum fastening hardware to the mix. Lightweight! Looks great!

NEW!  Forged Aircraft Grade Aluminum 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 Aluminum 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.

IMPROVED!  Coated Exhaust Pipe – New ceramic coating looks better and cleans up easier.

‘War Head’ Cylinder – Once again, the CX50 Factory Works Edition maintains its place at the bleeding edge of 50cc racing technology. Cylinder porting has been updated for 2018 to improve power and torque throughout the RPM range. What results is a broad torque curve that provides sooner and smoother clutch engagement for better starts, improved throttle control, and faster acceleration.

Extended Wheelbase – The 2019 FWE comes equipped with an extended swingarm for those deep and rough tracks that will benefit from added stability. Adjustability is built in for short, tight tracks as well.

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.

Revolutionary MXT “Smart Leg” Front Fork – Cobra’s exclusive 32mm USD CARD fork is designed to be 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.
