-2021 Cobra CX50P3 and CX50JR -
Highlights & Improvements
NEW! Steering stop design with built-in cushion.
NEW! Forged and anodized wheels made of aircraft-grade Aluminum. These wheels are lighter and stronger featuring an all-new spoke pattern resulting in reduced unsprung weight and improved handling. 10” front and 10” rear.
NEW! Mega Flo Yellow Plastic.
Venom Series Engine – Both the P3 and JR are 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.
Spectro-Factory Fill – Cobra and Spectro, 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.
Forged Aircraft-Grade Aluminum Triple Clamps – All of our 50cc models receive new clamps in 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.
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.
Dunlop Geomax MX33 Intermediate-Terrain Tires – Dunlop is at it again. In 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.
Coil Mounting – The ignition coil is now moved further away from the engine to keep the critical electronic components cooler.
IMPROVED Air Box – A reshaped airbox opening allows easier installation of the air filter.
Lightweight Fasteners – Several fasteners have been re-engineered from aircraft grade 7075-T6 Aluminium for even more weight savings.
