COBRA CX50 JR 2023 CARACTÉRISTIQUES ET BÉNÉFICES
La fourche intelligente CARD
(Cobra Advanced Racing Development) 32mm totalement ajustable. Toute nouvelle, désignée exclusivement pour le 50cc (ce n'est pas une version écourtée d'un modèle plus gros). L'architecture intelligente donne à la fois souplesse dans les petites bosses et une maitrise progressive dans les grosses bosses (idéale sur track rought) cette fourche dispose également d'un ajustement sur la compression et le rebound, que l'on ne retrouve pas ailleurs et ce, toute fourche confondue.
Le CFD (cobra friction drive) BREVETÉ
AUCUNE compagnie n'a rien de semblable. Facile d'entretien, c'est lui qui encaisse les coups. Une transmission, une clutch, engrenage, chaine et sproket bien protégée plus une meilleure traction dans toute sorte de terrain.
L'embrayage 5th génération
Reçoit un procédé de fabrication raffiné qui facilite chaque contact entre le basket et les shoes pour donner une accélération précise et rapide. Meilleur curculation de l'huile pour la 5eme génération.
De plus, Cobra a mis beaucoup d'énergie sur le développement d'une clutch facile d'entretien et fiable.
Le tout nouveau carburateur EASY RESTART
Facilite le redémarrage après une chute, ce qui fait la différence entre perdre une position ou perdre une course.
L'amortisseur PIGGYBACK
Ajustable sur rebond, compression et vitesse.
- Les wide pegs 50mm;
- La plus grosse airbox du marché avec un vrai filtre à air;
- Sans compter les mags, faciles d'entretiens et INDESTRUCTIBLES.
Bref, rien n'est comparable au contrôle d'un Cobra. Et n'oubliez pas que sans contrôle, la puissance n'est rien...

- 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. 10” front and 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.
- 5Gx Freewheeling Clutch – Precision engagement, durable, freewheels for increased corner speed and easier starting.
- 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.
- 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.
- 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.
- Updated CARD Rear Brake System: Improved bore, piston, and seal improves responsiveness and longevity.
- 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.
- Dunlop Geomax MX33 Intermediate-Terrain Tires – A high-end bike deserves high-end tires. The 2023 JR and P3 are 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.
