Hybrid Oval twin spar/Backbone frame: This new chassis reduces weight, improves handling, allows the radiator to be tucked in, eases maintenance, and is stronger.

The precision design of the swingarm ensures optimal suspension performance, allowing riders to navigate through rough terrains with confidence. With its combination of strength, stability, and suspension efficiency, the swingarm of the CX50JR provides a solid foundation for riders to push their limits and conquer any motocross challenge.

The CX50JR is equipped with high-quality Cobra 10″ Forged & Anodized front wheels and Cobra 10″ Forged & Anodized rear wheels. These wheels provide excellent strength and durability. Wheel Front / Rear: Cobra 10″ Forged & Anodized/ Cobra 10″ Forged & Anodized.

A high-end bike deserves high-end tires. The 2025 CX50JR will be outfitted with Dunlop Geomax MX34 Intermediate-Terrain Tires 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!

Revolutionary MXT “Smart Leg” Front Fork: Cobra’s exclusive 32mm USD CARD fork is designed to be the finest fork in minicycle racing! Cobra’s innovative design 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, and is built on a spring cartridge architecture that’s ready to tackle the toughest terrain right out of the crate.

CARD rear shock features high and low speed compression adjustment. The shock tucks in tightly for a slim mid-section providing outstanding performance and control.

The front brake features a breakaway low-friction ergonomic lever designed to give rather than break during a tip-over.

Cobra is proud to offer Micro Handlebars on the 2025 CX50JR. These bars have revolutionized the way that young riders control their motorcycles by offering a reduced diameter grip area that inspires confidence and reduced fatigue. The bars are mounted to Forged Aircraft Grade Aluminium Triple Clamps with integrated mount. These clamps are lightweight, impart low clamping forces into the fork tubes for improved suspension action, and they provide a clamping feature onto the steering stem for improved steering feel.

ll-New Ergonomics provide a slimmer, flatter seat for easier fore-aft transitions and accommodation for a larger range of rider size. All this while maintaining the most suspension travel in its class.
