MC 300

The 2025 GasGas MC 300 brings the raw thrill of two-stroke motocross into a refined, modern package. Its responsive power delivery and feather-light handling make it equally suited to aggressive racing and spirited weekend riding. With a strong, torquey engine and agile chassis dynamics, it delivers both blistering performance and easy manoeuvrability, helping riders tackle technical sections with confidence. Every aspect has been crafted to strike the perfect balance between race-ready capability and all-day riding enjoyment, making it a stand-out choice for those who value both speed and control.​​

 Refined Powertrain & Control At the core of the MC 300 is a punchy two-stroke engine with advanced throttle-body fuel injection, providing sharp, predictable throttle response across the rev range. Its power is smooth yet forceful, with a broad mid-range that excels in a variety of track conditions. The electronic exhaust control system further refines delivery, ensuring optimal performance whether you are carving through loamy berms or powering across hard-packed straights. Riders benefit from a machine that can be tailored to their preferred style, offering both an approachable, forgiving nature and the ability to deliver serious race pace.
Chassis Enhancements for Sharp Handling A carefully re-engineered chassis gives the MC 300 its sharp, precise handling characteristics. Weight has been trimmed in key areas to improve responsiveness, particularly around the upper shock mount and steering head, making the bike more agile without sacrificing stability. Revised engine mounts contribute to improved chassis flex, offering a planted yet nimble feel through turns. These refinements allow the bike to change direction effortlessly while maintaining traction and control, giving riders the confidence to push harder and ride longer with less fatigue.
Premium Suspension & Race-Ready Components Equipped with high-performance WP XACT suspension, the MC 300 delivers exceptional control and comfort over rough terrain. The 48 mm air forks provide easy adjustability for fine-tuning to track conditions, while the rear shock offers consistent damping performance over long motos. A lightweight swingarm, precision braking system, and race-grade wheels complete the package, ensuring the bike is as durable as it is fast. These premium components work in harmony with the chassis to give the rider a responsive, stable, and exhilarating experience from the first lap to the chequered flag.
