Equipped with a 300cc ZONGSHEN 4-stroke single-cylinder engine developing 26 hp at 8500 rpm, this adult 300cc motocross delivers crisp, manageable power designed for riders seeking solid performance without compromise. Air cooling ensures proven reliability even during the most intensive sessions, while the CDI ignition guarantees instant starting and smooth operation. Starting is done via kick-start or electric start according to your preference, and the PE30 carburetor, combined with its air filter and airbox, ensures a perfectly metered air-fuel mixture for consistent performance on every outing. At XtremRS, every engine component is selected for its robustness and longevity, and our customer service is by your side to answer all your technical questions regarding the motorization of your adult 300cc motocross.

Chassis: a reinforced tubular frame for an exceptional adult 300cc motocross

The chassis of this adult 300cc motocross relies on a reinforced tubular steel frame combined with a reinforced aluminum swingarm, offering remarkable rigidity and lightness that enhance every ride. With a length of 2120 mm and a wheelbase of 1440 mm, the adult 300cc motocross displays compact and manageable dimensions without sacrificing stability at high speeds. The 920 mm seat height allows for a natural and confident positioning for the rider, while the dry weight of 115 kg ensures uncompromising maneuverability on all types of terrain. The front (1.60X21") and rear (2.15X18") aluminum rims are fitted with 80/100-21 front and 110/90-18 rear tires, selected for their optimal off-road grip. Delivered with the GST MX-3 2024 plastic kit, this adult 300cc motocross combines an assertive racing look with maximum rider protection, all with the rigor and expertise that XtremRS brings to every product.

Gearbox: 5 speeds to optimize every adult motocross outing

The transmission of this adult 300cc motocross features a 5-speed gearbox (1-N-2-3-4-5) with a multi-plate manual clutch, giving you total control over every section of the track and the ability to calibrate your gears according to the terrain and your riding style. The final drive, consisting of a 13-tooth front sprocket, a 45-tooth rear sprocket, and a #520 chain, ensures efficient and direct power transfer from the engine to the wheels, preserving the characteristic liveliness of your adult 300cc motocross. This ratio has been designed to offer a good balance between low revs and power build-up, ideal for tackling climbs and technical corners without losing dynamism. Regular maintenance of the chain and gears is recommended to preserve the longevity of the transmission — our XtremRS team is at your disposal to guide you on proper maintenance practices and provide you with suitable replacement parts.

Brakes: reliable and powerful braking for your adult 300cc motocross

Daily safety on an adult 300cc motocross relies above all on exceptional braking. The front brake features a dual-piston caliper and a 260 mm disc, offering powerful and progressive bite even in the most demanding conditions and the fastest technical sequences. At the rear, a single-piston brake with a 240 mm disc completes the system for a perfect balance between braking power and rear-end control. This twin-disc setup guarantees short and reliable stops, essential for tackling descents and turns with complete confidence. XtremRS places paramount importance on the safety of its riders: every adult 300cc motocross is checked before shipment, and our customer service remains available to assist you with brake maintenance, the choice of wear discs, and necessary spare parts.

Suspensions: adjustable damping at the service of your adult 300cc motocross

The suspensions of this adult 300cc motocross have been designed to absorb the roughest terrain with remarkable precision and optimal comfort. Up front, a 53/58 mm inverted hydraulic fork with 880 mm of travel, adjustable in compression and rebound, adapts finely to your riding style and the type of terrain encountered, whether technical track or rough terrain. At the rear, a 480 mm gas shock absorber, also adjustable and mounted on a suspension linkage, ensures exceptional comfort and stable support for the adult 300cc motocross in corners and jumps, limiting the sensation of diving. These high-performance suspensions, combined with the 80/100-21 front and 110/90-18 rear tires, offer consistent grip and serene riding on all terrains. At XtremRS, we recommend regularly checking air pressure and rebound settings to maintain optimal performance — contact our team for personalized advice on tuning your adult 300cc motocross and benefit from our field expertise.
