Light, sharp and exceptionally honest in its handling, the MINSK ERX 300A is built for riders who don’t divide their routes into “road” and “off-road.” It is a versatile platform that combines carefully engineered geometry, minimal weight, and reliable mechanics proven in real-world conditions.
At the heart of the model is a carefully engineered balance: enough power to drive confidently out of corners and tackle climbs, combined with a lightweight construction that allows complete control of the motorcycle on narrow trails, in sand, or over rough terrain. With 330 mm of ground clearance and a 990 mm seat height, the MINSK ERX 300A provides excellent visibility and freedom of movement wherever the asphalt ends.
The MINSK ERX 300A is built around the proven single-cylinder ZONGSHEN PR300 engine with a displacement of 271.3 cc, producing 22 hp at 8,500 rpm and 22 Nm at 6,500 rpm. The engine is paired with a 6-speed transmission, delivering confident torque across a wide rev range and predictable throttle response. The simple air-cooling system enhances reliability and reduces maintenance requirements — an important advantage when riding away from the city.
A curb weight of just 115 kg, combined with a 1,460 mm wheelbase, results in responsive and agile handling. The suspension is designed for real-world use: a 41 mm inverted fork with 175 mm of travel and an adjustable rear shock absorber allow the motorcycle to be adapted to both riding style and terrain.
21/18-inch spoked wheels fitted with off-road tires provide full control when riding across challenging terrain.
The MINSK ERX 300A is not a compromise between the city and the off-road. It is a tool that feels equally at home in both worlds.
Features ERX 300A
6-speed transmission with a multi-plate wet clutch, engineered for precise throttle and torque control at low speeds as well as during more dynamic riding.
Lightweight chassis built around a lightweight frame and aluminum swingarm, reducing overall weight while increasing structural rigidity.
Disc brakes with floating calipers — 2-piston front / 1-piston rear — deliver predictable, controlled braking across a wide range of riding conditions.
High-strength CNC-machined clutch and brake levers. Made from aluminum and designed to withstand impacts in a crash, these folding levers help minimize the risk of breakage. Instead of bending or snapping on impact, the levers fold outward and quickly return to their original position once the force is released. Anodized finishes provide additional corrosion protection and extend service life.
Full lighting package, including headlight, turn signals, rear light, license plate illumination and rear fender.
NIBBI 34 carburetor delivers strong performance under high loads, reliable everyday operation and straightforward adjustment of its operating parameters.
