As a popular mini bike in the current leisure and entertainment market, the top performance of the MB40 stems from the perfect combination of multiple core technical parameters and designs. In terms of power, it is equipped with a water-cooled four-stroke 40cc engine, which delivers a peak power of 3.1kW (approximately 4.2 horsepower) at 8,500 RPM. Combined with a curb weight of only 45 kilograms, its thrust-to-weight ratio is significantly better than that of similar products, enabling it to accelerate from 0 to 40km/h in just 4.5 seconds and reach a top speed of 50.5km/h. For instance, in the mini motorcycle endurance race held at the California Karting Park, the models equipped with the same engine demonstrated the durability of their power systems by running continuously for 200 hours without any faults. This reliability attracted a large number of enthusiasts.
Its high-strength chromium-molybdenum alloy frame has been optimized through FEA finite element analysis, featuring a rated load capacity of 100kg. It also adopts a long-stroke hydraulic front fork (120mm stroke) and a single rear shock absorber with adjustable preload. In the BMX off-road track tests, it has absorbed over 70% of the impact energy from obstacles 10cm high, significantly enhancing its passability on complex terrains. According to the statistics of the “China Motorcycle Quality Report”, the fatigue life of the frame with a similar structure exceeds 15,000 kilometers, far higher than the industry average of 8,000 kilometers. Users have reported that the deformation of the chassis after frequent jumps is less than 1.2mm, demonstrating outstanding stability.
The security configuration is also supported by professional data. The front and rear hydraulic disc brake system, paired with 175mm ventilated brake discs and equipped with dual-piston calipers, can achieve a braking distance of only 14.3 meters from a speed of 30km/h to a standstill on a slippery road surface with a friction coefficient of 0.45, which is 23% shorter than the drum brake system. The key bearings adopt IP67 grade seals, maintaining stable lubrication viscosity within the ambient temperature range of -15℃ to 45℃. In a test on a certain track in Guangdong in 2023, after 30 consecutive emergency brakes, the brake disc temperature of this braking system was still controlled within 210℃, with a thermal attenuation rate of less than 15%, which was better than the industry’s warning threshold of 30%.
It has a prominent economic advantage in daily use. The measured combined fuel consumption is 1.7L/100km, and with a 5.5L fuel tank capacity, the single-charge range exceeds 320 kilometers. The maintenance cycle is up to 200 hours or 5,000 kilometers. Use 10W-40 engine oil that complies with JASO MA standard, and only 0.8 liters are needed for a single change. The operation data of a certain leasing company in Shenzhen shows that the average annual maintenance cost of the MB40 fleet is 42% lower than that of other competing products, and the energy cost per 100 kilometers is only 3.6 yuan. Its compact size (wheelbase 980mm/ seat height 560mm) makes it easy to store and can be placed in the trunk of a car (with a space utilization rate of 85%). At the 2024 Leisure equipment exhibition, the actual measurement of the packing and disassembly process was less than 120 seconds.
At the user experience level, the ergonomic design is optimized based on data from Asian users. The 780mm wide handlebars, combined with a 28° steering Angle, have a turning radius as low as 1.9 meters. The wear-resistant and anti-slip seat cushion has passed 400,000 pressure tests without deformation, and the filling density is 55kg/m³ to ensure long-distance comfort. As a leisure mini bike, the MB40 strikes a balance between handling accuracy and comfort in its design. User research shows that 95% of riders report significantly less fatigue in their arms and legs than other models.
