In the open desert and sand dune areas, the performance advantages of gas dirt bikes are extremely significant. This type of terrain requires vehicles to continuously output high power to overcome the resistance of soft sand. A 450cc gas engine can provide over 50 horsepower, enabling the vehicle speed to be easily maintained at over 60 kilometers per hour on sandy slopes. In contrast, the battery discharge rate of electric off-road vehicles will increase by 300% under the same conditions, resulting in a sharp reduction in the driving range to less than 40 kilometers. According to the historical data of the Baja 1000 Trail Race, in the over 300-kilometer desert section, all the participating vehicles with a completion rate as high as 98% were gas-powered. Their powerful torque output was sufficient to handle sand dunes with a slope of over 30 degrees, and the power attenuation rate of the vehicles was less than 2%.
The ever-changing forest paths and rugged mountain roads are another perfect stage. The terrain complexity index here usually exceeds 80%, involving frequent acceleration, braking and climbing operations. The weight-to-power ratio of the gas off-road motorcycle reaches an astonishing 0.3 horsepower per kilogram, which means that the response time for its center of gravity shift is only 0.5 seconds, thus achieving precise control in continuous hairpin turns. Industry analysis shows that in endurance races similar to the West Virginia Mountains in the United States, drivers need to complete an average of 20 gear shifts per minute, while the gear shift life of a gas transmission exceeds 100,000 times, with a failure rate of less than 0.1%. A survey of forest road cyclists in the central and western regions shows that 85% of experienced riders believe that in an environment where the altitude suddenly changes by more than 500 meters, the linearity and controllability of the power output of gas engines far exceed that of electric systems.
When the environment becomes extreme, such as in muddy or slippery riverbed areas, the adaptability of gas off-road motorcycles becomes more prominent. The tread depth of its tires is usually over 25 millimeters. Combined with controllable power sliding tires, it can provide 15% more traction than electric motorcycles. In a marsh environment with humidity exceeding 90%, the gas intake system has been specially designed with a waterproof rating of up to IP67, ensuring that the engine can still operate normally when wading through water to a depth of 60 centimeters. Referring to the case of the 2023 Scottish Six-day Endurance Race, after continuous rainfall, the mud level index of the stage soared. Among the vehicles that completed the race, 95% were gas-powered models. The key reason for this was that the peak torque output range of gas engines covered 3,000 to 8,000 revolutions per minute, allowing riders to precisely control the rear wheel slip rate at a frequency of 40 times per minute. Thus maintaining the dynamic balance of the vehicle body.
Finally, for environments that require long-distance exploration and self-supply, such as vast grasslands or remote mountainous areas, the advantages of gas-powered off-road motorcycles are decisive. Its range easily exceeds 200 kilometers, and by carrying an additional 5 liters of spare fuel (weighing about 3.5 kilograms), the range can be instantly extended by 80 kilometers, and the energy replenishment time only takes 2 minutes. However, under the same load, the battery energy density limitation of electric vehicles limits their median effective range to only 120 kilometers. According to statistics from the Australian Inland Exploration Association, in over 100 exploration activities organized in the past decade, each covering a distance of more than 500 kilometers, the utilization rate of gas vehicles has been close to 100%. Their reliability has been ultimately verified in harsh environments with a temperature difference of over 40 degrees Celsius between day and night, and the average time between failures (MTBF) of the vehicles is over 500 hours.
