近几年我国生产的轻便摩托车,按变速方式分为有级变速式和无级变速式。有级变速的轻便摩托车,变速挡位一般不超过两个。其优点是结构简单,使用可靠,传动效率高,燃油消耗量低;缺点是操纵动作复杂,驾驶不方便,噪声较大。该种车适合道路稍差、距离稍远的 In recent years, China’s production of lightweight motorcycles, according to the variable speed mode is divided into a variable speed and continuously variable type. A speed shift light moped, gear shift generally no more than two. Its advantages are simple structure, reliable use, high transmission efficiency, low fuel consumption; the disadvantage is the manipulation of complex operations, driving inconvenient, larger noise. The kind of car suitable for the road a little worse, a little further away
