7 250跨骑式系列 春兰250跨骑式系列摩托车采用顶置四气阀结构发动机。由于气阀数的增加,使进排气速度加快,换气效率提高,从而大幅提高了发动机的功率和转矩,使其动力更为强劲;V形双缸排列,水冷循环系统,使发动机运转更平稳、冷却更充分,性能更佳;压力油膜式主轴承,承载能力大大提高的同时,耐久寿命更有大幅度提高。 春兰250跨骑式摩托车的整车造型极具特色。大前伸角、高翘式车把、水滴形油箱、通体流线型车身线条结构、中空铝合金轮辋配以超宽扁平化真空轮胎。该款车在用料、做工上也很考究:所有镀铬件
7 250 straddle type Chunlan 250 straddle series motorcycle with overhead four-valve structure engine. Due to the increase of the number of gas valves, the speed of intake and exhaust gas is increased and the efficiency of ventilation is increased, thereby greatly improving the power and torque of the engine to make the power more powerful. The V-shaped two-cylinder arrangement and the water-cooled circulation system make the engine run More stable, more fully cooled, better performance; pressure oil film bearing, bearing capacity greatly improved at the same time, the durable life more substantial increase. Chunlan 250 straddle-type motorcycle car styling very distinctive. Large front angle, Alice-type handlebar, drop-shaped tank, the body streamlined body line structure, hollow aluminum alloy wheels with a wide flattened vacuum tire.
