● 单缸、四冲程、风冷、电启动发动机
● 采用单缸四气门、SOHC结构，进气阻力小、充气效率高、动力强劲
● 采用指形滚子摇臂、气缸偏心技术，减少功率损失、寿命更长、动力强劲
● 采用小体积高性能起动电机，电起动声音小
● 采用二次补气结构，使废气中的有害气体进行二次氧化，排放污染物低
● 采用离心式油气分离循环技术，废气排放及机油消耗更低
● 采用最新平台换挡机构，换挡更省力、到位感与舒适性更好
● 采用外置纸质精滤器对整机机油过滤，区别于离心式部分过滤结构，热机及各运动副磨损更小，可靠性更高
● 采用加强型主副轴，提升齿轮疲劳强度、延长使用寿命
● 采用18滚柱起动超越离合器，起动更可靠
● Single-cylinder, four-stroke, air-cooled, electric starting engine.
● It adopts a single-cylinder four-valve, SOHC structure, with low air intake resistance, high inflation efficiency and strong power.
● It adopts finger roller rocker arm and cylinder eccentric technology to reduce power loss, longer life and strong power.
● Small size and high performance starter motor, electric starting sound is small.
● The secondary air supply structure is adopted to re-oxidize harmful gases in the exhaust gas and reduce the emission of pollutants.
● Adopting centrifugal oil and gas separation circulation technology, exhaust emissions and oil consumption are lower.
● Adopting the latest platform shifting mechanism, shifting is more labor-saving and provides better in-place feel and comfort.
● An external paper fine filter is used to filter the entire engine oil. Different from the centrifugal partial filtration structure, the heat parts and each kinematic pair have less wear and higher reliability.
● Adopt reinforced main and counter shafts to improve gear fatigue strength and extend service life.
● 18-roller starting overrunning clutch, starting is more reliable.
