1凸轮4气门头，操作简单，动力输出大!
Superhead 4v+r(1凸轮4气门)
通过使用2个进气阀和2个排气阀各增加气门幕面积，实现高进气和排气效率。
为了达到原厂机头无法获得的高输出，在原厂机头形状设计中，平衡了 "中心塞"、"间隔夹角 "和 "压缩室形状 "端口形状。
燃烧室通过机械加工达到高精度。
最高级别的进排气效率
阀杆直径内：25mm×2/外：21.5mm×2
阀杆轴直径：内、外均为4.5mm
不等节距的气门弹簧，防止高转速下的喘振。
汽缸盖表面被漆成黑色。
由于包含了检查呼吸罩，可以通过单独购买 "集油箱套件 "来释放发动机的内部压力。
检查呼吸器盖`检查盖`l.气缸盖侧盖采用抛光铝压铸筒体处理。
锻造铝合金滚轮摇臂
降低与凸轮轴的摩擦阻力，使其运行更平稳
最大的功率输出可以保持在中速到高速范围内。
凸轮轴/气缸/活塞
自动减压凸轮轴
自动减压凸轮轴
在不给单元电机加负荷的情况下，可以顺利启动发动机。
采用的是全铝陶瓷Mexilinder。
孔径：63mm冲程57.9mm(正常)
陶瓷Mexilinder具有优越的耐久性、气密性和散热性。
缸体上有一个出油口通向机油冷却器，可以单独购买机油冷却器套件，防止机油温度升高。
缸体表面未涂银色。
高压缩铸铝活塞，压缩比为12.5:1。
活塞设计为高性能和耐用性。
活塞顶部经nc加工，精度高。
