● 通用型后悬挂，后悬挂规格与常规CB机型一致，整车匹配性好。
● 大容积废气迷宫，体积大，油气分离效果更好，减少机油消耗，减低排放。
● 整体式支架+多风道气缸头，热稳定性更好，声音商品性更优。降低发动机整机热负荷，延长发动机使用寿命。
● 高滚流气道，充气效率高，混合更充分，高效燃烧，低速扭矩更大，动力更强劲，油耗更低。
● PVD活塞环，一环、二环、刮片环PVD处理，摩擦系数低，高耐磨及高耐腐蚀性，提升使用寿命。
● 前置启动电机，电机散热性好，维护保养更便利。提升整车布置空间，有利于进气系统布置。
● 新一代换档机构，大变速鼓+KE系列换档机构，换档舒适性好。
● Large-diameter roller rocker arms reduce friction and mechanical losses, delivering stronger engine performance. Large-diameter needle bearings offer extended service life.
● Lightweight pistons with back-cooling technology minimize secondary inertia forces, improving vibration comfort. This design also reduces thermal loads on pistons and cylinder blocks, enhancing durability.
● Offset cylinder layout combined with centrifugal cast liners reduces piston-to-cylinder wall side thrust, lowering friction losses and fuel consumption. The liner bonds more tightly to the base material with increased contact area, offering high thermal stability, reduced oil consumption, and improved fuel economy.
● Universal rear suspension system matches standard CB-series specifications, ensuring excellent vehicle compatibility.
● Large-volume crankcase ventilation labyrinth chamber provides superior oil-gas separation, reducing oil consumption and emissions.
● Integrated bracket with multi-channel cylinder head improves thermal stability and acoustic quality. It lowers overall engine thermal load, extending engine service life.
● High-tumble intake ports enable higher charging efficiency and more complete air-fuel mixing, achieving efficient combustion, increased low-end torque, improved power output, and lower fuel consumption.
● PVD-coated piston rings (top, second, and oil scraper rings) feature low friction coefficient, high wear resistance, and excellent corrosion resistance, significantly extending service life.
● Front-mounted starter motor ensures better heat dissipation and easier maintenance. It also frees up space for layout optimization, especially for intake system design.
New-generation shifting mechanism with large shift drum and KE-series shift system delivers smoother, more comfortable gear changes.
