| SN | Items | Description |
| 1 | Cooling system: | Off‑road‑special built‑in water‑channel design; integrated dynamic‑static water‑seal for consistent sealing performance. |
| 2 | Lubrication system: | Two‑stage filtration; coarse filter on left housing, detachable paper‑element fine filter on right cover. |
| 3 | Optimized balance‑shaft system: | Low‑vibration, comfortable riding; ground‑balance gear & spring‑damping structure to suppress gear noise. |
| 4 | Light‑weight piston & rings: | Piston crown micro‑arc‑oxidation, skirt molybdenum‑disulfide treatment; DLC+PVD piston‑rings to cut friction loss. |
| 5 | Valve‑train: | 1. 7‑piece toothed timing‑chain, low‑noise tensioner; 2. DOHC dual overhead camshaft, independent intake/exhaust cam; 3. tappet direct‑driven valves for high‑speed power and reliability. 4. Four‑valve design for higher charging‑efficiency. |
| 6 | Transmission system: | 6‑column‑7‑plate clutch with Fuji friction plates; large‑diameter shift‑drum for sensitive & reliable shifting. |
| 7 | Combustion optimization: | Four‑valve cylinder‑head, special‑shape combustion‑chamber, optimized port & cam profile for improved power‑torque output. |
| 8 | Cylinder- head | Reliable composite steel‑rubber gaskets for cylinder‑head, right‑cover and tensioner housing, reusable after disassembly. |
| 9 | Easy maintenance: | Split‑design right crankcase‑cover for fast clutch‑plate replacement. |
| 10 | Optional configuration: | Carburetor / EFI(36‑2T); 5‑speed(electric+kick) /6‑speed(electric‑start only). |
