Description |
| 1 |
Chain Drive |
7‑piece toothed timing‑chain, ensure stable valve‑train and low‑noise running. |
| 2 |
Cylinder Head Profile |
New one‑piece integrated cylinder‑head with clean‑cut outlook. |
| 3 |
Crankcase Thermal Assembly |
Hot‑assembled crankcase with locking‑pin structure, reduce crankshaft axial‑play noise. |
| 4 |
Brand-new Thermal Engine Structure |
Revised thermal‑management architecture: New cylinder‑head oil‑circuit layout, optimize cooling air‑duct and internal noise suppression. |
| 5 |
Roller Valve Rocker Arm |
Roller rocker‑arm with ball‑bearing cam journal to cut friction and power loss. |
| 6 |
Lightweight Piston with Backside Cooling Design |
Light‑weight piston & piston back‑cooling: Reduce piston abrasion; prevent piston crown burn‑through and piston‑ring seizure. |
| 7 |
Balancing System |
Built‑in balance‑shaft system: Counteract primary inertial force from crank‑reciprocating movement, lower vibration and improve riding comfort. |
| 8 |
High-Quality Piston Rings |
Dual DLC+PVD piston‑rings for superior wear‑resistance and anti‑oil‑burning performance. |
| 9 |
High-Power Starter Motor |
High‑power starter‑motor, braking torque 2.2 N·m for easy cranking. |
| 10 |
Thickened Crankshaft Bearing & Optimized Connecting Rod Length |
Thickened crankshaft bearing & shortened connecting‑rod: Reduce reciprocating inertial‑force and suppress engine knocking. |
| 11 |
Optimized Camshaft Profile |
Optimized camshaft‑profile for enhanced power‑torque and acceleration performance. |
| 12 |
High-Temperature Resistant Valve Material |
751‑grade high‑temp exhaust‑valve material. |
| 13 |
Enlarged Shift Drum |
Enlarged shift‑drum for smoother gear‑shifting. |
| 14 |
Reinforced Main & Counter Shaft |
Reinforced main‑counter shaft and gears to raise transmission reliability. |
| 15 |
Crankshaft Offset Technology |
Crankshaft offset‑technology: Reduce piston side‑thrust and improve combustion‑efficiency and fuel economy. |
