Description |
| 1 |
New‑style appearance: |
Square‑shaped one‑piece cylinder‑head & cylinder block, powerful and magnificent look. |
| 2 |
Toothed timing‑chain drive: |
7‑piece toothed‑chain ensures stable valve‑train operation and low overall engine noise. |
| 3 |
Hot-assesmbled crankcase |
Hot‑assembled crankcase with locking‑pin structure, reduces crankshaft axial‑play noise and improves overall engine performance. |
| 4 |
Built‑in oil‑cooling design: |
Innovative cylinder‑head internal oil‑circuit structure, greatly lower cylinder‑head operating temperature. |
| 5 |
Balance‑shaft system: |
Front‑mounted balance‑shaft offsets primary inertial force from crank reciprocating movement, reduces engine vibration and enhances riding comfort. |
| 6 |
High‑output oil‑pump: |
Oil‑pump flow increased by 20 %, better lubrication and cooling for friction pairs and cylinder‑head. |
| 7 |
Optimized cylinder‑head: |
Enlarged valves, optimized port and cam‑shaft profile; improved power‑torque and acceleration performance. |
| 8 |
High‑quality piston‑rings: |
Dual DLC+PVD coated piston‑rings with excellent wear‑resistance and long‑life, mitigate oil‑burning; piston crown micro‑arc‑oxidation, skirt molybdenum‑disulfide treatment. |
| 9 |
High‑temperature resistant valve: |
Adopt 751‑grade high‑temp exhaust‑valve material for good high‑temperature mechanical property. |
| 10 |
Roller rocker‑arm: |
Equipped with ball‑bearing to reduce friction loss between camshaft and rocker contact point. |
| 11 |
Thickened crankshaft bearings, shortened connecting‑rod: |
Reduce reciprocating inertial force and eliminate engine knocking risk. |
| 12 |
Enlarged shift‑drum: |
Larger‑diameter shift‑drum with mild‑slope groove for smoother gear‑shifting. |
| 13 |
Reinforced main‑shaft & counter‑shaft: |
Strengthen all transmission gears for high reliability. |
| 14 |
Crankshaft offset‑technology: |
Reduce piston side‑thrust, maximize combustion energy utilization and optimize fuel consumption. |
