Engine & performance concept
At the core of the S9-Z300 RACE is Hengjian’s Z300 two-stroke powerplant, a 293 cm³ single-cylinder engine used across the brand’s 300-class off-road configuration follows the proven layout of the earlier S8 Z300 platform: a liquid-cooled 2-stroke with modern porting, performance expansion chamber and a race-oriented carburetor.
| Engine type | Single-cylinder, 2-stroke, liquid-cooled Z300 platform |
| Displacement | Approx. 293 cm³ (Z300 engine family) |
| Induction | Carburetor (tunable jetting for different altitudes and riding conditions) |
| Power output | Factory figures around 37 kW (about 50 PS) for the Z300 configuration, depending on market specification. |
| Combustion | Two-stroke with performance-oriented port timing |
This engine concept is aimed at delivering strong mid-range torque, rapid throttle response and a lively top-end, making the S9-Z300 RACE suitable for riders who prefer the character and serviceability of a carbureted 2T enduro over larger four-stroke alternatives.
Chassis, wheels and ergonomics
The S9-Z300 RACE carries over the compact dimensions and off-road-focused ergonomics familiar from previous Z300-based enduro models, while introducing detail updates in suspension and ready-to-ride weight targets for S9 and S8 300-class enduro models lie in the 118–120 kg range, depending on specification and regional equipment.
- Race-ready enduro frame designed for balance between high-speed stability and precise low-speed control in ruts, roots and rocks.
- 21" front / 18" rear wheel combination with off-road tyres, the standard in enduro competition and ideal for mixed terrain.
- Long-travel, fully adjustable off-road suspension (inverted front fork and rear monoshock) tuned for enduro and cross-country stages.
- Powerful hydraulic disc brakes front and rear, matched to the chassis for controlled stopping on steep downhills and slippery surfaces.
- Ergonomics oriented toward active riding: narrow mid-section, generous ground clearance and a tall, supportive seat height typical of modern race enduros.
Race-focused equipment
As the race variant within the S9 2-stroke family, the S9-Z300 RACE is specified to emphasise durability and handling in competition environments:
- Extended use of CNC-machined components (such as triple clamps, footrests or protective elements, depending on configuration) for strength, precision and visual impact.
- High-spec off-road handlebar, controls and levers suitable for intensive enduro and hard enduro riding.
- Modern plastics and graphics with sharper bodywork compared to earlier Z300 generations, reflecting the design direction of the S9 platform.
- Electrical system configured for off-road competition use, with the possibility of different lighting and cockpit setups depending on regional configuration.
Typical use cases
The HENGJIAN S9-Z300 RACE is positioned as a dedicated off-road motorcycle rather than an everyday dual-purpose engine character, chassis layout and specification make it particularly suitable for:
- Classic enduro events with varied terrain, including forest stages, rocky climbs and technical singletrack.
- Hard enduro practice where low-speed control, tractable power delivery and strong cooling performance are important.
- Cross-country and hare & hound races that demand sustained high-speed sections combined with tight woods.
- Intensive training sessions for experienced riders who prefer the feel and maintenance style of a modern carbureted 2-stroke enduro.
Detailed final specifications for the S9-Z300 RACE are being introduced progressively as the S9 platform enters different markets, with the core concept remaining a 293 cm³ Z300-based two-stroke race enduro built for serious off-road performance.
