Applications
- Urban commuting: Used for daily commuting on urban roads; the 80 km/h max speed falls within the permitted speed range on urban roads.
- Short-distance travel: Suitable for short trips on township roads and unpaved surfaces; the 115 mm ground clearance and 17-inch wheels allow the vehicle to clear common road obstacles such as speed bumps and manhole covers.
- Light carrying: The underbone layout provides a front footboard area and a rear seat, allowing one passenger or a small amount of luggage.
FAQ
Q1: Why does the vehicle retain a kick start?
A: The kick start enables engine starting when the battery is discharged or in low-temperature conditions, and serves as a backup to the routine electric start. It requires no electrical power and adds little to vehicle cost and weight.
Q2: How do drum brakes differ from disc brakes in use and maintenance?
A: Drum brakes are enclosed structures, so dust and moisture have little effect on braking performance. Their friction liners last longer in dusty conditions, and replacement cost is lower than that of disc brakes; the trade-off is lower heat dissipation during continuous downhill braking.
Q3: What are the operating limits of the air-cooled engine?
A: An air-cooled engine relies on airflow during riding for cooling and is suited to continuous operation at low and medium speeds. This engine has no liquid-cooling system and fewer components than liquid-cooled units; routine maintenance consists of oil changes, air-filter cleaning, and checking the chain and brakes.
