Overview
Key Advantages
Zongshen NB300 Engine Platform
The NB300 (ZS174MN-5) is a proven 300cc single-cylinder engine with 19kW output and 24 N.m torque at 7,500 rpm. Widely used across the Chinese enduro segment, parts availability and service familiarity are well established — reducing after-sales friction for your dealership.
CNC-Machined Chassis Components
Steering stem, front and rear wheel hubs are CNC-machined. Combined with a 7-series aluminum alloy handlebar and aluminum alloy levers, this delivers tighter tolerances and a premium build feel that supports higher retail positioning.
Adjustable Suspension System
Double-adjustable rear suspension with 48mm inverted front forks (54-60-910 travel). End users can adapt ride characteristics to their weight and terrain preference without aftermarket upgrades — lowering your post-sale support costs.
Altitude-Friendly Fuel System
The PWK34 carburetor with 11.6:1 compression ratio provides reliable performance across elevation changes. A practical advantage for markets in mountainous regions where fuel injection alternatives add cost and complexity.
Full Hydraulic Braking
Front and rear hydraulic disc brakes with stainless steel exhaust. The braking system is consistent and predictable — a key safety and confidence factor for riders transitioning from smaller displacement bikes.
Shipping Efficiency
10 units per 40HQ container in SKD packaging (1,690 × 460 × 830 mm per unit). This container density directly reduces your per-unit landed cost compared to competitors shipping 6-8 units per container.
