Shandong Tuowei Locomotive Co., Ltd. is one of the most reliable manufacturers and suppliers of 300cc off road dirt bike in China. With a professional production team, we are able to meet the needs of the majority of our customers. Welcome to wholesale premium 300cc off road dirt bike made in China here from our factory.
The 300cc Off Road Dirt Bike is a purpose-built racing dirt bike developed for motocross circuits, closed-course competition, and high-intensity off-road training. Positioned under our Racing Dirt Bike series, model V2-CB300 pairs a 300cc four-stroke engine with a compact, competition-focused chassis to serve riders who value fast throttle response, predictable jumping behaviour, and repeatable lap performance. It is intended for adult riders and commercial operations-training schools, track rental fleets, and event organisers-that require a durable dirt bikes for adults solution rather than a casual recreational toy.
Engine Character: Response Over Raw Peak Power
On a motocross track, an engine is asked to do something very specific: deliver usable thrust the instant the throttle is opened, dozens of times per lap. This 300cc dirt bike is tuned around that requirement. Rather than chasing a high peak-horsepower figure, the 300cc four-stroke powerplant is developed for fast spool-up, using lightweight internal components to reduce rotating inertia so the engine revs quickly and settles back to a stable idle. The intake tract and exhaust system are matched to keep the mid-range full, which is the part of the powerband riders use most when exiting a corner and driving toward the next obstacle.
The practical benefit is timing. A rider can clear a jump face with a short run-up, correct a mistake mid-corner, or accelerate out of a rut without waiting for the engine to build revs. For training operators, faster throttle response also shortens the learning curve, because students receive immediate feedback from inputs instead of a delayed surge.
Chassis: Engineered Around Jump and Landing Loads
A motocross dirt bike is stressed in ways a trail machine is not-repeated hard landings, aggressive weight transfer, and high lateral loads in berms. The V2-CB300 uses a compact, mass-centralised layout with reinforcement at the steering head and swingarm pivot to resist frame flex under those loads. Weight is kept close to the machine's centre so that the bike changes direction with less rider effort and feels balanced in the air.
Suspension is specified with long travel and controlled rebound damping, allowing the wheels to absorb take-off impacts and settle quickly after landing instead of bouncing and losing traction. This is why the bike feels stable on the face of a jump and composed on the landing ramp, two moments where poor chassis control usually causes crashes.
Brakes and Rider Contact Points
Stopping power matters as much as acceleration on a race course. This off road dirt bike is equipped with front and rear disc brakes that give progressive, repeatable lever feel, letting a rider brake deep into a corner and release smoothly without upsetting the chassis. Control levers are positioned for use with gloved hands and can be adjusted to suit different hand sizes.The seat and bodywork use a narrow profile so the rider can shift weight forward or backward freely-essential for controlling traction on acceleration and keeping the front wheel light over obstacles. These ergonomic details turn raw performance into something a rider can actually use consistently, lap after lap.
Serviceability for Commercial Fleets
For rental, training, and event businesses, uptime is revenue. This competition dirt bike is designed with straightforward maintenance in mind: accessible air-filter housing, easy chain tension checks, and wear components that follow common industry dimensions. Standardised components mean local workshops can service the machine without waiting for specialised tooling.
We support this further with an on-site spare parts warehouse holding core components, so repeat orders and urgent parts requests can be fulfilled without long delays. Bulk buyers also receive product manuals, maintenance guides, and spare parts lists to set up local service capability.
Manufacturer Credibility and Supply Support
Shandong Tuowei Motorcycle has manufactured complete motorcycles since 2000. Every V2-CB300 is assembled on a controlled production line covering frame welding, precision component fitting, powertrain installation, and end-of-line inspection. Before shipment, each unit passes power output verification, brake system testing, electrical circuit diagnostics, and a simulated road test-evidence-based checks that reduce the risk of defective units reaching your warehouse.
The model is supplied in orange, red, silver, and gold, with OEM/ODM customisation covering colour schemes, accessory combinations, and logo branding. We support wholesale 300cc dirt bike programmes as well as trial container orders, and our export team manages documentation, packing, and loading supervision.

FAQ
Q: Is this motocross dirt bike suitable for taller or heavier adult riders?
A: Yes. The 300cc platform offers enough torque to carry heavier riders without constant clutch work, and the chassis geometry is tuned for adult proportions. Riders above average height usually find the ergonomics comfortable; we can discuss handlebar and seat-height options for specific market requirements.
Q: Can it be used for trail riding as well as motocross?
A: It is optimised for track and competition use, but its durable off-road chassis and suspension travel also handle trail and open-terrain riding. If your customers mainly ride long-distance trails, we can advise on gearing and tyre specifications to suit that application.
Q: What routine maintenance does the bike require?
A: Standard items include air-filter cleaning, chain tension and lubrication, oil changes, and brake-pad inspection. Because components follow common dimensions, local workshops can perform these tasks easily, and we supply spare parts and remote technical guidance to support long-term operation.
Q: Do you accept custom branding for fleet or dealer orders?
A:Yes. We provide OEM/ODM services including custom colours, logo application, and accessory packages. Share your target market and estimated volume, and our team will prepare a configuration proposal and quotation.
Q: What quality checks are performed before shipment?
A: Every unit passes end-of-line inspection covering engine performance, braking system, electrical circuit and simulated road testing before leaving the factory. This process controls assembly precision and riding safety, and helps ensure consistent quality across bulk orders.
Q: Which markets do you export to?
A: Our motorcycles are exported to dozens of countries and regions across Southeast Asia, Africa, the Middle East, South America and Eastern Europe, serving distributors, wholesalers, brand traders and fleet buyers.
