Review CHANG JIANG Frame Chassis R71 Chinese Made Cj fits CJ750 M72 750

The **Chang Jiang CJ750 (Model 02-0034, Frame Chassis M72/R71)** is a robust and versatile motorcycle designed for riders seeking a blend of performance, durability, and practicality. Built upon the proven foundation of the CJ750 series, this model stands out as a true workhorse, engineered to excel in both urban commuting and off-road adventures. The frame chassis, a critical structural component, is meticulously crafted from high-strength steel, ensuring a balance of rigidity and flexibility to absorb road imperfections while maintaining stability at high speeds. The M72 and R71 variants offer distinct riding experiences, with the M72 favoring a more upright, ergonomic seating position ideal for long-distance travel and city riding, while the R71 adopts a slightly more aggressive, forward-leaning posture, catering to riders who prioritize sportier handling and agility.

Under the hood, the CJ750 houses a **748cc air-cooled, single-cylinder engine**, a design choice that emphasizes reliability and low-maintenance operation. This engine delivers a smooth and linear power delivery, producing approximately **40-45 horsepower**, which is ample for highway cruising, towing light loads, or navigating rough terrain. The four-stroke cycle ensures efficient fuel consumption and reduced emissions, making it an economical choice for daily use. The engine s robust construction, paired with a robust clutch and multi-plate wet clutch system, allows for seamless gear shifts and improved durability, even under demanding conditions. The transmission features a **five-speed gearbox**, providing riders with precise control over acceleration and speed, whether they are maneuvering through tight city streets or tackling winding mountain roads.

The CJ750 s suspension system is another standout feature, designed to adapt to a variety of riding conditions. The **front telescopic fork** and **rear swingarm with adjustable shock absorber** work in tandem to deliver a comfortable and controlled ride. The front fork is engineered to absorb impacts from uneven surfaces, while the rear shock can be fine-tuned to suit different rider preferences and payloads, ensuring optimal stability and comfort. The braking system is equally impressive, featuring **dual disc brakes** at the front and a single disc brake at the rear, all paired with reliable hydraulic calipers. This setup provides strong stopping power and consistent performance, even in wet or slippery conditions, enhancing rider confidence and safety.

The CJ750 s chassis is further enhanced by its **dual-cradle frame design**, which not only contributes to the motorcycle s structural integrity but also allows for easy access to critical components for maintenance and repairs. The frame s design also accommodates a **spacious fuel tank**, typically holding around **15-18 liters**, which translates to extended range for long journeys without frequent refueling stops. The motorcycle s **dual-seat configuration** and adjustable footpegs make it an excellent choice for riders of varying heights, as well as for passengers seeking comfort during extended rides. The ergonomic handlebars and grips are thoughtfully positioned to reduce fatigue, while the **upright riding position** minimizes strain on the back and neck, making the CJ750 a comfortable option for both solo riders and those sharing the journey.

Beyond its technical specifications, the CJ750 is celebrated for its **durability and low-cost ownership**. This motorcycle is built to withstand the rigors of daily use, from commuting in urban environments to venturing off-road on dirt trails or gravel paths. Its simple yet effective design translates to fewer mechanical complexities, reducing the likelihood of costly repairs and extending the lifespan of the machine. The CJ750 s reputation for reliability has made it a favorite among riders in regions where motorcycles are subjected to harsh conditions, including dust, mud, and extreme temperatures. Additionally, the widespread availability of spare parts and aftermarket accessories ensures that owners can easily customize their CJ750 to suit their specific needs, whether it s upgrading the exhaust system for improved performance or enhancing the lighting for better visibility.

In summary, the **Chang Jiang CJ750 (02-0034, Frame Chassis M72/R71)** is a versatile and hardworking motorcycle that bridges the gap between practicality and performance. Its sturdy frame, efficient engine, and thoughtful design elements make it a dependable companion for riders who demand both functionality and durability. Whether navigating city streets, cruising along highways, or exploring off-road trails, the CJ750 delivers a balanced riding experience that combines comfort, control, and enduring reliability. For those seeking a motorcycle that can handle it all without compromising on ease of use or cost-effectiveness, the CJ750 stands as a testament to Chang Jiang s engineering prowess and commitment to creating machines built to last.

### **Pros and Cons of Buying a Chang Jiang CJ750 Frame/Chassis (M72/R71 Models)**

1. **Reliability and Durability** The CJ750 is a well-known Chinese motorcycle brand that has been producing robust, off-road-capable bikes for decades. The M72 and R71 models are particularly durable, designed for rugged use, and built to withstand harsh conditions.

2. **Off-Road Capability** The frame and chassis are engineered for off-road performance, with strong suspension, knobby tires, and a sturdy construction. This makes it suitable for trails, dirt roads, and light adventure riding.

3. **Affordability** Compared to many Western or Japanese off-road motorcycles, the CJ750 is significantly cheaper, making it an attractive option for budget-conscious buyers who still want a capable bike.

4. **Easy Maintenance and Repairs** Chinese motorcycles, including the CJ750, are generally easier to work on than some Western brands. Parts are widely available, and mechanics familiar with Chinese bikes are common in many regions.

5. **Good for Beginners** The bike is simple to operate and maintain, making it a good choice for riders who are new to off-road or dual-sport riding.

6. **Customization Potential** The frame and chassis can be modified for different purposes, such as adding aftermarket suspension, exhausts, or even converting it into a more street-friendly bike.

7. **Strong Engine Performance** The 750cc air-cooled single-cylinder engine (depending on the model) provides decent power and torque, suitable for both on-road and off-road use.

8. **Resale Value (Compared to Similar Bikes)** While not as high as Japanese or European brands, the CJ750 retains a decent resale value, especially in markets where Chinese bikes are popular.

---

1. **Build Quality and Finishing** While the bike is durable, some buyers report that the plastic and metal finishes are not as refined as those on Western brands. Rust can be an issue if not properly maintained.

2. **Comfort for Long Rides** The ergonomics of the CJ750 are not optimized for long-distance comfort. The seating position and handlebar height can be uncomfortable for extended on-road riding.

3. **Fuel Efficiency** The 750cc engine consumes more fuel than smaller bikes, making it less efficient for daily commuting or long trips.

4. **Noise and Vibration** The air-cooled single-cylinder engine can be noisy and vibrates more than modern liquid-cooled engines, which may lead to fatigue during long rides.

5. **Limited Aftermarket Support** While parts are available, the aftermarket for CJ750 is not as extensive as for Japanese or European bikes. Finding specialized components (e.g., high-performance exhausts, suspension) may be difficult.

6. **Riding Position** The upright riding position is not ideal for high-speed stability on paved roads, making it less suitable for aggressive on-road riding.

7. **Weight** The bike is heavier than many modern dual-sport bikes, which can affect maneuverability, especially in tight off-road conditions.

8. **Electronics and Modern Features** The CJ750 lacks advanced features like ABS, traction control, or digital instrumentation found on newer bikes, which can be a drawback for modern riders.

The **Chang Jiang CJ750 (M72/R71) frame/chassis** is a solid choice for riders who prioritize **durability, off-road capability, and affordability** over modern comfort and advanced features. It is best suited for:

- **Off-road enthusiasts** who need a rugged, reliable bike for trails and dirt roads.

- **Budget-conscious buyers** who want a capable motorcycle without spending as much as on Western brands.

- **Beginners or hobbyists** who are willing to trade some comfort for a no-frills, hardworking machine.

However, if you plan to **ride primarily on paved roads, seek long-distance comfort, or want modern features**, you may find better alternatives elsewhere. The CJ750 is not a premium bike but serves a specific niche well.

---

- **Buy if:** You need a **durable, off-road-focused bike** on a budget, are okay with basic comfort, and don t mind some noise and vibration.

- **Avoid if:** You want a **comfortable, high-speed, or feature-rich** motorcycle, or if you prioritize modern ergonomics and electronics.

- **Consider alternatives if:** You re open to spending slightly more for a **dual-sport bike (e.g., Honda CRF700L, Yamaha XT660R, or Royal Enfield Himalayan)** for better on-road comfort and off-road capability.

For the best experience, ensure proper maintenance (especially rust prevention) and consider upgrading suspension or ergonomics if you plan to use it for mixed riding.
