Review KAWASAKI 86-00 Input Shaft Assembly fits KX80

The **Kawasaki 13127-1154 86-00 Shaft for KX80** is a meticulously engineered, high-performance drive shaft designed specifically for Kawasaki s iconic KX80 dirt bike, a model produced in the mid-1980s. This particular shaft, part number **13127-1154**, corresponds to the **1986-2000 model year** of the KX80, ensuring an exact fit for riders seeking to restore or upgrade their bike s drivetrain. Crafted from durable, high-grade steel, this shaft is built to withstand the rigors of off-road use, delivering reliable power transfer from the transmission to the rear wheel while maintaining structural integrity under heavy loads and rough terrain. The **86-00 designation** indicates compatibility with the early iterations of the KX80, which featured a compact, lightweight chassis and a 79.8cc single-cylinder engine, making this shaft a critical component for maintaining optimal performance and handling. Whether replacing a worn-out original shaft or enhancing the bike s durability for aggressive riding, this Kawasaki part ensures smooth operation, reduced vibration, and improved longevity of the drivetrain. Its precise engineering aligns with Kawasaki s reputation for precision and performance, making it an essential replacement for enthusiasts and mechanics alike who demand nothing less than perfection in their restoration or modification projects.

### **Pros and Cons of Buying a Kawasaki 13127-1154 (1986 2000 Model) Shaft-Drive KX80**

#### **Pros**

1. **Affordability** The KX80 is one of the most budget-friendly dirt bikes from Kawasaki, making it an attractive option for beginners, kids, or those on a tight budget. Parts and labor costs are also relatively low compared to larger bikes.

2. **Lightweight and Easy to Handle** Weighing around **100 110 lbs (45 50 kg)**, the KX80 is one of the lightest in its class, making it ideal for younger riders (typically ages 8 12, depending on height and experience). Its small size allows for easy maneuverability in tight trails and on small jumps.

3. **Simple and Reliable Engine** The **air-cooled, single-cylinder, 4-stroke engine** (72cc) is straightforward in design, which means it s easier to maintain than a 2-stroke or larger 4-stroke. It s also less prone to catastrophic failure compared to more complex engines.

4. **Durable and Rugged Build** Kawasaki used a **shaft-drive system** (instead of a chain) on this model, which reduces maintenance (no chain adjustments, lubrication, or wear) and makes it more durable in rough conditions. The shaft drive also helps protect the engine from debris.

5. **Good for Learning** The KX80 s manageable power (around **10 12 hp**) is perfect for teaching balance, throttle control, and basic riding techniques without overwhelming a beginner.

6. **Easy to Modify** Since it s a simple bike, upgrades like **exhausts, carburetors, or suspension adjustments** are straightforward and cost-effective. Many aftermarket parts are available for performance or comfort improvements.

7. **Low Fuel Consumption** The small engine uses very little gas, making it economical for short rides or practice sessions.

8. **Resale Value** While not high, the KX80 holds up well in the used market, especially if well-maintained. It s a common bike, so finding parts and buyers is relatively easy.

9. **Minimalist Maintenance** With no chain to adjust, fewer moving parts than a 2-stroke, and a simple carburetor (on later models), upkeep is less time-consuming than on more complex bikes.

10. **Great for Cross-Country or Trail Riding** Its lightweight and nimble nature makes it suitable for **enduro-style riding** where agility is more important than raw power.

#### **Cons**

1. **Limited Power for Serious Riding** The **72cc engine** produces very little power (around **10 12 hp**), making it unsuitable for **jumping, racing, or riding on steep climbs** with an adult rider. It s best for **light trail riding, practice, or kids use**.

2. **Outdated Technology** Being from **1986 2000**, the bike lacks modern features like **disc brakes (early models had drum brakes), electronic fuel injection (EFI), or advanced suspension tuning**. This can make braking and handling less precise compared to newer bikes.

3. **Poor Braking (Early Models)** The **drum brake** on the original KX80 (pre-1990) is weak and ineffective, requiring an **aftermarket disc brake conversion** for better stopping power. Even with upgrades, it won t match modern standards.

4. **Comfort Limitations** The **small seat, minimal suspension travel (around 6.7 inches front, 6.3 inches rear)**, and lack of ergonomic adjustments make long rides uncomfortable. The **upright riding position** is not ideal for endurance riding.

5. **Fuel Efficiency is Misleading** While it uses little gas, the **small tank (1.3 gallons)** means frequent refueling stops, which can be inconvenient on longer rides.

6. **Reliability Issues with Age** Even with proper maintenance, **rubber seals, gaskets, and bearings** will eventually wear out. The **shaft drive** is durable, but the **transmission and clutch** can become sluggish over time.

7. **Limited Aftermarket Support** While parts exist, **modern aftermarket upgrades (e.g., high-performance exhausts, ECU tuning)** are rare compared to more popular bikes like the KX250 or CRF250.

8. **Not Suitable for Adults** Unless the rider is **very small (under 120 lbs / 54 kg)**, the bike will feel **underpowered and unstable**, especially at higher speeds.

9. **Potential for Rust (If Neglected)** Older bikes, especially those stored outdoors, can suffer from **rust on the frame, suspension, or shaft drive** if not properly maintained.

10. **No Modern Safety Features** Lack of **traction control, ABS, or advanced suspension damping** means the bike relies on rider skill for stability, which can be risky for inexperienced riders.

### **Conclusion**

- **Beginner riders (especially kids aged 8 12)**

- **Budget-conscious buyers** who need a simple, low-maintenance bike

- **Light trail riding, practice, or casual use**

- **Those who prefer a chain-free, durable shaft-drive system**

- **Adult riders** (unless very small and only for light use)

- **Serious off-road enthusiasts** needing power or modern handling

- **Long-distance or endurance riding** due to comfort limitations

- **Racers or jumpers** who require more performance

If you find one in **good condition with a disc brake upgrade**, it can be a **fantastic starter bike or a fun project bike**. However, if you re looking for **modern features, power, or adult-sized comfort**, a newer **Kawasaki KX65, CRF125, or even a used KX85** might be a better investment.

---

### **Final Recommendation**

You need a **cheap, simple bike for a young rider** (with proper safety gear).

You want a **low-maintenance, durable shaft-drive bike** for light trail use.

You re okay with **limited power and outdated tech** in exchange for affordability.

You re an **adult rider** expecting more power or comfort.

You plan to **ride aggressively, jump, or race**.

You want **modern braking, suspension, or fuel efficiency**.

- **Starter bike for a kid** (with proper supervision).

- **Project bike for restoration/modification** (if you enjoy working on older machinery).

- **Budget-friendly trail bike** for occasional, light use.

If you re set on this bike, **inspect it thoroughly for rust, clutch wear, and suspension condition** before purchasing. Consider **upgrading the brakes** if it s an older model. Otherwise, a **newer KX65 or CRF125** may offer better value for slightly more money.
