### **Pros and Cons of Buying a Kawasaki F7/F5/F9 Big Horn (1970 1978) with a 46018-047 Ignition Coil (KE175/KD175)**

#### **Pros**

1. **Classic Aesthetic and Vintage Appeal**

The Kawasaki Big Horn is a well-designed, timeless motorcycle with a distinctive, retro look that appeals to enthusiasts of classic bikes. Its clean lines, chrome details, and simple yet elegant design make it a standout piece in any collection.

2. **Reliable and Well-Engineered Engine**

The **KE175 (1970 1974)** and **KD175 (1975 1978)** engines are air-cooled, single-cylinder, two-stroke designs that are known for their simplicity and durability. With proper maintenance, these engines can last for decades, especially if they have been well cared for.

3. **Lightweight and Maneuverable**

The Big Horn is a relatively light bike (around **200 220 lbs / 90 100 kg**), making it easy to handle, park, and transport. Its small size also contributes to its fuel efficiency and ease of riding in urban environments.

4. **Affordable to Maintain (Compared to Modern Bikes)**

Parts for the Big Horn are still available, though some may require sourcing from specialty vendors. Labor costs are generally lower than for modern bikes, and the lack of complex electronics means fewer potential failure points.

5. **Great for Learning or Casual Riding**

The bike s simplicity makes it an excellent choice for beginners or riders who prefer a straightforward, low-stress riding experience. Its smooth power delivery and forgiving nature also make it enjoyable for leisurely rides.

6. **Modding Potential**

While not as heavily modded as some modern bikes, the Big Horn has a dedicated fanbase that enjoys customizing it with aftermarket parts, paint jobs, and minor mechanical upgrades. The open-frame design allows for creative modifications.

7. **Historical Significance**

The Kawasaki F7/F5/F9 was one of the first Japanese motorcycles to gain widespread recognition in the U.S. and Europe. Owning one connects you to motorcycle history, particularly the early days of Japanese bike manufacturing.

---

#### **Cons**

1. **Limited Power and Performance**

The **175cc two-stroke engine** produces only about **12 15 horsepower**, which is adequate for casual riding but insufficient for highway speeds or aggressive riding. It struggles in strong headwinds and on steep climbs, making it more suited for city or park riding.

2. **Poor Fuel Efficiency (For Its Size)**

While two-stroke engines are fuel-efficient in theory, the Big Horn s **mixed-lube system** (oil mixed with gasoline) means you must add oil to the fuel, reducing overall efficiency. Expect around **80 100 mpg**, but with the added cost of oil, the real-world economy drops.

3. **Outdated Safety Features**

The bike lacks modern safety features such as **disc brakes (early models have drum brakes), ABS, traction control, or advanced suspension tuning**. Riding conditions, road surfaces, and weather can make it feel less stable than contemporary bikes.

4. **High Maintenance Requirements**

Two-stroke engines require **regular valve adjustments, piston ring checks, and carburetor tuning**. The **ignition coil (46018-047)** is a critical part that may wear out over time, and if it fails, it can be difficult to replace without sourcing a vintage or aftermarket part. The **clutch and transmission** also require more frequent attention than modern automatic or semi-automatic systems.

5. **Limited Comfort for Long Rides**

The **hard seat, minimal wind protection, and basic ergonomics** make the Big Horn uncomfortable for extended rides. Modern bikes offer better suspension, adjustable seats, and fairings for long-distance comfort.

6. **Resale Value is Low**

Unlike some classic bikes (e.g., Triumph Bonneville, Honda CB750), the Big Horn does not hold its value well. If you decide to sell it later, you may not recover much of your initial investment.

7. **Weather and Road Conditions Can Be Challenging**

Without modern suspension or tires, the bike can feel **bouncy on rough roads** and **unstable in rain or wind**. The lack of a windscreen means wind fatigue can set in quickly on highway rides.

8. **Parts Availability Can Be Inconsistent**

While some parts are still available, others (such as **specific carburetors, ignition components, or rare mechanical parts**) may require hunting through vintage dealers or eBay. Some components may need to be **remanufactured or sourced from other Japanese bikes** of the era.

---

### **Conclusion**

The **Kawasaki F7/F5/F9 Big Horn (1970 1978)** is a **fantastic choice for enthusiasts who appreciate classic design, simplicity, and a nostalgic riding experience**. It is well-suited for **casual riders, collectors, or those who enjoy the charm of vintage motorcycles** rather than high performance. However, it is **not ideal for daily commuting, highway riding, or riders seeking modern comfort and safety features**.

If you are looking for a **fun, low-maintenance bike for short trips, park riding, or as a conversation piece**, the Big Horn is an excellent purchase **especially if you enjoy tinkering with mechanics and restoring classic bikes**. However, if you need **reliability, power, or modern amenities**, you may want to consider a **modern cruiser, naked bike, or a well-maintained classic with a more robust engine**.

---

### **Recommendation**

You love **vintage motorcycles** and enjoy the **aesthetic and history** behind it.

You plan to **ride it occasionally** (not daily) and are okay with **some maintenance work**.

You have **access to a mechanic familiar with two-stroke engines** or are willing to learn.

You want a **lightweight, easy-to-handle bike** for **city or park riding**.

You are prepared to **invest time in restoration or maintenance** rather than expecting a "plug-and-play" experience.

You need a **reliable, high-mileage daily rider**.

You require **modern safety features (ABS, disc brakes, etc.)**.

You dislike **two-stroke engines** or are unwilling to deal with their maintenance quirks.

You plan to **ride long distances frequently** (comfort and wind protection are lacking).

You want a **high-resale-value or high-performance bike**.

The **Kawasaki Big Horn is a fantastic project bike or collector s item**, but it is **not a practical modern commuter or highway bike**. If you find one in **good condition with a well-maintained engine and transmission**, it can be a **rewarding and enjoyable** addition to your riding life **just be prepared for the extra care it requires**.
