### **Pros and Cons of buying a Yamaha TT350 (1986-87) with the Specified Parts**

#### **Pros**

1. **Classic and Reliable Design** The Yamaha TT350 is a well-regarded classic trail bike known for its durability and off-road capability. Its simple yet robust design makes it a favorite among riders who appreciate no-frills, functional motorcycles.

2. **Proven Engine and Performance** The TT350 features a 347cc air-cooled single-cylinder engine, which is known for its smooth power delivery and reliability. It produces around 25-30 horsepower, making it suitable for light trail riding, commuting, and even some light off-road use.

3. **Lightweight and Maneuverable** The TT350 is relatively light (around 220-230 lbs), which makes it easy to handle, especially for riders of average size. Its compact size also makes it ideal for parking and navigating tight trails.

4. **Simple Maintenance** The bike s straightforward mechanical design means that repairs and maintenance are generally easier and less expensive than on modern bikes. Many parts are still available through aftermarket suppliers.

5. **Historical and Collectible Value** If you appreciate classic motorcycles, the TT350 holds some nostalgia and could appreciate in value over time, especially if restored to original condition.

6. **Affordability** Compared to modern bikes, the TT350 is inexpensive to purchase, especially if you find a well-maintained example. Fuel and maintenance costs are also lower than on modern high-performance bikes.

7. **Triple Clamp and Stem Upgrades** The specified parts (1LN-23435-01-98 triple clamp and top/bottom stem bearing) are genuine Yamaha components designed to improve handling and reduce play in the steering. Upgrading these parts can enhance ride quality and longevity.

#### **Cons**

1. **Outdated Technology** The TT350 lacks modern conveniences like disc brakes (it typically comes with drum brakes), electronic fuel injection, or advanced suspension systems. This can make it less safe and less comfortable on rough roads or high-speed riding.

2. **Poor Fuel Efficiency** The air-cooled single-cylinder engine is not fuel-efficient by today s standards, consuming around 40-50 mpg in ideal conditions. This can add up over long distances.

3. **Limited Power and Speed** The TT350 s power output is modest, making it unsuitable for highway riding or aggressive off-roading. It struggles in high winds and on steep climbs.

4. **Rust and Wear Issues** Many older TT350s suffer from rust, especially in the frame, suspension, and exhaust. A thorough inspection is crucial before purchasing to avoid hidden repair costs.

5. **Parts Availability** While some parts are still available, others may require sourcing from specialty suppliers or eBay. The triple clamp and stem bearing you mentioned are genuine Yamaha parts, but finding exact matches for other components (e.g., suspension, brakes) can be challenging.

6. **Safety Concerns** The lack of modern safety features (e.g., ABS, traction control, or advanced braking systems) increases the risk of accidents, especially on wet or uneven terrain.

7. **Resale Value** Unlike some classic bikes, the TT350 does not hold significant resale value unless it is in pristine condition or part of a collection.

8. **Comfort Limitations** The ergonomics and seating position are not as refined as modern bikes, which can lead to discomfort on longer rides. The suspension is basic and may not absorb bumps well.

9. **Environmental Regulations** Some regions have restrictions on older bikes due to emissions standards. While the TT350 likely meets basic requirements, you may face challenges registering it in areas with strict pollution laws.

10. **Project Bike Potential** If the bike is not in good condition, restoring it to running order can be time-consuming and costly. This may not be ideal for riders who want a "ready-to-ride" bike.

### **Conclusion**

The Yamaha TT350 (1986-87) with the specified triple clamp and stem bearing upgrades is a **great choice for riders who prioritize simplicity, reliability, and affordability** over modern comfort and performance. It excels as a **light trail bike, commuter, or project bike** for those willing to accept its limitations. The upgrades you ve selected will improve handling and durability, making it a more enjoyable and long-lasting ride.

However, if you require **highway capability, modern safety features, or off-road performance**, the TT350 may fall short. It is also not ideal for riders who expect a comfortable, high-speed experience.

### **Recommendation**

- **Buy it if:** You enjoy classic bikes, plan to use it for light trail riding or commuting, and are prepared to maintain it. The triple clamp and stem bearing upgrades are wise investments for longevity.

- **Avoid it if:** You need a bike for highway riding, expect to ride in harsh conditions, or want modern safety and comfort features.

- **Consider alternatives:** If you like the TT350 s simplicity but want better performance, look at modern trail bikes like the **Yamaha TW200** or **Honda XL650V**. If you re set on a classic, a **Honda CT125** or **Kawasaki KL500** might offer a better balance of reliability and usability.

Ultimately, the TT350 is a **fantastic bike for the right rider** one who appreciates its charm and is willing to work with its limitations. If you re buying it for its historical value or as a fun, low-maintenance ride, it s a solid purchase. If you need a bike for serious riding, explore more modern options.
