Review VESPA Nos 63-64 50 Smallframe Gearbox Gear Shim Two Slot 1st Oversize fits 1990

The **Vespa 79306 NOS (New Old Stock) gear shim set for the 63-64 50/90cc Small Frame gearbox** represents a meticulously preserved piece of classic Vespa engineering, designed to maintain the precise performance and reliability of one of the most iconic scooter models ever produced. This genuine, unopened shim set, sourced directly from the original manufacturer or an equally reputable aftermarket supplier, ensures that the gearbox whether in a 50cc or 90cc configuration operates with the same seamless engagement and minimal backlash that Vespa enthusiasts have come to expect. The shims, crafted from high-quality, precision-ground steel, are tailored to fit the specific dimensions of the Small Frame gearbox, which was first introduced in the early 1960s and became synonymous with the lightweight, nimble handling that defined the Vespa 50 and 90cc models of that era. Each shim in the set is designed to adjust the play between the gears and shafts, allowing for optimal meshing and reducing unnecessary wear, which is critical for maintaining the scooter s legendary smoothness and longevity. Whether restoring a vintage Vespa to its original glory or performing routine maintenance on a cherished collector s piece, this NOS shim set ensures that the gearbox functions with the same efficiency as it did when the scooter rolled off the production line in Piaggio s Italian factories. The inclusion of both the 50cc and 90cc shims in a single package makes this an exceptionally versatile and practical solution for owners of these models, accommodating the subtle differences in gear spacing and torque requirements between the two displacements. For those who appreciate the artistry of mechanical precision and the timeless appeal of Vespa s design, this shim set is not merely a functional component but a tangible link to the golden age of scooter craftsmanship.

Buying a **Vespa 79306 NOS (New Old Stock) from the 63-64 model range with a 50cc/90cc small frame and gearbox gear shim slot** can be an appealing option for collectors, restorers, or enthusiasts seeking an authentic classic. Below is a detailed breakdown of the pros and cons, followed by a conclusion and recommendation.

---

### **Pros**

1. **Authenticity and Rarity**

The 63-64 Vespa models are among the earliest production years of the iconic scooter, making them highly sought-after by collectors. A NOS unit ensures the original components are untouched, preserving historical value. The small frame (typically associated with the 50cc/90cc engines) is particularly rare, as later models shifted to larger frames.

2. **Original Condition and Potential for Restoration**

A NOS unit means you re starting with a fully original, unmodified scooter. This is ideal if you plan to restore it to factory specifications, as you won t need to source period-correct parts. The gear shim slot (a feature in early models for adjusting gear ratios) is a detail that appeals to purists and can add to the scooter s collectible appeal.

3. **Lower Mileage and Wear**

NOS scooters are often in excellent mechanical condition because they were either never used or stored properly. Early Vespas were built to last, and many of these models retain their original engines, transmissions, and frames with minimal wear. This can translate to fewer repairs and a longer lifespan if maintained properly.

4. **Investment Potential**

Early Vespas, especially NOS examples, tend to appreciate in value over time. The 63-64 models, in particular, are considered classics, and well-preserved units can fetch high prices at auctions or from specialized dealers. If treated as a long-term investment, this purchase could yield significant returns.

5. **Historical Significance**

Owning a piece of Vespa history is a unique experience. The 63-64 models represent the early evolution of the scooter, and their design reflects the post-war Italian engineering ethos. For enthusiasts, this historical connection is invaluable.

6. **Community and Enthusiast Appeal**

There is a dedicated community of Vespa collectors and restorers who value early models. Owning a NOS 63-64 scooter grants access to this community, where you can share knowledge, attend meets, and participate in restoration projects. This can be both socially rewarding and practically helpful for sourcing parts or advice.

7. **Simplicity of Design**

Early Vespas are mechanically simpler than modern versions, with fewer electronic components and more straightforward systems. This can make maintenance and repairs easier for those with mechanical skills, though it also means fewer modern conveniences.

---

### **Cons**

1. **High Cost**

NOS Vespas, especially early models like the 63-64, are expensive. The rarity, demand, and historical value drive up prices significantly. A fully original small-frame 50cc/90cc scooter from this era can cost anywhere from **$8,000 to $20,000 or more**, depending on condition, provenance, and market trends. This is a substantial investment compared to modern or later-model Vespas.

2. **Limited Availability of Parts**

While the scooter itself is NOS, finding replacement parts can be challenging. Original components may no longer be manufactured, and aftermarket parts may not fit perfectly or may be difficult to source. The gear shim slot, while a desirable feature, also means you ll need to carefully manage gear ratios if the original shims are worn or lost.

3. **Maintenance and Restoration Challenges**

Early Vespas were built with different materials and standards than modern vehicles. Rust, worn bearings, and outdated fuel systems (e.g., carburetures that may not work well with modern fuel) are common issues. Restoring a NOS scooter to perfect condition requires time, skill, and potentially expensive specialized labor.

4. **Lack of Modern Safety and Convenience Features**

Early Vespas lack modern amenities such as disc brakes, ABS, electric start, or even reliable lighting systems. The small frame and basic suspension may also make them less comfortable for taller riders or those accustomed to modern ergonomics. The gear shim slot, while a historical feature, adds complexity to gear adjustments and may not be as user-friendly as modern multi-speed systems.

5. **Storage and Preservation Requirements**

A NOS scooter requires careful storage to prevent deterioration. Exposure to moisture, temperature fluctuations, or improper handling can lead to rust, warped frames, or damaged components. If you re not prepared to invest in a climate-controlled storage solution or regular maintenance, the scooter s condition could degrade over time.

6. **Potential for Hidden Damage**

Even NOS scooters can have hidden issues. Rust in the frame, worn-out bearings, or a seized engine may not be immediately visible. A thorough inspection by a Vespa specialist is essential, and this can add to the overall cost. Some sellers may not disclose minor issues, leading to unexpected expenses.

7. **Resale Value Uncertainty**

While early Vespas appreciate in value, there s no guarantee. Market trends, economic conditions, and changes in collector preferences can affect resale prices. If you re not committed to long-term ownership, you may struggle to recoup your investment quickly.

8. **Operational Limitations**

Early Vespas are not built for high-speed or long-distance riding. The small frame, basic suspension, and older engine technology make them less suitable for modern commuting or highway use. They are best suited for short trips, show appearances, or leisurely rides in urban or scenic areas.

### **Conclusion**

Buying a **NOS Vespa 79306 from the 63-64 model range with a small frame and gear shim slot** is a significant decision that hinges on your priorities. If you value **authenticity, historical significance, and the potential for appreciation**, this purchase is a compelling investment. The scooter s rarity, original condition, and collectible status make it a prized possession for enthusiasts. However, if you re primarily seeking a **practical, modern, or low-maintenance vehicle**, the costs, challenges, and limitations of an early Vespa may outweigh the benefits.

The gear shim slot and small frame are charming historical details but also add complexity to maintenance. Your ability to commit time, effort, and resources to restoration and preservation will determine whether this scooter remains a joy to own or becomes a costly project.

### **Recommendation**

- You are a **collector or restorer** with a passion for early Vespas and the patience to work on a project scooter.

- You have **access to a Vespa specialist** for inspections and potential repairs.

- You are prepared to **store the scooter properly** and invest in its upkeep to maintain its value.

- You view this as a **long-term investment** rather than a short-term purchase.

- You enjoy the **historical and mechanical challenges** of owning a classic scooter.

- You need a **practical, daily-use vehicle** with modern safety and convenience features.

- You lack **mechanical skills or time** to dedicate to restoration and maintenance.

- You are **unprepared for the high upfront cost** and potential hidden expenses.

- You prioritize **low maintenance and reliability** over historical authenticity.

- You plan to **sell quickly** early Vespas are not liquid assets, and resale can be unpredictable.

**Final Suggestion:** If you re serious about this purchase, **inspect the scooter thoroughly with a trusted Vespa expert**, verify its provenance (e.g., original build date, service records), and consider starting with a **less expensive but still original model** (e.g., a 65-66) to test your commitment before investing in a rarer 63-64 unit. If you decide to proceed, treat it as both a **vehicle and a project**, and enjoy the journey of bringing this piece of history back to life.
