Review YAMAHA Atm Kick Shaft Kickstarter Assembly Axle fits AT1 AT2 AT3 CT1 DT125 1970-76

The **Yamaha AT1, AT2, AT3, ATM, CT1, and DT125** models from the early 1970s specifically the **1970 1976 era** represent a legendary era in motorcycle engineering, and the **Yamaha 315-15660-01-00** part number corresponds to a critical component: the **kickshaft assembly**, including the **kickstarter axle, kickshaft, and associated kickstarter mechanism**. This meticulously crafted part is a testament to Yamaha s precision manufacturing during a time when reliability and performance were paramount in the world of adventure and touring bikes. Designed for the **AT-series (AT1, AT2, AT3, ATM)** and the **CT1 and DT125** models, this kickshaft assembly plays a vital role in the bike s starting mechanism, ensuring smooth and efficient operation even in the most demanding conditions.

The **kickshaft** itself is forged from high-quality steel, engineered to withstand the repeated stress of repeated kickstarts without warping or failing. Its robust construction ensures durability, a hallmark of Yamaha s engineering philosophy from the era, where parts were built to last for decades with proper maintenance. The **kickstarter axle** is precision-machined to fit seamlessly within the engine s crankcase, allowing for minimal play while maintaining smooth operation. This axle supports the kickstarter lever, which, when engaged, transmits force through the kickshaft to crank the engine over, initiating combustion and bringing the bike to life.

One of the standout features of this component is its **interchangeability** across multiple models, making it a versatile and sought-after part for restorers and enthusiasts working on these classic bikes. The **ATM (Adventure Touring Model)**, in particular, benefited from this kickshaft assembly s reliability, as it was designed for long-distance travel where dependability was non-negotiable. Similarly, the **CT1 and DT125** smaller, more agile models relied on this same high-quality kickstarter mechanism to deliver consistent performance, whether on urban commutes or off-road adventures.

Beyond its mechanical function, this kickshaft assembly reflects the **aesthetic and functional evolution** of Yamaha s early designs. The **1970s-era AT bikes** were pioneers in the adventure touring segment, blending the ruggedness of off-road capability with the comfort and practicality of long-distance travel. The kickstarter mechanism, though seemingly simple, was a crucial element in ensuring that riders could depend on their machines in remote locations where electric starters were impractical. The **Yamaha 315-15660-01-00** part number encapsulates this reliability, offering a direct connection to the era s innovation and craftsmanship.

For collectors, restorers, and riders seeking to preserve the integrity of their vintage Yamaha, this kickshaft assembly is an essential component. Its **authentic fit and finish** ensure that the bike operates as it was intended, with the same smoothness and efficiency that Yamaha engineers strove for in the late 1960s and early 1970s. Whether installed in an **AT3** for a cross-country journey or a **DT125** for urban exploration, this part guarantees that the bike s starting mechanism remains as dependable as the day it left the factory. With its **timeless design and uncompromising quality**, the Yamaha 315-15660-01-00 kickshaft assembly stands as a perfect example of the brand s legacy in motorcycle engineering.

---

### **Cons**

1. **Age-Related Wear and Tear**

- Many 1970s AT series bikes have high mileage, which can lead to worn-out components, including the **kick shaft and axle**. Rust, bent shafts, or seized mechanisms are common issues.

- The **DT125 kickstarter axle** may require replacement if it is cracked, bent, or corroded, adding to maintenance costs.

2. **Limited Power and Speed**

- The 125cc engine produces only about **8 10 horsepower**, making these bikes slow by modern standards. They are not suitable for highway riding or fast-paced commuting.

- The **kickstarter system** adds slight resistance compared to electric starters, which can be tedious on long rides.

3. **Comfort and Ergonomics**

- The bikes are designed for off-road use, with a narrow seat and minimal wind protection. Long rides on pavement can be uncomfortable.

6. **Modification Limitations**

- Upgrading performance (e.g., bigger carburetors, exhaust) is possible but limited by the stock engine s design. The **kickstarter system** can also interfere with some modifications.

- Suspension and braking upgrades are common but may not match modern safety standards.

7. **Resale Value**

- While well-maintained examples hold value, most AT series bikes depreciate quickly. They are not typically seen as long-term investments.

8. **Weather and Storage Challenges**

- The bikes are not weatherproof, and rust is a common issue. Proper storage (indoors or with rust inhibitors) is essential to preserve the **kickstarter axle and other components**.
