The **Yamaha 90387-20177 DT1/RT1 Enduro Shaft Collar** is a precision-engineered, high-performance component designed exclusively for Yamaha s DT1 and RT1 enduro motorcycles, ensuring optimal power transfer and drivetrain reliability in rugged off-road conditions. Crafted from durable, heat-treated steel, this shaft collar is built to withstand the demanding stresses of aggressive riding, including sharp cornering, heavy braking, and prolonged use on uneven terrain. Its robust construction minimizes flex and vibration, which helps maintain drivetrain alignment and reduces wear on the clutch, transmission, and rear axle components.

Additionally, the collar s precise engineering allows for easy installation and removal, making routine maintenance and adjustments straightforward without the need for specialized tools. Whether tackling rocky trails, steep inclines, or loose, sandy surfaces, this shaft collar is a vital yet often overlooked part that contributes to the longevity and performance of Yamaha s legendary enduro bikes, ensuring riders can push their limits with confidence in the reliability of their drivetrain.

### **Pros and Cons of buying a Yamaha DT1/RT1 Enduro Shaft Collar (Part #90387-20177)**

1. **OEM Replacement Part** This is an original Yamaha shaft collar, meaning it is designed to fit perfectly with the DT1 and RT1 models without modifications. It ensures proper alignment and function, reducing the risk of premature wear or failure.

2. **Durability and Reliability** Yamaha components are known for their quality and longevity, especially in off-road applications where durability is critical. A genuine shaft collar is built to withstand the stresses of enduro riding.

3. **Compatibility with Aftermarket Upgrades** Since it is an OEM part, it can be easily integrated with other aftermarket components (such as aftermarket shafts, clutches, or flywheels) without compatibility issues.

4. **Easier Maintenance and Replacement** Being a standard part, it is widely available from Yamaha dealers and authorized sellers, making repairs or replacements straightforward. Mechanics familiar with Yamaha bikes will be able to install it quickly.

5. **Prevents Drivetrain Damage** A failing or improperly fitted shaft collar can cause excessive play in the drivetrain, leading to chain or sprocket wear. This part helps maintain proper tension and alignment, reducing the risk of costly damage.

6. **Cost-Effective for Long-Term Use** While the upfront cost may be higher than some aftermarket alternatives, its reliability and longevity make it a cost-effective choice over time, especially for serious riders who prioritize performance and durability.

7. **Warranty Coverage** Purchasing from an authorized Yamaha dealer ensures that the part may still be covered under warranty (if applicable), providing peace of mind against defects.

1. **Higher Upfront Cost** Compared to some aftermarket or generic shaft collars, the OEM part from Yamaha is typically more expensive. This may be a deterrent for riders on a tight budget or those who prefer cheaper alternatives.

2. **Limited Customization** Unlike aftermarket parts, this is a stock component with no modifications available. Riders looking for performance-enhancing features (such as lighter weight or reinforced materials) may need to explore other options.

3. **Potential Overkill for Light Use** If the bike is used infrequently or primarily for casual riding, the premium quality of the OEM part may not be necessary. In such cases, a budget-friendly aftermarket alternative could suffice.

4. **Availability Dependence on Dealers** While widely available, some Yamaha dealers may not stock this specific part, requiring an order or wait time. Online retailers can help, but shipping costs may apply.

5. **No Significant Performance Gains** Unlike components such as exhaust systems or suspension forks, a shaft collar does not directly improve performance. Its value lies in reliability and drivetrain protection rather than speed or handling upgrades.
