Review HONDA Oem Flywheel Bolt fits SHADOW VT700C VT 700 1984–1987

The **Honda 90025-MK7-670** is a meticulously engineered flywheel bolt designed specifically for Honda s iconic VT700C Shadow and VT700C "Flyweight" models produced between 1984 and 1987. This high-performance component is a critical part of the engine s crankshaft assembly, ensuring precise alignment and optimal power transfer between the flywheel and the transmission. Crafted from premium-grade steel, this bolt is forged to Honda s exacting specifications, delivering exceptional durability and resistance to wear, vibration, and high-stress conditions that are inherent to high-revving, air-cooled V-twin engines. The **MK7-670** designation indicates its compatibility with the 700cc displacement variant of the VT700C, where reliability and performance are paramount. Whether you're restoring a classic Shadow to its original glory or upgrading an existing build, this bolt guarantees a secure, torque-tested fit, minimizing the risk of catastrophic failure and maintaining the engine s peak efficiency. Its design incorporates Honda s proprietary thread pattern and head geometry, ensuring a perfect match with the engine s crankshaft and flywheel interface, while its heat-treated surface enhances longevity under demanding riding conditions. For enthusiasts seeking authenticity and performance, this bolt is an indispensable, no-compromise replacement part that upholds the legacy of Honda s legendary VT700C lineup.

### **Pros and Cons of Buying a Honda VT700C Shadow (1984-1987) with the Specified Flywheel Bolt (90025-MK7-670)**

#### **Pros**

1. **Classic Design and Style** The VT700C Shadow is a cult classic with a distinctive, aggressive look that stands out on the road. Its angular fairing and bold styling make it instantly recognizable.

2. **Reliable Honda Engine** The 740cc parallel-twin engine is known for its durability and simplicity. With proper maintenance, many of these bikes last well beyond 100,000 miles.

3. **Modular and Upgradable** The VT700C has a strong aftermarket support, allowing for easy upgrades to suspension, exhaust, and performance parts. The engine is also relatively easy to work on compared to some modern bikes.

4. **Comfortable for Long Rides** The ergonomics are well-suited for cruising, with an upright riding position that reduces fatigue on extended trips.

5. **Affordable to Maintain** Parts are widely available, and labor costs are generally lower than on newer motorcycles. Basic maintenance (oil changes, chain adjustments) is straightforward.

6. **Great for Beginners and Experienced Riders** The VT700C is forgiving for new riders due to its manageable weight (around 450 lbs) and stable handling. Experienced riders appreciate its raw, unfiltered riding experience.

7. **Nostalgic Appeal** For enthusiasts of classic motorcycles, the VT700C holds a special place in the history of cruisers and adventure bikes, making it a fun and rewarding ride.

8. **Good Fuel Economy for Its Class** While not as efficient as modern bikes, it gets around 50-60 MPG, which is decent for a larger displacement bike of its era.

---

#### **Cons**

1. **Outdated Technology** The bike lacks modern safety features such as ABS, traction control, or advanced suspension systems. This makes it less safe in slippery conditions or high-speed maneuvers.

2. **Poor Fuel Injection Reliability** The early electronic fuel injection (EFI) system on the VT700C can be finicky, prone to failure, or require frequent tuning. Some riders opt for carbureted conversions for reliability.

3. **Weak Suspension** The stock suspension is basic and not designed for heavy riders or aggressive riding. Upgrading to modern aftermarket suspension is often necessary for comfort and control.

4. **Exhaust and Emissions Issues** The catalytic converter and exhaust system may not meet modern emissions standards, requiring modifications if the bike is ridden in areas with strict regulations.

5. **Limited Comfort for Long Distances** While the riding position is upright, the lack of wind protection and ergonomic refinements can make long rides less comfortable compared to modern adventure bikes.

6. **Rust and Corrosion Concerns** Many VT700Cs from this era suffer from rust, particularly in the frame, swingarm, and exhaust system. A thorough inspection is essential before purchase.

7. **High Maintenance Requirements** The EFI system, carburetors (if converted), and older components require more attention than modern bikes. Regular maintenance is a must to keep it running smoothly.

8. **Resale Value is Low** Unlike some classic bikes, the VT700C does not hold its value well due to its age and the availability of newer cruisers with similar styling.

9. **Noise and Vibration** The engine can be loud and vibrates noticeably at certain RPMs, which may not be ideal for daily riding in noise-restricted areas.

10. **Limited Modern Safety Features** Without ABS, a modern seat, or advanced braking systems, the bike is less safe in emergencies compared to contemporary motorcycles.

---

### **Ending Conclusion**

The **Honda VT700C Shadow (1984-1987)** is a fantastic choice for riders who appreciate classic design, reliability, and a raw riding experience. It is well-suited for enthusiasts who enjoy tinkering with their bikes, upgrading parts, and riding for fun rather than daily commuting. The bike s simplicity and aftermarket support make it a rewarding project, but it requires patience and maintenance to keep it in good condition.

However, if you prioritize modern safety features, comfort, and low maintenance, the VT700C may not be the best option. It is better suited for riders who:

- Enjoy the nostalgia and character of a classic bike.

- Are willing to invest time and money in upgrades and maintenance.

- Ride primarily for leisure, touring, or as a weekend project.

- Do not mind the lack of advanced safety technology.

For those who want a more modern cruiser or adventure bike with better safety and comfort, newer models from brands like Honda (Gold Wing, Africa Twin), Harley-Davidson, or Indian would be more appropriate.

### **Recommendation**

If you are **serious about restoring or maintaining the bike**, the VT700C is an excellent purchase for its historical significance and riding experience. However, **budget for potential repairs, especially if the bike has rust or EFI issues**. Consider starting with a **well-documented project bike** or one that has already undergone major restoration.

If you are **looking for a reliable, low-maintenance cruiser**, consider a newer Honda (e.g., Gold Wing, Shadow Spirit) or a well-maintained classic like a Honda CB750 or a restored Harley-Davidson.

Ultimately, the VT700C is a **great bike for the right rider** one who values tradition, craftsmanship, and the joy of riding a piece of motorcycle history.
