When customizing your Harley-Davidson Street Glide, one of the most popular upgrades is installing a 21-inch front wheel. However, this modification can raise questions about compatibility with the stock fender. This article will explore the factors to consider and provide practical recommendations for fitting a 21-inch wheel on your Street Glide with a stock fender.

Factors Affecting Compatibility

1. Rim Width and Tire Size:

A 21-inch tire requires a wider rim, typically 3.5 inches or wider, to ensure safe and proper fitment. Additionally, the tire size plays a role; a wider tire may necessitate a wider rim and/or fender modifications.

2. Front Suspension:

The length and angle of the front forks influence clearance between the tire and fender. Longer forks or a rake angle that angles the forks forward can provide more space for a 21-inch wheel.

3. Fender Clearance:

Stock fenders may not have sufficient clearance for a 21-inch wheel. Cutting or trimming the fender may be necessary to increase space and prevent interference.

Recommended Approaches

1. Manufacturer Specifications:

Consult the Harley-Davidson manufacturer’s guidelines for your specific Street Glide model. They provide recommended wheel sizes and compatibility information.

2. Physical Measurement:

Measure the current tire and fender clearance to determine if there is enough space to accommodate a 21-inch wheel. Ensure proper clearance for both straight-line riding and suspension compression.

3. Expert Advice:

Seek recommendations from experienced mechanics or Harley-Davidson dealerships. They can provide specific advice based on your bike’s make and model, considering factors such as suspension setup and desired tire size.

4. Test Fitment:

If possible, obtain a 21-inch wheel and tire and perform a test fitment before making any permanent modifications. This allows you to assess clearance and make any necessary adjustments.

Considerations

• Using a 21-inch wheel on a motorcycle designed for a smaller wheel may affect handling and performance characteristics.
• Installing a wider tire may require adjustments to the front brake system to ensure proper engagement.
• Modifications to the fender can compromise its structural integrity and weather resistance.

Case Study: Customizing a Street Glide with a 21-Inch Wheel and Stock Fender

For my 2017 Street Glide Special, I initially opted to keep the stock front fender when upgrading to a 21-inch wheel. However, to enhance the aesthetic appeal, I decided to purchase a custom vinyl wrap from HOGWORKZ®. The wrap arrived this past Friday and I’m eagerly anticipating its installation.

The HOGWORKZ® 21-inch wrapped front fender is specifically designed for my Street Glide model. It’s gefertigt from high-quality steel and provides a sleek and color-matched upgrade to replace the bulky stock fender. The wrap features a CVO Maple paint finish that perfectly matches the bike’s existing color scheme.

The cost of the wrap was approximately $600, which includes professional installation. While it’s a significant investment, I believe it will significantly enhance the appearance of my Street Glide. If I’m not satisfied with the wrap, I can revert to the stock fender without any permanent modifications.

I’ll be posting pictures of the modified fender once it’s installed. Stay tuned for updates on the transformation of my Street Glide with a 21-inch front wheel and custom-wrapped stock fender.
