Custom Motorcycle Fenders for USD Forks

A great motorcycle fender is more than just protection from road debris, it defines the look and feel of your ride. At Raw Metal Racers, we design and build custom motorcycle fenders that strike the perfect balance between form, function, and craftsmanship.

Why upgrade to a USD fork setup?

Upgrading your motorcycle with a modern Upside Down Fork (USD fork) is one of the most popular modifications in the custom scene. USD forks offer greater stiffness, sharper steering, and more precise handling, along with a modern, aggressive appearance that transforms the front end of any cafe racer, scrambler, street tracker or chopper. Popular swaps include complete front ends from sportbikes such as the Suzuki GSX-R, Hayabusa, Yamaha YZF-R1 and R6, Ducati Monster, BMW S1000RR, and BMW R nineT.

The problem with stock fenders

Most stock motorcycle fenders from donor bikes are bulky, oversized, and visually off-balance on a clean custom build. That’s where we come in. We produce aftermarket motorcycle fenders that are minimalist, lightweight, and tailored to match the lines of your bike.

Each of our custom fender for motorcycle builds is made from either:

• High-quality ABS plastic – lightweight and paint-ready

• Aluminium – raw metal finish, timeless appeal

Both options are ideal for customising the front end of your bike without compromise.

Custom fender mounting for USD Forks

Each custom motorcycle fender is made in-house in the Netherlands. Our precision laser-cut 3 mm stainless steel brackets are engineered to fit your specific USD fork with millimeter accuracy. The brackets flow seamlessly with the fork legs for a factory quality fit, while the fenders themselves are finished to the highest standards for durability and style.

Watch the video below to see how our custom fenders are handcrafted in our workshop in the Netherlands.

Custom rear motorcycle fender options

We also offer custom rear motorcycle fenders, built to match the style of your build whether you want a scrambler-style tail or a full-length café racer rear. As with our front fenders, our rear fenders are designed with both aesthetics and durability in mind.

Fenders for factory USD fork bikes

We also produce custom fenders for motorcycles for bikes that already come with USD forks from the factory. If you own a Triumph Thruxton, Bonneville, T100, Street Twin, Street Cup, Street Scrambler, or Speed 400, we offer beautifully styled fenders that enhance your bike’s look, built to perfection.

Frequently Asked Questions

1. What’s the advantage of custom motorcycle fenders over stock fenders?

Stock fenders are often bulky and generic. A custom motorcycle fender improves aesthetics, reduces weight, and enhances performance while maintaining the right level of protection for your ride. A lighter front fender also reduces unsprung weight, which helps the suspension react faster to bumps and improves handling. This makes the bike more agile, easier to steer, and slightly better at braking and accelerating.

2. Are Raw Metal Racers fenders universal or model-specific?

We offer both universal and model-specific fenders. Universal options work with various bikes, while our precision-fit fenders are designed for specific brands like BMW, Honda, Suzuki, Harley-Davidson, Yamaha, and Kawasaki.

3. What materials are used for custom fenders?

We use stainless steel, aluminum, and thermoplastics, depending on the design and intended durability. Stainless steel offers maximum strength and corrosion resistance, while aluminum provides a lightweight part with a sleek finish.

4. Can I install a custom fender myself, or do I need professional help?

Most fenders are bolt-on or require minimal modification, making them a great DIY upgrade. However, some universal fenders may require minor fabrication or adjustments for the perfect fit.

5. Do custom fenders improve handling or just change the look?

A properly designed fender can reduce drag, minimize excess weight, and improve aerodynamics, reduce unsprung weight, contributing to a smoother ride while also refining the bike’s profile. 

6. What styles of custom fenders do you offer?

We design classic shorty fenders, bobber-style fenders, high-clearance scrambler fenders, each crafted for both functionality and aesthetics.
