OSAN Motorcycle Headlight Mount Brackets 35mm-43mm Fork Ear for Chopper Café Racer (Black)
Product description
What it is and who it’s for
OSAN’s universal headlight mount brackets are designed for motorcycles with 35–43mm diameter fork tubes. They’re a practical fit for Harley, Kawasaki, Suzuki, Yamaha and custom builds such as Chopper, Bobber, and Café racer. The goal is straightforward: give you a solid, adjustable perch for the headlight without fuss.
What stands out in use

On the page, the brackets are described as made from CNC machined billet aluminium, which helps with durability in variable weather. The manufacturer highlights weatherproof, water-resistant and rust-free properties, which matters if you ride in damp or salty conditions. The mounting holes and overall geometry are set up to accommodate a broad range of fork configurations, and the central measurement is approximate 115mm from the fork centre to the furthest hole. The headlight mounting hole is 9.7mm in diameter, a detail that helps you gauge compatibility with standard lamps.
What to know before buying
The brackets are fully adjustable to fit 35–43mm fork tubes, and they promise a straightforward installation with an adjustable up/down lamp angle. There are no instructions included in the description, so you may rely on the hardware and built-in adjustability rather than a step-by-step guide. If you’re checking compatibility, note the size notes and verify the fork diameter on your bike before purchasing.



How to use them in practice
If your bike uses a conventional round headlight with a 9.7mm mounting hole, these brackets can offer a practical mounting solution, especially on vintage-inspired builds where clean lines matter. The ability to tilt the lamp up or down lets you dial in beam pattern for street riding or daytime visibility. It’s a simple, utilitarian approach rather than a feature-heavy upgrade.
Pros and cons in context

Pros: robust-looking aluminium construction, corrosion resistance claims, wide fork compatibility (35–43mm), adjustable tilt, and a compact mounting footprint that suits classic and custom bikes. Cons: no included installation guide, and the description does not provide weight or exact finish details beyond “Black”. The product is presented as universal rather than engineered for a specific model, which means you’ll want to double-check your frame and lamp compatibility before buying.
Who it’s for
It makes sense for riders building or upgrading a custom bike where the headlight mounting needs to be versatile across common fork sizes and where a clean, unobtrusive mounting solution is valued. If you prioritise durability in harsh weather and a straightforward mounting setup, these brackets could fit your project.



When it’s worth considering
Consider these brackets if your fork tubes are within the 35–43mm range and you’re aiming for a simple mount with adjustable aiming. They’re particularly relevant for choppers or cafe racers where the aesthetic is a priority and a dedicated, bespoke mount isn’t required.
When to look elsewhere

If your fork diameter sits outside 35–43mm, or if you need a detailed installation guide, a lighter-weight or more feature-rich mounting system, or specific model optimisations, you might want to compare with purpose-built options rather than universal brackets.
What to review before buying
- Confirm fork tube diameter 35–43mm for your bike
- Check that your headlight mounting hole is compatible with a 9.7mm bolt
- Consider whether you need a full hardware kit beyond the brackets and bolts stated
- Think about the finish and weight, which aren’t fully detailed in the description

Is it worth it?
You’ll like it if you want a robust, adjustable mounting solution that works across a range of retro and custom bikes and you’re not chasing a model-specific bracket. It may not be the best option if you require precise model-specific engineering, detailed installation guidance, or if your fork diameter falls outside the stated range.
FAQ
Q: Will this fit forks outside 35–43mm? A: The brackets are described as adjustable within 35–43mm, so they’re not advertised for forks outside this range. Q: Is the finish resistant to rust and weather? A: The description claims weatherproof and rust-free properties, but no independent testing is provided. Q: Do I get an installation guide? A: No instruction is mentioned, installation relies on the adjustable design and included bolts.
