NICECNC Rear Brake Reservoir Cap, Aluminum
Product description
Sportster owners looking to replace a rear brake reservoir cap and add a darker accent to the bike may find this NICECNC part relevant. It is made from 6061 aluminum and finished in black.
It is listed as a direct replacement for part 41700095. The stated fitment covers several Sportster models, but the exact year and model still matter.
This is a component-level change, not a brake-system upgrade. Its appeal is the replacement fit and a more distinctive finish.
Key specifications
The cap is CNC-machined from 6061 aluminum alloy and has a black surface finish. NICECNC describes it as a direct replacement for the stock rear brake reservoir cap, using factory mounting points without modifications. The listed replacement number is 41700095.
The fitment information names the Iron 1200 XL1200NS for 2018–2021 and Iron 883 XL883N for 2014–2020. It also lists Sportster models including the Forty Eight XL1200X, Seventy Two XL1200V, and Sportster 883 XL883L, with a broader 2014–2021 range stated for the compatible models. Since those details do not establish that every year of every named model fits, check the exact application before ordering. The black finish and aluminum construction describe the part, they do not confirm fit by themselves.
Who it’s for
This cap is aimed at Sportster riders replacing a worn or stock-looking reservoir cover, or adding a small black accent without changing more of the motorcycle. The visual effect is deliberately modest: it updates one visible piece rather than transforming the whole bike.
A solid pick if you already know your motorcycle matches the listed application and want a metal replacement cap with a CNC-machined finish. Not the best choice if you need a part that fits any Sportster, or if your goal is to change braking behavior, the product information describes a cap, not a performance component. On the spec sheet, its main distinction is material and finish, so riders choosing strictly by function may have little reason to move beyond a suitable stock-style replacement.
Everyday use
In routine use, this is a small part you may notice while cleaning the bike or checking around the rear brake reservoir. It replaces the cap itself, so the practical decision is whether the stated fitment and black aluminum look suit your motorcycle—not whether it adds a new braking function.
Compared with a broader styling project or a brake-system modification, swapping a reservoir cap is a narrower change. That can make sense when you want to refresh one detail and keep the rest of the setup as it is. The product description claims a corrosion-resistant finish and an easy, no-modification installation, but it does not provide further installation steps or independent durability details. Match the application carefully rather than treating the direct-replacement wording as universal compatibility.
Practical doubts
Does it replace the stock cap?
It is described as a direct replacement for the stock rear brake reservoir cap and for part 41700095. Confirm that number and the bike’s model and year match your application.
Which Sportster models are named?
The listing names the Iron 1200 XL1200NS, Iron 883 XL883N, Forty Eight XL1200X, Seventy Two XL1200V, and Sportster 883 XL883L. Year coverage is not equally detailed for every model in the supplied information.
Does it improve braking?
No braking-performance change is specified. The stated purpose is replacing the reservoir cap and changing its appearance, so choose a different type of component if your goal is a functional brake-system change.
Is it worth it?
It makes sense when the fitment checks out and you want a black 6061 aluminum replacement for a specific Sportster, especially if the existing cap looks out of place or needs replacing. The CNC-machined construction and black finish give the part a more tailored appearance than simply keeping the stock cap, while the installation is presented as a direct swap.
Skip it if you cannot confirm the exact year and model, or if you expect a noticeable mechanical upgrade. The available information supports a focused replacement and styling decision, it does not establish broader compatibility or a change in braking performance.
