Bikers Choice Raw Fatbob Rear Fender Left Chain Cut Big Twin Custom

If you’re after that classic Fat Bob® look — low, wide, and unapologetically muscular — this rear fender is where most custom builds start. The generous profile creates a beefy rear stance that fills the wheel well and gives your Big Twin a planted, custom appearance. Because it’s supplied in raw steel, this fender is a blank canvas: strip it, metal-finish it, seam-weld it, smooth it, and paint it however you like. The left-side chain cutaway is already formed into the panel, saving you the headache of later modifications on chain-drive setups. This isn’t a flashy, chrome-coated display piece — it’s honest, heavy-duty sheetmetal made for riders and builders who prefer to craft their own finish and ride what they built. Whether you’re fabricating a cafe-inspired bobber, a slammed custom cruiser, or a show bike with subtle details, this fender provides the bold starting point.

Key features & benefits

Authentic Fat Bob® profile: Wide, tapered shape gives a classic custom look and fills larger rear tires for an aggressive stance.
Raw-steel construction: Supplied unfinished so builders can weld, metal-work, and finish to taste — ideal for paint, powder coat, or bare-metal patina.
Left chain cutaway: Pre-cut clearance on the left side saves fabrication time and ensures proper fit for chain-driven Big Twin applications.
Built for custom fitment: Designed specifically for Big Twin custom applications — gives ample material and shape for trimming, mounting, and custom bracketry.
Solid, serviceable dimensions: Large surface area provides broad coverage and the visual impact most custom bikes aim for.

Specifications

Part Number: BKC492770
Description: Biker’s Choice Raw Fat Bob® Rear Fender — Left Chain Cut — Big Twin Custom
Finish: Raw steel (unpainted, unfinished)
Dimensions: 38 in. L x 6-3/4 in. W x 5-1/2 in. D (approximate external dimensions)
Orientation: Left chain cutaway for chain clearance

Fitment & intended use

Made for Big Twin custom applications, this fender is a universal custom part — not a bolt-on for every factory configuration. It is intended for custom fabricators and experienced home builders who will adapt mounting points, tab brackets, or struts to suit their frame, swingarm, and tire combination. Use cases:

Custom Big Twin bobbers and choppers
Show bikes requiring a wide, vintage Fat Bob® silhouette
Restoration projects where the builder wants to replace a damaged OEM panel with a custom blank
Fabrication practice pieces for metalworkers building custom rear ends

Installation & prep notes

Because the fender ships raw, expect to perform metal prep: clean, de-scale, prime, and seam-weld any mounting tabs.
Test-fit before finishing: clamp the fender in place, check chain clearance, and mark welding/mounting positions. The pre-cut left chain area is helpful but may still require minor trimming depending on your sprocket and chainline.
If you plan to run a large tire or tuck the fender tightly, check tire clearance with the wheel at full lock and under suspension sag.
For paint prep: use etch primer on bare steel, then a high-build primer to fill small imperfections before final color or powder coat.
If you want a rusted/patina look, consider sealing the surface after achieving the desired patina to stop further corrosion.

Why choose this fender?

This Biker’s Choice piece hits the sweet spot for builders — it has the iconic Fat Bob® geometry, is made from workable raw steel, and includes a practical left chain cutout so you’re not reinventing the shape. Rather than a one-size, one-finish bolt-on, it gives you the freedom to create something truly custom while starting from a strong, thoughtfully formed blank. If you’re building a Big Twin and want the classic Fat Bob® rear look with the freedom to finish it your way, Part BKC492770 is a practical and inspirational starting point. Add this raw rear fender to your cart and start shaping the rear end of your next custom—because the best bikes don’t come off an assembly line, they come from hands that care.
