Introduction
The Rail Star is a striking custom built from a donor Harley-Davidson Street Bob by Lithuanian workshop Killer Custom. What immediately sets this build apart is an exceptional paint finish that gives the tank a honeycomb texture reminiscent of luxurious snakeskin. While the underlying frame, geometry and Milwaukee‑Eight engine remain, the Rail Star replaces the Street Bob's restrained cruiser look with a sharper, urban-focused attitude.
Design and Visual Upgrades
Bold paint and bodywork
Most custom motorcycles live or die by their paint, and the Rail Star proves that a world-class finish can transform a bike. The majority of the bodywork is deep black, but the centerpiece is the fuel tank’s honeycomb motif that, from a distance, reads like soft, high-end snakeskin. Blacked-out components are contrasted with selective red accents and pristine white wheels to create deliberate visual highlights. Additional non-factory body parts — such as a chin spoiler and a headlight cowl — give the bike a layered, aggressive silhouette more aligned with urban street styling than the original cruiser aesthetic.
Controls and ergonomics
The handlebars have been repositioned slightly, and custom grips were fitted. These changes alter the rider’s stance and control inputs, contributing to the Rail Star’s more assertive presence and ride feel compared with a stock Street Bob.

Performance and Mechanical Changes
Engine and intake
The stock Milwaukee‑Eight V‑twin from the Street Bob remains in the frame, and there’s no evidence of internal engine rework. Still, visible bolt‑on upgrades are aimed at improving breathing and exhaust flow: an open cone air intake and shortened mufflers from a custom exhaust system are fitted to increase intake efficiency and add a more aggressive note.
Brakes and handling
Observers noted subtle signs that the braking system has been addressed during the build — likely upgraded components or adjusted setup for a tighter, more responsive ride. Suspension and chassis geometry appear largely retained, preserving the Street Bob’s familiar road manners while the visual mods shift its character toward sportier urban use.
Vehicle Specifications (Build Summary)
- Donor: Harley-Davidson Street Bob (frame, geometry, Milwaukee‑Eight engine retained) - Engine: Milwaukee‑Eight V‑twin (factory-installed; stock output likely unchanged) - Major exterior mods: custom honeycomb tank paint, chin spoiler, headlight cowl, white wheels, blacked-out components, red accents - Performance mods: open cone air intake, custom grips/controls, shortened custom exhaust, possible brake upgrades - Estimated extras cost: approx. $5,800 (parts and visible custom items) - Base bike price (current): $15,999 (as reported for the model used)

Market Positioning and Build Cost
The Rail Star sits in the niche of boutique custom cruisers that blend factory reliability with bespoke styling. Its identity is built around standout visuals and tasteful bolt-on performance parts rather than a complete drivetrain overhaul. With roughly $5,800 in documented extras plus the base Street Bob price and additional labor and paint costs, owners contemplating a similar conversion should budget beyond the parts list for paint, fabrication and skilled shop hours — the total can vary widely depending on finish complexity and labor rates.
Comparison: Rail Star vs. Stock Street Bob
Compared with the stock Street Bob, the Rail Star trades the factory’s clean, classic cruiser look for a more aggressive, street‑centric persona. Key differences include bespoke paint, extra bodywork (chin spoiler and headlight cowl), white wheels, and targeted performance parts like the open intake and shorter mufflers. Mechanically the bikes remain close, preserving the trusted Milwaukee‑Eight powerplant and the donor frame’s geometry.
Conclusion
The Rail Star is a compelling example of how strategic cosmetic and bolt-on mechanical changes can reinvent a motorcycle. For riders who value show‑stopping aesthetics paired with subtle performance tweaks, this Street Bob conversion demonstrates how a high-caliber paint job and a handful of focused upgrades produce a bike that’s unmistakably custom without sacrificing the reliability of the original Harley-Davidson platform.
