The Harley-Davidson Softail Dragster “Silverstone” by Thunderbike is a stunning example of how far custom craftsmanship can go when performance styling meets premium components.
Inspired by racing aesthetics and muscular dragster lines, this Softail build combines aggressive stance, high-end engineering, and a clean silver finish that fully lives up to its Silverstone name. It is not just a customized Harley – it is a statement of style and precision.
Race-inspired design with Grand Prix DNA
The first thing that stands out on the Silverstone Dragster is the Thunderbike GP-Style bodywork. The Front Fender Thunderbike GP-Style and Rear Fender Thunderbike GP-Style 260mm stretch the lines of the bike, emphasizing the massive rear wheel and low-slung silhouette.
The Chin Fairing Thunderbike GP-Style and Fuel Tank Thunderbike Custom GP-Style continue this flowing Grand Prix look, creating a cohesive racing-inspired design from front to back.
To match the sleek body parts, Thunderbike added the Headlamp Cap Thunderbike, enhancing the compact and aggressive front end. The result is a motorcycle with strong track DNA but unmistakable Harley-Davidson character.
Premium controls and cockpit details
Riding position and control components play a big part in the Dragster look. The Silverstone features the Thunderbike Clip-On Grand Prix bicolor handlebar, which places the rider in an aggressive, forward stance.
This is complemented by the Grip Set Thunderbike Base Satin and Toppers Thunderbike Base, adding subtle visual refinement.
For ultimate control, the bike is equipped with Levers Rebuffini hydraulic set with switch, offering precision feel and premium machining quality. Completing the ergonomics setup are the Forward Controls Thunderbike V-Tech, giving the Silverstone the stretched drag-style riding posture.
Custom intake, airbox, and engine accents
Thunderbike continued the Grand Prix theme into the engine area. A Thunderbike Airbox Baseplate works together with the Thunderbike Air Cleaner Airbox Kit and the stylish Airbox Cover Thunderbike Grand Prix. This combination not only enhances performance but also keeps the visual language consistent throughout the build.
The details matter – which is why parts like the Derby Cover Thunderbike Drilled and Ignition Cover Thunderbike New Custom were chosen. These touches reinforce the custom character and highlight the engine as the true heart of the Silverstone Dragster.
Single-sided swingarm and performance braking
One of the most eye-catching elements of the Silverstone build is the Thunderbike Single-Side Swingarm Kit 21”. This conversion exposes the custom rear wheel completely on one side, giving the bike a premium custom-show look while emphasizing the wide rear tire.
Braking performance is handled by a Brembo Radial Monoblock M4 brake caliper. This component comes directly from the high-performance motorcycle world and fits perfectly with the racing-inspired concept of the build.
Suspension, front end, and chassis components
To control power and improve handling, Thunderbike installed the Front End Thunderbike Radial Kit Grand Prix. This works together with the Triple Tree Thunderbike Grand Prix bicolor, providing stiffness, precision steering, and a distinctive visual signature.
The Seat Plate Thunderbike flows neatly into the rear section, completing the dynamic line of the dragster profile. Thunderbike’s design ensures that every component appears intentional and integrated, not simply added on.
Lighting and visual finishing touches
Attention to detail continues with carefully selected lighting elements such as Thunderbike Front Turn Signals and Thunderbike License Plate Lighting, keeping the rear minimalist and clean while remaining street-ready.
The exhaust note plays a major role in the overall experience, and the Thunderbike Exhaust delivers the deep sound and visual presence expected from a custom Harley-Davidson dragster. Custom Thunderbike Wheels complete the look, adding motion even when the bike is standing still.
A complete custom concept
The Harley-Davidson Softail Dragster “Silverstone” by Thunderbike is not just a list of aftermarket parts – it is a coherent concept motorcycle. Every modification supports the central idea: a drag-inspired, Grand Prix-styled Softail that blends elegance with aggression.
