This build features a stunning setup starting with a Rick’s Motorcycles Super Steve 3.5×21″ front wheel paired with an ultra-wide 10.5×18″ rear wheel, giving the bike its unmistakable presence on the ground. The SJP front fork and Bad Land’s handcrafted one-off handlebar, front fender, swingarm, and rear fender complete a flawlessly balanced silhouette.

A beautifully shaped Parker gas tank flows perfectly into a VG Motorcycles / Bad Land frame, while the BSL exhaust adds both visual punch and a deep, powerful note.

Performance is driven by a beastly S&S 2000cc engine matched with an H-D 5-speed transmission and a BDL belt drive kit, delivering raw, reliable power. Stopping performance comes from RST brake calipers, and the bike controls are upgraded with REBUNNIFI components for precision riding.

Finished with a meticulous Keen Edge paint job and a tailored Clione Speed seat, the Tiger stands as a perfect blend of engineering, artistry, and attitude.

A true showstopper — bold, muscular, and unmistakably Bad Land.

The Chopper’s wide 240mm rear tire also stands out and complements the design of the bike perfectly. The pair of wheels adorning the bike are given a unique violet color that makes them pop and dazzles in the sunlight.

One of the most impressive touches, however, is the completely handmade black double exhaust that gives the bike a beastly roar. All of these design elements combine to create a bike that oozes style and sophistication.

The bike features low and elongated structure, highlighting its unique design flawlessly. It has no visible rear protector, leaving the wide rear tire and its features on full display for all to see and admire.

The motorcycle’s finish is outstanding and adds an extra layer of sophistication to the bike. The combination of all of these elements makes this bike unforgettable and something that will undoubtedly stand out on the road.

In conclusion

The customized Chopper-style bike by Tarso Marques Concept is a unique, beautiful, and a powerful machine that showcases the importance of design and individuality. If you’re a fan of breathtaking motorcycles that can make heads turn, then this bike is definitely for you.

There are motorcycles that follow rules, and then there are machines built to break them completely.

The TB Frames Racing Series “Grand Prix 2” by Thunderbike belongs firmly in the second category. Built in 2017 as part of Thunderbike’s exclusive Racing Series, this motorcycle is a bold fusion of drag racing engineering and custom craftsmanship, designed to deliver both extreme performance and undeniable visual impact.

From the first glance, the silhouette tells the entire story. The bike sits long, low, and aggressively stretched, built around a Thunderbike dragster frame with a dramatic 36° steering head tilt. This extreme geometry defines its identity, giving it a presence that feels fast even at a standstill. The extended front end, enhanced by a Thunderbike GP setup with an additional 1.5° rake, pushes the proportions even further, creating a machine that looks like it belongs on a drag strip rather than a public road.

At the heart of the build lies the powerful Harley-Davidson Screamin’ Eagle 110ci engine, a Twin Cam EFI unit known for its torque and raw character. This engine provides the perfect foundation for a bike of this caliber, delivering strong, immediate power that matches the aggressive design. Paired with an NH Power primary and a full Thunderbike Grand Prix exhaust system, the sound and performance combine to create a truly visceral riding experience.

The engineering behind the Grand Prix 2 goes far beyond the engine. Every structural and mechanical component has been carefully designed to support both performance and aesthetics. The Thunderbike RS singleside swingarm adds a clean and technical look to the rear while maintaining strength and stability. The Air Ride suspension system allows the bike to shift between a low, show-ready stance and a more practical riding position, offering versatility without compromising its radical design.

The wheel setup is one of the most defining features of this build. At the front, a massive Thunderbike Grand Prix 4×23 wheel is fitted with an Avon 130/60-23 tire, creating a tall and dominant front profile. At the rear, a 9×21 wheel wrapped in a Metzeler 260/35-21 tire provides a wide, muscular foundation. This combination reinforces the drag-inspired stance and ensures that the bike maintains a strong and stable presence on the road.

Braking performance is equally impressive, featuring a **Brembo radial front caliper paired with a 340mm Thunderbike brake disc. At the rear, a Nissin 6-piston perimeter brake system combined with a 21-inch Thunderbike disc delivers both stopping power and visual impact. These high-performance components ensure that the bike’s power is matched by precise control.

What truly elevates the Grand Prix 2 is the level of integration across every detail. Thunderbike has developed nearly all components in-house, including the fuel tank, fenders, handlebars, grips, forward controls, air cleaner, and headlamp. This results in a motorcycle that feels cohesive and purpose-built, where every element contributes to the overall design and function.

The final layer of this build comes from the paintwork, executed by Ingo Kruse of Kruse Design. The finish enhances the bike’s sharp lines and aggressive proportions, turning it into a true piece of rolling art. It’s a visual identity that perfectly complements the engineering beneath.

The Grand Prix 2.0 is more than just a custom motorcycle—it’s a statement of what happens when racing inspiration meets uncompromising design. It captures the essence of speed, power, and innovation, blending dragster aesthetics with street presence in a way that very few bikes can achieve.

For those who appreciate extreme custom builds and high-end craftsmanship, the TB Frames Racing Series “Grand Prix 2” stands as a true icon—an unapologetic machine built to push boundaries and redefine expectations.

As Thunderbike evolved from a motorcycle shed, Frank has also grown over the past 35 years. From mopeds to Suzuki, and eventually to his second custom bike, he has been on this journey with us. Now, a new project is on the horizon: a Radical Over frame powered by a 110 Harley engine will serve as the foundation for his latest bike.

The biker from Neuss is fully committed to this project and willingly makes the 100-kilometer journey to Thunderbike to check out the latest progress on his bike. Back in 2004, our custom mechanic Rainer built Frank’s first Harley, a freestyle-based custom bike.
