ELECTRIC CUSTOM
Silent Predator: The Ultimate Shark
Taiwan's HERZ-FORM transforms the Yamaha EC-05 electric scooter into a silent, street-hunting predator with a world-class parts list.
In the world of vehicle customization, a roar is the classic signal of intent. But what if the most aggressive presence on the street is the one you can't hear coming? From Taiwan, HERZ-FORM answers that question with their "Ultimate Shark," a Yamaha EC-05 build that channels predatory instinct without the noise. The shop’s philosophy puts it simply: "a frequency felt by the heart, without the roar of an engine." This project isn't just a graphics package on a stock scooter; it's a top-to-bottom re-engineering of what an electric custom can be, blending a fierce visual identity with a roster of top-tier performance parts.
Chapter 01
The Silent Heart
At the core of this predator is a powertrain built for instant, silent torque. The stock motor was swapped for a custom unit from JZ BIKES, paired with a complete LMG belt drive system that utilizes a lightweight carbon fiber belt. Power delivery is further refined with a custom LMG rear pulley and a distinctive yellow LMG motor cover. This combination focuses on efficient, quiet performance, proving that thrilling acceleration doesn't need to be announced by an exhaust. Every component, from the motor mount to the belt itself, is a deliberate choice to create a responsive and unique electric driving experience, fully embracing the nature of the EV platform.

An Apex Predator's Stance
To handle the city streets, the EC-05's chassis has been thoroughly fortified. The front end is now managed by a set of high-performance GJMS FS-X inverted forks, a significant upgrade providing superior damping and rigidity. These are paired with a Brembo 1098 monobloc radial caliper—a component usually found on superbikes—gripping a BPF floating disc. The rear features a D2 DDXPRO shock system and a Brembo CNC 'crab' caliper. The entire package rolls on staggered FASS-MAXI forged wheels, 14-inch in the front and 13-inch in the rear, giving the scooter an aggressive, forward-leaning stance that looks ready to pounce.

Chapter 05
Shark Skin and Blood-Red Eyes
The build's visual identity is its most striking feature. A full-body vinyl wrap by Who's Rock, inspired by the powerful form of a shark, creates a sense of motion and aggression. Jagged black-and-white patterns are punctuated by a 'face' on the front fairing, complete with bared teeth and blood-red 'eyes' courtesy of a 75w Devil's Eye headlight. The theme is reinforced by functional aero, including custom winglets from HERZ-FORM and a host of carbon fiber parts. From the front fender to the windscreen and rear hugger, the lightweight carbon adds a touch of racing technology while completing the menacing aesthetic.
