British scooter style meets uncompromising racing DNA: the SCORPION Serket Parallel exhaust system gives the Royal Alloy the sporting presence its classic lines deserve. The compact brushed stainless steel silencer sits dynamically beneath the side panel, creating a powerful technical contrast to the elegant retro styling of the GP, TG and JPS.
But this system is about much more than looks. Scorpion develops performance exhaust systems backed by decades of motorsport experience and manufactures the Serket Parallel from high-quality motorsport-grade T304 stainless steel. The result is a lightweight, precisely engineered system with a distinctive sound and a significantly sportier character.
The Serket Parallel silencer combines clean, modern lines with a design that immediately communicates performance. The brushed stainless steel sleeve has a sophisticated technical appearance, while the dark end cap creates a striking contrast. The distinctive red ring around the outlet provides the finishing touch – a small but unmistakable detail that highlights Scorpion's racing heritage.
The system also makes a strong impression when fitted to the scooter. Its compact silencer follows the lines of the Royal Alloy closely and visually exposes more of the rear wheel. Combined with the classic Royal Alloy bodywork, it creates an exciting blend of British scooter heritage and modern motorsport engineering.
Scorpion uses high-quality T304 stainless steel, a material valued for its strength, corrosion resistance and durability. The brushed finish deliberately emphasises the technical character of the exhaust. Exposed metal surfaces, precise joints and carefully executed construction make it immediately clear that this is no ordinary standard exhaust system.
Scorpion's published figures demonstrate that the Serket Parallel has been developed for more than just appearance. The Scorpion system weighs only 2.56 kg, compared with 4.42 kg for the standard exhaust. This represents a weight saving of approximately 1.86 kg.
The exhaust also demonstrates its sporting credentials on the dyno. Scorpion specifies a measured output of 8.26 BHP, compared with 6.92 BHP using the standard exhaust system. This represents a measured increase of approximately 1.4 BHP – a remarkable difference for a 125cc engine and exactly the kind of performance upgrade that suits the uncompromising character of this system.
A Scorpion exhaust is not designed to whisper like a standard system. The high-flow Serket Parallel silencer gives the Royal Alloy a noticeably more emotional and performance-focused exhaust note. The result is a deeper, sportier presence that gives the 125 engine more acoustic character and makes every acceleration feel that little bit more intense.
The exhaust system has been developed specifically for the vehicle. According to Scorpion, installation requires neither cutting nor ECU remapping. The system includes the Serket Parallel silencer, connecting pipe, model-specific mounting bracket and the required mounting hardware.
Important: This exhaust system has no E-mark approval and is intended exclusively for racing purposes. It is not approved for use on public roads.
A Royal Alloy embodies classic British scooter styling – the SCORPION Serket Parallel introduces another side of British two-wheel culture: motorsport, performance and uncompromising sound. Brushed stainless steel, dark racing details and the unmistakable red ring around the outlet transform the restrained standard exhaust into a genuine statement.
For riders who want more than standard styling and a standard exhaust note, the Serket Parallel is much more than just a replacement silencer. It gives the Royal Alloy a character that is not only seen, but heard and experienced.
