Slip-On System:

Scorpion’s expert technicians have developed a ready-to-install performance slip-on system specifically for the Honda CB125R Euro 5+ model. Explore the specifications and available options below!

What are the benefits of a slip-on system? Their easy installation makes them a popular choice among riders seeking a quick and effective upgrade. Slip-on systems do not interfere with factory emission devices and include either an integrated link pipe or a small link pipe with a slip joint for a secure fit.

Despite their seemingly simple design, Scorpion’s precisely engineered and acoustically tuned silencers — featuring specialized, unique internals and fillings — deliver exceptional performance gains by reducing restriction and optimizing exhaust gas flow. The result? Sharper throttle response, increased power, reduced weight, and a signature sound enhancement — all while remaining the top choice for enthusiasts and riders looking to unlock their bike’s full potential.

Red Power: Designed with a shorter, retro-inspired compact appearance, it delivers a bold, guttural soundtrack that amplifies your bike’s personality.

Brushed Stainless: Crafted from premium T304 stainless steel and meticulously hand-finished, this piece boasts a modern, textured appearance that exudes quality and durability. (Available for Serket Parallel / Red Power silencer only.)

Black Ceramic: The matte black finish provides a stealthy, modern look. The silencers undergo a specialised coating process, ensuring a durable and flawless finish. (Available for Red Power silencer only.)
